Describe the 4 characteristics of the Stratosphere ?

The temperature increases with height where the stratosphere extends up to 50km. The stratosphere consists of the ozone layer and is where Aerosols are mainly found and distributed.

What are the main characteristics that describes the Troposphere?

The troposphere is the layer of the atmosphere that we experience and so is where weather occurs and clouds form. 80% of the mass of the atmosphere is also contained in this layer and so its the densest air.

What does H20 do in the atmosphere?

absorbs and reflects solar radiation as well as absorbs infrared radiation that is emitted back from earths surface

3 of 6

How does CO2 act as a greenhouse gas? And what is it also responsible for?

It absorbs infrared radiation that the earth emits / reflects from its surface (so traps heat in the atmosphere). Its also responsible for the natural acidity of rain

4 of 6

What are Aerosols and what do they do?

A pollutant that is fine solid particles or liquid droplets which comes from combustion or volcanoes etc. It scatters and absorbs radiation

5 of 6

Why does temperature increase in three of the atmospheres layers...?(decrease in mesosphere)

Heat from the earths surface from infrared being emitted and solar radiation reflected, causing a warmer atmosphere in the troposphere. Then warming in the stratosphere due to the presence of the ozone layer (MORE), thermosphere = heat from sun
