Learning Objective
I can describe how glaciers and tectonic plates shape Earth's surface and how this dictates where cities are located.
- 1
A glacier is a large mass of ice that formed from compressed snow that moves due to its own weight and the pull of gravity.
- 2
Glaciers covered in snow reflect a lot of the solar radiation they get, which helps keep the Earth cool.
- 3
Moraines and erratics are depositional features formed from the debris carried by ice as glaciers melt, and they influence how the land is used today.
