Please help fast. Glaciers are formed by snow falling from the atmosphere on a place such as Alaska, where it does not melt. More and more snow falls and becomes compacted over a period of time to make a glacier.

A glacier that moves seven miles per year is considered a very rapidly-moving glacier. Different parts of a glacier may move along at different rates of speed.
How do Earth’s spheres interact when a glacier moves across its surface? Name three spheres and give examples of interactions.
