We can tell a lot about the Earth's topography by viewing it from space.
"Topography" refers to a region's physical features, such as mountains, rivers,
volcanoes, and ice. Astronauts on board the Space Shuttle use a digital camera
called EarthKam to take pictures of the Earth's topography. Images from this
camera are available on the Internet for use by scientists and students a few
hours after they are taken.
