Description:

In this unit we are going to focus on Earth's water resources:

1.	Learn about the largest feature on planet Earth, its water:
		The Physical features of water. The water cycle on Earth. Learn about the different fresh water sources on Earth.
2.	Learn about the largest source of water on Earth, its oceans:
		Examine how oceans affect Earth's weather. Look at ocean waves. Learn about the affects of the moon and tides. How the oceans affect seasons and climate.

In the image at right you can see Earth's largest feature its oceans. Most of Earth's fresh water comes from the water cycle in which ocean water evaporates into the clouds and then falls back to the Earth in the form of rain. Rain can then flow back into the oceans as runoff which completes the cycle and allows water to cycle through the process again.
