List two of the thermosphere and describe word each begins above Earth's surface?
The two layers that make up the thermosphere are the thermopause, which starts at around 500 km above the Earth's surface, and the exosphere, which begins around 700 km above. The thermopause is the boundary that marks the transition from the thermosphere to the exosphere, where the density of molecules is extremely low.
Is the earth atmosphere made up of 4 layers?
There are five major layers of the Earth's atmosphere (the others are parts of the layer). From lowest to highest: 1.Troposphere [Tropopause] 2. Startosphere [ Ozone Layer, Stratopause] 3. Mesosphere [Mesopause] 4. Thermosphere [ Thermopause, Ionosphere] 5. Exosphere [Exobase]
Which layer of the Earth is 2000 degrees?
ThermosphereTemperature increases with height in the thermosphere from the mesopause up to the thermopause, then is constant with height. The temperature of this layer can rise to 1,500 °C (2,730 °F), though the gas molecules are so far apart that temperature in the usual sense is not well defined. The International Space Station orbits in this layer, between 320 and 380 km (200 and 240 mi). The top of the thermosphere is the bottom of the exosphere, called the exobase. Its height varies with solar activity and ranges from about 350-800 km (220-500 mi; 1,100,000-2,600,000 ft).
What are the major characteristics of the layers of the atmosphere?
there are 5 layers of the atmosphere :-troposphere ( our layer)-stratosphere ( the layer which contains the ozone layer)-mesosphere (the coldest layer)-thermosphere (the hottest layer)-exosphere ( the layer that leaves into space)
Where is The thermopause located?
The thermopause is located at the top of the thermosphere, but still below the exosphere.
Is there a well defined thermopause?
Yes, the thermopause is a well-defined boundary in the Earth's atmosphere, located at an altitude of about 500 to 1,000 kilometers (310 to 620 miles) above the Earth's surface. It marks the transition between the thermosphere, where temperatures can reach up to 2,500°C (4,500°F) or higher, and the exosphere, where atmospheric particles are sparse and can escape into space. The thermopause is not a rigid boundary but rather a gradual transition zone influenced by solar activity and atmospheric conditions.

Does the thermosphere have a definite outer limit?
No it does not.The altitude of its higher boundary, known as the thermopause and exobase, ranges from about 250 to 500 kilometres (160 to 310 mi) depending on solar activity.
Which atmospheric level is farthest from the litosphere?
This idea is still be debated, it is either the thermosphere or the exosphere. The exosphere has such a low level of air that some scientists question whether it is just an extension of the vacuum of space. The two layers are separated by the thermopause, an imaginary boundary. The thermosphere varies in height between 500km to 1000km due to radiation differences whereas the exosphere has no upper limit but generally considered to be 100000km. The ISS (International space station) operates within the thermosphere at 330km.
How far above the earth is the zone were the space ship heats up coming back to earth?
The zone where a spacecraft begins to heat up during re-entry into Earth's atmosphere is typically around 70 miles (about 113 kilometers) above the surface. This region, known as the "thermopause," marks the transition from space to the atmosphere, where friction with air molecules generates intense heat. As the spacecraft descends, it experiences increasing atmospheric density, leading to significant heating due to aerodynamic drag.

What are the cloud layers in order?
Clouds are classified into 4 main layers, with one layer which occurs extremely high up. They can be divided into the four 'families'. High clouds, which are Family A Middle clouds, which are Family B Low clouds, which are Family C Vertical clouds, which are Family D High clouds, which include ones such as Cirrocumulus and Cirrus clouds, occur at heights of around 30,000 feet. They generally have a very wispy appearance, generally due to the fact that a large portion of them are ice crystals. This is because the temperature at these altitudes can be well below freezing point. Middle clouds, such as the Altostratus cloud, are found at about 15,000 feet. The Altostratus cloud is generally grey or dark, like a rain cloud. However they are not so dark that you cannot see the sun through them! Low clouds include Cumulus, Stratocumulus and Cumulonimbus clouds. They are found around 6,500 feet, and are characterised by their much more defined 'cloud like' features. Cumulus clouds are the stereotypical cloud, quite heavy with a whispy edges. Cumulonimbus clouds however are storm clouds, and are very tall and dense. The heigh can reach well over 50,000 feet! The other cloud group appears in the mesosphere and the stratosphere, which is just below the mesosphere. They are typically made completely from ice due to the high altitudes.

Name the five layers of earth's atmosphere and conditions?
Earth's atmosphere can be divided into five main layers. These layers are mainly determined by whether temperature increases or decreases with altitude. From highest to lowest, these layers are:ExosphereThe outermost layer of Earth's atmosphere extends from the exobase upward. Here the particles are so far apart that they can travel hundreds of km without colliding with one another. Since the particles rarely collide, the atmosphere no longer behaves like a fluid. These free-moving particles follow ballistic trajectories and may migrate into and out of the magnetosphere or the solar wind. The exosphere is mainly composed of hydrogen and helium.ThermosphereTemperature increases with height in the thermosphere from the mesopause up to the Thermopause then is constant with height. The temperature of this layer can rise to 1,500 °C (2,730 °F), though the gas molecules are so far apart that temperature in the usual sense is not well defined. The ISS orbits in this layer, between 320 and 380 km (200 and 240 mi). The top of the thermosphere is the bottom of the exosphere, called the exobase. Its height varies with solar activity and ranges from about 350-800 km (220-500 mi; 1,100,000-2,600,000 ft).MesophereThe mesosphere extends from the stratopause to 80-85 km (50-53 mi; 260,000-280,000 ft). It is the layer where most meteors burn up upon entering the atmosphere. 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 −100 C(−148.0 F; 173.1 K).StratrosphereThe stratosphere extends from the tropopause to about 51 km (32 mi; 170,000 ft). Temperature increases with height, which restricts turbulence and mixing. The statrosphere, which is the boundary between the stratosphere and mesosphere, typically is at 50 to 55 km (31 to 34 mi; 160,000 to 180,000 ft). The pressure here is 1/1000th sea levelTroposphereThe troposphere begins at the surface and extends to between 7 km (23,000 ft) at the poles and 17 km (56,000 ft) at the equator, with some variation due to weather. The troposphere is mostly heated by transfer of energy from the surface, so on average the lowest part of the troposphere is warmest and temperature decreases with altitude. This promotes vertical mixing (hence the origin of its name in the Greek word trope, meaning turn or overturn). The troposphere contains roughly 80%of the mass of the atmosphere. The tropopause is the boundary between the troposphere and stratosphere.
