In This Lesson:
Water bodies on Earth have different forms and locations such as :

- They are very large water bodies.
- Oceans and seas always contain salt water.


- A lake is a water body that is surrounded by land.
- Lakes are often contain fresh water, but sometimes they contain salt water.


- A river is a water body that always flows from an area of high altitude (high place) to an area with lower altitude (lower place) in a definite path..
- Rivers always contain fresh water.

It is the water that lies beneath (under) the Earth's surface.

Is water a renewable resource?
1. Water present in water bodies on Earth
evaporates.
2. Water vapor collects in the air, forming clouds.
3. Water returns back to the Earth's surface
in the form of rains.
So, the percentage of water is constant on Earth

Why are plants considered renewable resources?
• Because plants can be planted from seeds that grow up forming new plants.
• Plants depend on water to grow and survive, so plants are affected if the amount of water decreases, or water get polluted.
