Ni`ihau, Kaua`i, O`ahu, Moloka`i, Lanai, Kaho`olawe, Maui, and Hawai`i are the main inhabited islands of the Hawaiian Archipelago.
A basin is a depression, or dip, in the Earth’s surface.
Deltas are found on the lower reaches of rivers, where the flow of water spreads out and slows down, depositing sediments into expanses of wetlands and shallow water.

Deserts cover more than one fifth of the Earth's land, and they are found on every continent.

Find animations and movies revealing how a glacier forms, moves, retreats, and in the case of tidewater glaciers, calves. Images of glaciers are also available.
Glaciers, of all our alpine landforms, have had more visual impact on our landscape than any erosional agent, save water.
Matagorda Island, located on the mid-Texas coast in Calhoun County, is about 38 miles long and averages Matagorda Island is very important in United States and Texas history. It is also important about 1 1/2 miles in width.
