Explanation/Hydrosphere/Draft

Did you know the hydrosphere includes all the water on Earth. The range of surface temperatures and pressures of our planet allow water to exist in all three states: solid (ice), liquid (water), and gas (water vapour). ... Over the past one million years the earth has gone through periodic glacial and interglacial cycles.

HYDROSPHERE

1st Paragraph

the water cycle of processes by which water circulates between the earth's oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration. The water or hydrolic is a continues cycle where water evaporates. Water keeps moving and changing from a solid to a liquid to a gas, over and over again.

2nd paragraph

Saltwater is denser than fresh water because of its salt content. There is 3% of fresh water and 95% of salty water. Saltwater is made when freshwater moves over land. Saltwater is denser than freshwater so will sink below the freshwater.

3rd paragraph

A hydrosphere is the total amount of water on a planet. The hydrosphere includes water that is on the surface of the planet, underground, and in the air. A planet's hydrosphere can be liquid, vapour, or ice. On Earth, liquid water exists on the surface in the form of oceans, lakes and rivers. It also exists below ground—as groundwater, in wells and aquifers. Water vapour is most visible as clouds and fog. The frozen part of Earth's hydrosphere is made of ice: glaciers, ice caps and icebergs. The frozen part of the hydrosphere has its own name, the cryosphere. 

Conclusion: 

I love the way I learned about hydrosphere and I would like to learn about the 4 spheres because they are very interesting.
