As shown in this composite, clouds often form just over the land or just over the water, and can be indicators of surface features or near-surface processes. The top left image is a high oblique view of clouds over water. The Earth limb (a) shows the thickness of atmosphere. The top right image is of clouds over Trinidad (b). Clouds have formed only over the land through the combined actions of transpiration (the release of moisture through leaves) from the trees and the uplift of air over the islands. The bottom left image is of clouds along the Amazon River (c). Transpiration from the heavy vegetation growth in the Amazon basin provides the trigger for cloud formation over the land but not over the river. Regions that have been cleared of forest generally have fewer clouds. Finally, the bottom right image is of coastal fog along Namibia (d). Where the cool waters off the southwest coast of Africa meet the warm land, low stratus clouds form. Occasionally this fog drapes inland a small distance, providing the only moisture to this desert region.

Transcription Notes:
I know image descriptions aren't needed but there is a lot of text surrounding the images so I added it here just in case.
