Glaciers & icerbergs?

Question

1. How do glaciers erode the land?

2. Where are two placces continental glciers are found.

And some help with this: is 10% of an iceberg is above water and it's 70ft. How much is underwater?

Thanks!

Answer 1

As glaciers move down the landmass their enormous weight uses trapped boulders, sand, rock and other debris to scour the land.  Runoff also can cause erosion.

Continental glaciers are found in and around the Arctic, Antarctic circles, Greenland and islands in the polar regions.

Iceberg is 70 feet.  70 times 10% = 7 feet.  Consequently, ergo, thus, hence 70-7=63 feet below water.
