Glaciers were formed back in the last ice age 2.6 million-12,000 years ago

3

Where can you find glaciers?

You can find a glacier anywhere
Usually most glaciers are found further away from the equator,(e.g. The Lambert Glacier in Antartica)some can be found closer to the equator(e.g. The Kilimanjaro Glacier).

4

How do glaciers erode?

Glaciers erode through a process called Freeze-Thaw weathering where they pluck debris off of the surface

5

What is Freeze-Thaw weathering?
How does it work?

Freeze-Thaw weathering is another way glaciers erode
During the day, water goes into the cracks of rocks and expands. During the night, it contracts. The water will do this for a while,(maybe a year) and after a period of time, it will wear down the rocks enough and the rocks will the break. The Glacier then plucks the rock up and drags it along with it.
