Mountains Shaped by Volcanic Activity
While the creation of mountains and other land formations can take millions of years, the changing shape can be seen in active volcanoes. This video shows dome growth of Mount St. Helens from 2004 to 2008.

Eroding Rivers
This image shows a meandering river change its shape as it cuts into the land. It can be seen that oxbow lakes are created when a cutoff redirects the river into a shorter path. This image was created using Google's Earth Engine, which you can explore below.

Sea Level During Glacial Periods
This image shows the Bering Land Bridge during the last glacial period. As the climate warmed, glaciers and ice sheets melted, which in turn raised sea levels and removed this land bridge.

Glaciers
The following videos show the movement of glaciers. Because glaciers move slowly, time-lapse photography is needed to see them move. These videos were made by the Extreme Ice Survey, and you can see more here.

This video shows the much wider Columbia Glacier in Alaska. It can be seen that this glacier is retreating quickly.

This video shows a part of the glacier breaking off the edge, called ice calving.

This video shows the largest calving of a glacier ever caught on film. This segment is from the award-winning documentary Chasing Ice.
