Atmospheric Sciences

The atmospheric layer containing pollution is troposphere. It the nearest to earth.

Carbon Dioxide: CO2 is a Single Carbon, Double Oxygen molecule. Carbon Dioxide is a partial product of respiration and is a component of the atmosphere. It is also necessary in the photosynthesis reaction that turns sunlight into sugars within plant cells.

An atmosphere containing a flammable gas is ignitable when it falls within a specific concentration range known as the flammable or explosive limits. This range is defined by the lower explosive limit (LEL), below which the concentration is too low to ignite, and the upper explosive limit (UEL), above which there is insufficient oxygen for combustion. Additionally, an ignition source, such as a spark or open flame, must be present for ignition to occur. Proper safety measures are crucial to prevent ignition in environments with flammable gases.

The flamelike columns of gas that continually erupt from the lowest layer of the Sun's atmosphere are known as solar prominences. These large, bright features extend outward from the Sun's surface and are composed of plasma, which is a hot, ionized gas. Solar prominences are often associated with solar activity, such as sunspots and solar flares, and can last for days to weeks before dissipating or collapsing back into the Sun's atmosphere.

Astronauts travel in space and escape earth's atmosphere by wearing gravity resistant suits and traveling to outer space in a space shuttle that is insulated against the elements.

Nothing - the length of 'day' on any planet - is the time it takes to revolve once on its axis. Relating to the Earth - that's approximately 23 hours 56 minutes.

The thermosphere and exosphere are the warmest layers of the Earth's atmosphere because they receive intense solar radiation. In the thermosphere, solar energy is absorbed by a small number of gas molecules, raising their temperatures significantly, sometimes exceeding 1,500 degrees Celsius (2,732 degrees Fahrenheit). The exosphere, which is the outermost layer, contains very sparse particles that can also absorb solar radiation, leading to high temperatures despite the low density of matter. However, this heat isn't felt in the same way as at lower altitudes due to the lack of air pressure and density.

The troposphere. Pressure decreases as elevation increases.

This gas is argon.

The upper layers of the atmosphere are heated from above, while the lower layers are heated from below, because infrared radiation is given off by the Earth's surface in response to solar heating. The lower troposphere (with its denser molecules and water vapor) receives heat from both re-radiation and convection.

The result is that while the atmosphere always gets thinner with altitude, the temperature decreases with altitude in the troposphere, then increases with altitude in the stratosphere. The very high temperatures in the thermosphere are moot because of the low specific heat (energy capacity) of the tenuous gases there.

Meteor is the term used to describe the streak of light (also called a shooting star) that passes through the atmosphere. The light is caused when a meteroid hits the atmosphere and burns up.

Oxygen is the gas that makes up the second most volume in the atmosphere, after nitrogen.

A breathable atmosphere primarily contains oxygen (around 21%) and nitrogen (about 78%), along with trace amounts of other gases such as carbon dioxide, argon, and water vapor. The presence of oxygen is essential for human and animal life, while nitrogen helps to dilute oxygen and prevent rapid combustion. Additionally, the atmosphere must have a suitable pressure and temperature to support life. Contaminants or pollutants can significantly affect the quality and safety of a breathable atmosphere.

oxygen . hey people googling there science hw. join the club :)

The stratopause is not a region of the atmopshere. it is the border between the stratosphere below anjd the mesosphere above. It is located 31 to 34 miles above the surface.

Carbon dioxide (CO2) and methane (CH4) are two forms of carbon found in the atmosphere.
