The Water Cycle Flashcards
1

The movement of water around the world.
2
Q
Steps of the water cycle?
A
- Suns energy evaporates water, turning into water vapour and plants by transpiration
- Carried upwards , cools and condenses to make clouds
- Falls as precipitation onto land, provides water for plants and animals.
- Eventually drains to the sea
3
Q
What is a drought?
A
Lack of water fought by potable water by desalination.
4
Q
What is desalination?
A
Removal of salt from sea water by thermal desalination. This is where water is boiled and salt is left behind. We obtain pure water.
5
Q
How to desalination other than distillation?
A
Reverse osmosis is used when it’s from a low to high concentration as the salt water is a high solution so by removing the solids first then putting the solution through a high pressure vessel this pressure causes water to move opposite direction to osmosis this leaves water without salt
