Grade 10 Science

2. Cryosphere
The cryosphere consists of all the frozen water on the Earth’s surface.

3. Pack Ice
Pack ice is composed of the ice floating on the oceans near the North and South poles.

4. Melting Pack Ice

5. Glaciers
A glacier is a mass of ice on land, formed by compressed snow.

7. Compressed snow turns to ice

8. Icebergs

14. Glaciers and pack ice melting
Impacts:
Sea levels rise due to glacier melting
Affects thermohaline ciculation
Fresh water is released from glaciers  mixes with the Gulf stream density of water decreases  water does not sink  ocean currents slow (but will not stop)
