Atmosphere

• Troposphere - In this layer, air is denser as the weight of the air above it pushes the air molecules close together.
• Troposphere -  Most of the water vapor in the atmosphere is found in this layer
• Troposphere - Clouds and storms occur in this layer.
• Tropopause - boundary between the troposphere and the startosphere.
• Troposphere - Very little water vapor is present in this layer.
• Stratosphere - There are no clouds int he stratosphere.
• Stratosphere - The ozone layer which shields Earth from harmful UV radiation, is found at the topmost part of the startosphere, which is warm.
• Stratosphere - In this layer, temperature increases with height because one comes closer to the ozone layer.
• Mesosphere - In this layer, temperature decreases with height
• Mesosphere - This is the coldest ergion of the atmosphere.
• Thermosphere - This process, in turn, raises the temperature of the air in the ionosphere.
