Detailed explanation-1: -Troposphere. The troposphere is the lowest and densest layer of the atmosphere and according to NIWA, approximately 75% of all the air in the atmosphere is found in this layer. The troposphere extends from Earth’s surface to approximately 5 to 9 miles (8 to 14.5 km) high.

Detailed explanation-2: -The Troposphere This is the layer we live in and contains most of what we consider to be “the atmosphere, ” including the air we breathe and nearly all of the weather and clouds we see. In the troposphere, the temperature of the air decreases the higher you go.

Detailed explanation-3: -The atmosphere surrounds the Earth and holds the air we breathe; it protects us from outer space; and holds moisture (clouds), gases, and tiny particles.

Detailed explanation-4: -Earth’s atmosphere is composed of about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.1 percent other gases. Trace amounts of carbon dioxide, methane, water vapor, and neon are some of the other gases that make up the remaining 0.1 percent.

Detailed explanation-5: -Earth’s atmosphere has five major and several secondary layers. From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere.
