The layer of the atmosphere closest to Earth is the troposphere. Itextends up to about 30,000 feet above the Earth's surface.
The coldest layer of the atmosphere is the exosphere (space). If you were to not count the exosphere, the coldest layer would be the mesosphere.
this is because of temperature inversions as the altitudegoes up the temperature goes down. so the coldest part really isthe top of the mesosphere.
The coldest layer is actually around the Mesopause -- where the Mesosphere and thermosphere meet. (\ /) (^-^) (U U) u u
From Wikipedia: Temperature decreases with height in the mesosphere. The mesopause, the temperature minimum that marks the top of the mesosphere, is the coldest place on Earth and has an average temperature around â100 Â°C (â148.0 Â°F; 173.1 K) the mesosphere is the coldest layer in …the atmosphere. It contains the ozone.. OK!! the answer above is incorrect the coldest layer in the atmosphere is the Mesopause its the thin layer between the Mesosphere and Thermosphere. Also the Ozone is in the Stratosphere. . Actually its correct because the mesopause is a part of the mesosphere.... . ok the 1st and 3rd answers are wrong! i should know im learning this in my 7TH GRADE SCIENCE CLASS! the ozone is in the stratosphere, the second closest layer to the earth. STUPIDS! (MORE)
The coldest layer of the atmosphere is the mesosphere. It is around -80 degrees C
1. Troposphere (8-18km above Earth's surface). 2.Stratosphere (50km above Earth's Surface). 3. Mesosphere (50-85km). 4.Thermosphere (85-450km). 5.Exosphere (450-10,000km)
The Troposphere is nearest and extends from the surface of the earth to approximately 10 thousand metres above the surface. This explains why the air is described as being 'thin' when at the top of some of the highest mountains of the World. Hope this helps.
The coldest layer of the earth's atmosphere is the mesosphere. Theair is very thin in this layer of the atmosphere.
The thermosphere is the highest layer that contains enough molecules (notably oxygen) to absorb thermal energy from sunlight. Although it is technically very hot, it is also nearly a vacuum by atmospheric standards, which means very little energy can actually be transferred. Most orbital space fli…ghts, and the International Space Station, are within the thermosphere. The tiny amount of atmospheric friction there is still enough to slow a satellite over a long period of time, causing many (such as Skylab) to fall from orbit. (MORE)
The Exosphere is the farthest atmospheric layer. . Here is a link to suppor thishttp:/en.wikipedia.orgwiki/Exosphere
the layers of the atmosphere are the troposphere, the stratosphere, the mesosphere, then the thermosphere. they are in order.
The layers of the atmosphere are thetroposhphere where most of the weather occurs and this is the layer we live on. The stratospher is the layer that contains thes ozone and 19% of the gasses. The moseospher is the thirs layer and is the coldest plus meteors burn up in this layer. The thermospher is… the 4th layer and the warmest. The exosphere is the outer most layer and is often called outerspace. (MORE)
The atmosphere layer that is thinnest in size is the upper layer, the exosphere. 1. The troposphere is the first layer above the surface and contains half of the Earth's atmosphere. Weather occurs in this layer. 2. Many jet aircrafts fly in the stratosphere because it is very stable. Also, the… ozone layer absorbs harmful rays from the Sun. 3. Meteors or rock fragments burn up in the mesosphere. 4. The thermosphere is a layer with auroras. It is also where the space shuttle orbits. 5. The atmosphere merges into space in the extremely thin exosphere. This is the upper limit of our atmosphere. (MORE)
The mesohere,the boundary between the Thermosphere and Mesosphere, is technically the coldest place on Earth, with a temperature of â100 degrees Celsius (â148.0 degrees fahrenheit; 173.1 K).
The Troposhere is the closest layer. It contains approximately 75% of the atmosphere's mass and (99%) almost all of its Water Vapor And Areosols
i think or should i say i know that the inner core is the hottest layer of the earth it is because it is closer to the sun
Its a layer in the mesosphere, called the mesopause .This is just before the thermosphere. The mesopause can be around-100Â°C (-146Â°F) in temperature and is located at altitudes between85 and 100 km. The top of the Mesosphere is the coldest area, just before we gointo the next layer called …the Thermosphere. At the top of theMesosphere, at 50 miles (260,000 feet) up, the temperature isaround -85'C (-120'F). This area is known as the mesopause. (MORE)
The mesosphere is the layer of the atmosphere that exists betweenthe stratosphere and the thermosphere. It contains the coldestparts of the Earth's atmosphere, reaching temperature depths of-90ÃÂ°C.
I think there are 5 layers in our atmosphere; It is thickest near the surface and thins out with height until it eventually merges with space. .

the whole list of Earths atmosphere is the Troposphere, Stratosphere, Mesosphere, Thermosphere, Ionosphere, and the exosphere
That depends on what you mean by the "first" layer.\n. \nThe lowest layer (the first off the ground) is the Troposphere.\n. \nThe highest layer (the first coming in from space) is the Exosphere.
The ozone layer (molecular formula O3) filters out most of the UV-A and UV-B rays which can harm organisms by damaging DNA within their cells. This layer is mainly in the stratosphere which is 10-50km above the earth's surface where the conditions persist which allow ozone to be formed. If you broug…ht all of the ozone in the atmosphere down to sea level it would make a layer less then 1mm thick!! Hense protecting it by reducing production of CFCs (1 molecule of CFCs destroys around 1000 molecules of ozone) is so important (MORE)
The five layers of Earth's atmosphere are: 1. Troposphere 2. Stratosphere 3. Mesosphere 4. Thermosphere 5. Exosphere
The Layer of the Atmosphere which is closest to the earth's surface is the Troposphere
They are best known as; Troposphere, Stratosphere, (normally considered as under the ozone layer), Mesosphere, and, normally 'Thermosphere'. That is however rather old 'science', as the definable layers continue to the 'Exosphere' layers, or Ionosphere and Plasmasphere, which are part of the Magnet…osphere, which is not spherical but toroidal (donut shaped). Strictly the 'atmosphere' itself is the lower oxygen rich layer below the Mesosphere, but the word is also 'stretched,' due to want of another, to describe the (ever 'extending') whole structure inside the Earth Centred Inertial (ECI) Frame inside the ionized layer of the bow shock, which all orbits the sun.

The third layer of the earth's atmosphere is the Mesosphere, where meteors can be found.
The most widely used analysis of Earth's atmosphere is into five layers. From the surface of the planet out into space, they are: Troposphere - from the surface to between 7 and 17 km (depending on latitude) Stratosphere - Tropospheric boundary to about 50 km Mesosphere - ~50 km to ~85 km Ther…mosphere - ~85 km to between 350-800km (depending on solar activity) Exosphere - Thermospheric boundary to ~10,000 km (MORE)
The atmosphere is defined as the mixture of air above the earth's surface, all the way to space. There are different layers of the atmosphere, defined in different ways (for example, composition, temperature characteristics, etc.). The troposphere is the layer closest to the earth.
The outermost layer of earth's atmosphere is Thermosphere. It is the one in which satellite's fly.
This is the troposphere. This is the layer where weather occurs. The stratosphere is just above it, housing the ozone layer.
The lowest is the troposphere, which is the layer that provides most of our weather. It contains about 80% of the Earth's air, but extends only to a height of about 11 miles (17 kilometers) at the Equator and less at the Poles.
here they are in order: electrosphere, troposphere, ozonosphere, stratosphere, mesosphere, thermosphere, ionosphere, magnetosphere, plasmasphere, exosphere, and gravisphere
the density and temperature of the layers. The farther you go up, the less dense each layer is.
The earth's atmosphere is separated into 4 main layers: . The troposphere, . The statosphere, . The mesosphere and . The thermosphere The Troposphere: The layer of the atmosphere closest to the Earth's surface, extending up to about 10-15 km above the Earth's surface. It contains 75% of the… atmosphere's mass. The troposphere is wider at the equator than at the poles. Temperature and pressure drops as you go higher up the troposphere. The Tropopause: At the very top of the troposphere is the tropopause where the temperature reaches a (stable) minimum. Some scientists call the tropopause a "cold trap" because this is a point where rising water vapour cannot go higher because it changes into ice and is trapped. If there is no cold trap, Earth would loose all its water! The uneven heating of the regions of the troposphere by the Sun causes convection currents and winds. Warm air from Earth's surface rises and cold air above it rushes in to replace it. When warm air reaches the tropopause, it cannot go higher as the air above it (in the stratosphere) is warmer and lighter ... preventing much air convection beyond the tropopause. The tropopause acts like an invisible barrier and is the reason why most clouds form and weather phenomena occur within the troposphere. The Greenhouse Effect: Heat from the Sun warms the Earth's surface but most of it is radiated and sent back into space. Water vapour and carbon dioxide in the troposphere trap some of this heat, preventing it from escaping thus keep the Earth warm. This trapping of heat is called the "greenhouse effect". However, if there is too much carbon dioxide in the troposphere then it will trap too much heat. Scientists are afraid that the increasing amounts of carbon dioxide would raise the Earth's surface temperature, bringing significant changes to worldwide weather patterns ... shifting in climatic zones and the melting of the polar ice caps, which could raise the level of the world's oceans. STRATOSPHERE This layer lies directly above the troposphere and is about 35 km deep. It extends from about 15 to 50 km above the Earth's surface. The lower portion of the stratosphere has a nearly constant temperature with height but in the upper portion the temperature increases with altitude because of absorption of sunlight by ozone. This temperature increase with altitude is the opposite of the situation in the troposphere. The Ozone Layer: The stratosphere contains a thin layer of ozone which absorbs most of the harmful ultraviolet radiation from the Sun. The ozone layer is being depleted, and is getting thinner over Europe, Asia, North American and Antarctica --- "holes" are appearing in the ozone layer. MESOSPHERE Directly above the stratosphere, extending from 50 to 80 km above the Earth's surface, the mesosphere is a cold layer where the temperature generally decreases with increasing altitude. Here in the mesosphere, the atmosphere is very rarefied nevertheless thick enough to slow down meteors hurtling into the atmosphere, where they burn up, leaving fiery trails in the night sky. THERMOSPHERE The thermosphere extends from 80 km above the Earth's surface to outer space. The temperature is hot and may be as high as thousands of degrees as the few molecules that are present in the thermosphere receive extraordinary large amounts of energy from the Sun. However, the thermosphere would actually feel very cold to us because of the probability that these few molecules will hit our skin and transfer enough energy to cause appreciable heat is extremely low.

Well, the Ozone layer is part of Earth's atmosphere, so it is both. The atmosphere is what makes the sky blue.
Any satellite would have to orbit Earth outside the atmosphere. If it orbits a an altitude at which there is still a significant amount of atmosphere, it would quickly lose energy and crash towards Earth.
the third layer of the atmosphere would be the mesosphere . this is the layer that burns up the meteorites before they reach earth.
The coldest layer of the atmosphere is in the Mesosphere. This is because temperatures are decreasing as the Mesosphere extends upward above the Stratosphere. The air is thinner because the air particles are further apart. The next layer, known as the Thermosphere is the hottest layer. The reason wh…y this layer is so hot, is because it contains fewer air molecules then the other layers, making the air very thin and easy to warm. The Thermosphere is closest to the sun and most sensitive to solar energy which is why it gets hot very quickly. (MORE)
There are four spheres of Earth. Hydrosphere (water), atmosphere (air), geosphere (land), and biosphere (life).
The function of ozone layer is to protect us from sun's harmful UVrays. It is present in the stratospheric region.
The main function of ozone layer is to stop the harmful UV radiations coming from the sun. These are high energy waves that can cause serious damage to living organisms.
The four layers that constitute the earths atmosphere in order from space to the earths surface are as follows: Inosphere (aka. Aurora) @ 350km, Mesosphere @ 90-350km, Stratosphere @ 50-90km, and Troposhere @18-50km. It's composition is 79% Nitrogen, 20% Oxygen, and 1% other gases.
Yes, the ozone layer is a part of the earth's atmosphere. It ispresent in the startospheric region of the atmosphere.
No. The atmosphere is the least dense layer. The densest layer is the inner core.
The atmosphere protects the earth, it abosrbs the gamma rays and other harmful light rays
Friction. Let's talk about "coldest layer" for a minute. The temperature profile of the atmosphere drops pretty sharply fromthe surface up to about 10km, stays more or less constant up to20km, then starts gradually increasing again to a peak (still lowerthan surface temperature) around 50km, drops …gradually to a minimumaround 90km, then increases very sharply again above that, reachingsurface temperatures again around 110km and continuing to increasebeyond that. So the coldest layer is that from around 80-100 km. To meteors, the actual temperature of the atmosphere doesn't matterall that much. Even at the surface (which is considerably warmerthan the region they mostly burn up in), the temperature is nothigh enough to burn up a meteor. Melt, maybe, if it were made ofice, but not much more than that. What happens instead is that the fast-moving meteor compresses (andtherefore heats ... Ideal Gas Law) the air in front of it by a lot.Also, the friction of the air rushing past the meteor heats boththe air itself and the meteor. That's what makes them "burn up",not the temperature of the atmosphere itself. (This does lead to the question of why they don't burn up evenhigher where the temperature is higher, and the reason for that isthat temperature is a measure of the average kinetic energy ofmolecules. Molecules above 110 km have a lot of kinetic energy per molecule , but there aren't that many of them, so the overall energy is still low, and the meteor has littleproblem radiating away the small amount of energy it picks up fromthem.)

The coldest layer of earth's atmosphere is the Mesosphere. This isthe top layer of the Mesosphere.
Why do meteors burn in the mesosphere before entering the earth even if it is the coldest layer of the atmosphere?
The incandescence of a meteor is caused by friction between thesurface of the meteoritic body and Earth's atmospheric gas. The gasdoes not have to be hot to cause the "burning" the energy for thiscomes from the speed of the meteor as friction with the gas slowsit down. Rather like car/bicycle brakes… heating up when they areapplied. (MORE)
