UNIT 3: THE EARTH´S HYDROSPHERE
In this unit you will understand the water cycle and also about the oceans and seas.
We will learn about continental waters, such as glaciers, rivers, lakes and groundwater.
We will try to understand that water is a vital resource for us all.

This first introductory video is about the Hydrosphere and the future of it in relationship with the climate change and the use we do of water. Nice music and true words...
Have a look at it!!!
