Soil moisture is the water that is held in the spaces between soil particles, generally in the upper 10 cm of soil; this small amount of water plays a critical role in controlling the transfer of water and heat energy between Hydrosphere, Biosphere, and Geosphere.

In some parts of the world sea levels are increasing, while decreasing in others, and even remain relatively flat in a few places; for more than 20 years, NASA has been tracking the global surface topography of the ocean to understand the important role it plays in our daily lives. 

This learning activity uses data acquired by the TOPEX/Poseidon altimeter, a joint project of NASA and the French Space Agency, to investigate the relationship between the topography of a sea-floor feature and the topography of the overlying sea surface.

This activity is designed to introduce students to geologic processes on Earth and how to identify geologic features in images. It will also introduce students to how scientists use Earth to gain a better understanding of other planetary bodies in the solar system. 

In this activity, you will use satellite images from the NASA Landsat team to quantify changes in glacier cover over time. This lesson utilizes change pair images of Bear Glacier in Kenai Fjords National Park, located on the southeastern portion of Alaska’s Kenai (pronounced: Key-nigh) Peninsula,
