Detailed explanation-1: -Earth’s atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. These gases are found in atmospheric layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure.

Detailed explanation-2: -An atmosphere contains the air that we breathe and is a blanket of gases that surrounds Earth. It is held near the surface of the planet by Earth’s gravitational attraction. A barometer is used to measure air pressure. Argon, oxygen and nitrogen from the three main constitutions of the atmosphere.

Detailed explanation-3: -ATMOSPHERE :-It means mixture of gases surrounding the Earth. It contains the mixture of several gases such as oxygen ( roughly 21% ), nitrogen (78%), carbon dioxide (0. 04%) and other gases in a small amount.

Detailed explanation-4: -Expert-Verified Answer The mixture of gases that surrounds the earth is called the Air. Explanation: Air is a combination of gases that make up the Earth’s atmosphere, which remains in orbit around our planet owing to gravity’s attraction.

Detailed explanation-5: -The space around us is filled with air and dust particles. This layer of air surrounding the earth’s unit surface area is called the atmosphere. Atmospheric air extends many kilometres above the earth surface.
