Online Glaciation Test

 

I have found an online glaciation test at:

The highest mark I have got so far is a B; if any one gets an A bring me proof and they will get a prize.

You may need to look up some of the key words in a dictionary as it is a bit more detailed than we need to know.

Formation of a Glacier

1. Precipitation (snow)

2. Fresh snow and ice starts to compact at the top of the glacier. Avalanches also occur at the top of the mountain.

3. Store - of ice

4. Flow - glacier moves downhill

5. Output - in the form of evaporated water or as melt water which runs off to flow into rivers / lakes etc…

Definitions:

• Moraine - material such as rocks and boulders that are transported by the glacier in the ice.
• Erratics - rocks and boulders transported by the glacier and deposited in an area of different rock. They can, therefore, easily be seen to be different from the rocks around them.
