The Hydrosphere

In the topic of the Earth, also we are going to learn about THE HYDROSPHERE.

What is the hydrosphere?

The hydrosphere is all the water on Earth.

I would like to know how and where I can find water. Can you tell me?

WATER

LIQUID (covers most of the Earth's surface) is found in oceans, seas, rivers and lakes.
SOLID (snow and ice) is found in the polar regions and on mountains.
GAS (water vapor) is found in the atmosphere.

To get to know more about the hydrosphere, we will visit this webpage:

Lithosphere, Hydrosphere and Atmosphere

THE WATER CYCLE

Can you explain how the water cycle works? 

To answer this question, first of all we are going to watch this webpage. We will watch a video and test yourself.

Water cycle

Explain the picture which is below in pairs. (You can use the book page 28)

• (...) are the rise and fall of the sea level twice a day. They are caused by the gravitational pull of the Moon and Sun.
• (...) are the movements of large masses of ocean water in the same direction.

To remember we are going to make these activities:
