Detailed explanation-1: -The troposphere is the lowest layer of Earth’s atmosphere. Most of the mass (about 75-80%) of the atmosphere is in the troposphere. Most types of clouds are found in the troposphere, and almost all weather occurs within this layer.

Detailed explanation-2: -The troposphere contains approximately 80% of the mass of the atmosphere of the Earth. The troposphere is denser than all its overlying atmospheric layers because a larger atmospheric weight sits on top of the troposphere and causes it to be most severely compressed.

Detailed explanation-3: -The troposphere is thickest at the equator, and much thinner at the North and South Poles. The majority of the mass of the entire atmosphere is contained in the troposphere-between approximately 75 and 80 percent.

Detailed explanation-4: -The troposphere is the shortest layer of the atmosphere. It rises to only about 12 kilometers (7 miles) above the surface. Even so, this layer holds 75% of all the gas molecules in the atmosphere. That’s because the air is densest in this layer.

Detailed explanation-5: -The troposphere is the densest layer of the atmosphere containing 80% of its mass. This is because all the other layers of the atmosphere sits on top of the troposphere compressing it. The troposphere is mostly a mixture of just 2 gases.
