Major continental divides, showing drainage into the major oceans and seas of the world. Grey areas are endorheic basins that do not drain to the ocean.. A continental divide is a drainage divide on a continent such that the drainage basin on one side of the divide feeds into one ocean or sea, and the basin on the other side either feeds into a different ocean or sea, or else is endorheic, not ...
Most lakes are not actually endorheic, but endorheic basins may not have standing water, or have water only seasonally. The most significant endorheic basins are these: Great Basin covering most of Nevada, the western part of Utah, and smaller amounts of other U.S. states; Great Divide Basin on the Continental Divide in Wyoming; Guzmán Basin
Kentucky that the state line is the low-water mark of the Ohio River's north shore as of Kentucky's admission to the Union in 1792. [2] Because both damming and natural changes have rendered the 1792 shore virtually undetectable in many places, the exact boundary was decided in the 1990s in settlements among the states.

Maps exhibiting the world's oceanic waters. A continuous body of water encircling Earth, the World/Global Ocean is divided into a number of principal areas. Five oceanic divisions are usually recognized: Pacific, Atlantic, Indian, Arctic, and Southern/Antarctic; the last two listed are sometimes consolidated into the first three.
The terms international waters or transboundary waters apply where any of the following types of bodies of water (or their drainage basins) transcend international boundaries: oceans, large marine ecosystems, enclosed or semi-enclosed regional seas and estuaries, rivers, lakes, groundwater systems , and wetlands.

The process of creating an "impoundment" of water is itself called "impoundment". Ice cap: A body of frozen water less than 50,000 km 2 not constrained by topographical features (i.e., they will lie over the top of mountains) Ice field: A body of frozen water constrained by topographical features: Ice sheet: A body of frozen water more than ...
In summer 1965, the first close-up images from Mars showed a cratered desert with no signs of water. [1] [2] [3] However, over the decades, as more parts of the planet were imaged with better cameras on more sophisticated satellites, Mars showed evidence of past river valleys, lakes and present ice in glaciers and in the ground.
