Exploratour - The Surface of the Earth
At both poles there are deep areas of snow, ice, and glaciers. In fact, the continent of Antarctica is buried in about 10,000 ft of ice.
The polar caps are part of the water cycle. The term water cycle describes the way water flows and is recycled from the land to the oceans and back again.
This is an image of Antarctica taken by the Galileo spacecraft.

Exploratour - The Surface of the Earth
Once again, viewing our rotating globe from the first page of the tour, you can see deep folds along the ocean floor. The deepest places on Earth are along these deep folds. The very deepest spot on Earth is deeper than the highest peak. The lowest spot on the ocean floor is 35,000 ft, while the highest spot, Mt. Everest, is 29,000 ft.
On the ocean floor there are:
-
deep trenches at the edges of some plates
- raised areas in the middle
- transform faults
- large volcanoes which form isolated islands
Find some of these spots for yourself.
In this image find subduction trenches, island arcs, and mid-ocean ridges.
