Humans and all other life forms live within Earth’s

• troposphere

• stratosphere

• mesosphere

• thermosphere

• atmosphere

Also known as topography - occurs when air is confronted by mountains, it cannot simply go through them. As the air ascends the mountain, the air cools as it rises and if it cools to its saturation point, the water vapor condenses and a cloud forms.

• convergence

• convective lifting
