4. 4. What is snowpack?

Open Ended

5. 5. Why is snowpack important?

Snowpack is important because it provides water to streams, rivers, lakes and reservoirs; gradually it melts.

As the world gets warmer, many mountain areas have less snowpack than they used to and this affects the amount of drinking water that is available to people who live there.

​Less snowpack.

5. 5. Name this picture.

Warmer temperatures causing glaciers to melt.

The faster the glaciers and the giant ice sheets melt, the more water is added to the oceans.

This causes the sea level around the world to rise.

6. 6. What happened to the sea levels if there is an increase of rainfall and the melting of glaciers?

The increased rainfall in some areas as well as the melting of glaciers has caused the sea levels to rise.

Rising sea levels.

7. 7. What caused the sea level to rise up?

​​Warming oceans.
It can kills many kinds of sea life, such as corals and fish.

​Changing snow fall and rain patterns.

As temperatures rise and the air becomes warmer, more moisture also evaporates from land and water into the atmosphere.
More moisture in the air leads to more precipitation, heavy rain and snow fall.
Some places get less precipitation, some become hotter and dryer and some tend to become colder and wetter.
