What does ATM mean in ACADEMIC & SCIENCE

An atmosphere is a layer of gases that surround a planet or moon. It serves to protect the planet from radiation, by providing thermal insulation and preventing solar wind from stripping away the surface material.

The layers of an atmosphere include the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. These different layers are each characterized by distinct temperatures and chemical compositions which serve as barriers against certain threats.

Atmospheric composition and temperature can strongly influence local weather patterns. Wind circulation patters created by air pressure differences drive storms, while atmospheric moisture helps determine precipitation levels.

Yes, Earth's atmosphere is constantly changing due to both natural processes like seasonal changes as well as human activities such as burning fossil fuels which release carbon dioxide into the air.

Nitrogen makes up about 78% of the Earth's atmosphere, followed by oxygen at 21%, argon at 0.9%, and carbon dioxide at 0.04%. There are also trace amounts of other gases like water vapor and methane in our air.

Atmospheric pressure decreases quickly with increasing altitude, since there are fewer molecules per unit area at greater heights above sea level. At about 18 km above sea level, around half of air pressure is lost compared to sea level conditions.

Yes, temperature varies quite drastically throughout different layers in an atmosphere – for example in Earth’s lower troposphere temperatures decrease steadily with increasing altitude, whereas in Earth’s stratosphere they actually increase with height instead!

In order for clouds to form in an atmosphere there needs to be condensation nuclei (e.g., dust or smoke particles) which act as surfaces for water vapor molecules to condense on in order to become liquid droplets or ice crystals - this usually happens when warm moist air rises up and cools down quickly enough!

Yes – human activity such as burning fossil fuels has already led to major increases in carbon dioxide content within the Earth’s lower troposphere which has had significant effects on global climate patterns due to enhanced greenhouse warming effects amongst other factors.
