the water cycle Flashcards
1
Q
describe the water cycle
A
- energy from the sun makes water evaporate from the land and sea, turning it into water vapour, water also evaporates from plants via transpiration
- the warm water vapour is carried upwards (as warm air rises). when it gets higher up it cools and condenses to form clouds
- water falls from the clouds as precipitation onto land, where it provides fresh water for plants and animals
- it then drains into the sea, before the whole process starts again
