Large potholes were formed by swirling vortexes of water called kolks scouring and plucking out the bedrock. [10] The Scablands are littered with large boulders called glacial erratics that rafted on glaciers and were deposited by the glacial outburst flooding. The lithology of erratics usually does not match the rock type that surrounds it, as ...
The Ogallala Aquifer (oh-gə-LAH-lə) is a shallow water table aquifer surrounded by sand, silt, clay, and gravel located beneath the Great Plains in the United States. As one of the world's largest aquifers, it underlies an area of approximately 174,000 sq mi (450,000 km 2) in portions of eight states (South Dakota, Nebraska, Wyoming, Colorado, Kansas, Oklahoma, New Mexico, and Texas).

Water tends to be stagnant or may flow slowly on a seasonal basis. [5] In North America, "slough" may refer to a side-channel from or feeding a river, or an inlet or natural channel only sporadically filled with water. [3] An example of this is Finn Slough on the Fraser River, whose lower reaches have dozens of notable sloughs.
Interfluve – Land between two converging, or confluent, rivers, mainly in the Punjab; Inverted relief – Landscape features that have reversed their elevation relative to other features; Island – Piece of subcontinental land completely surrounded by water; Islet – Very small island
Oceanic eddies are also usually made of water masses that are different from those outside the eddy. That is, the water within an eddy usually has different temperature and salinity characteristics to the water outside the eddy. There is a direct link between the water mass properties of an eddy and its rotation.
Rotating masses of water called eddies are common in the ocean. The newly revealed pairs, however, churn through the water up to ten times faster than their single counterparts, and are connected ...
Plunge pools are often very deep, generally related to the height of the fall, the volume of water, the resistance of the rock below the pool and other factors. [4] The impacting and swirling water, sometimes carrying rocks within it, abrades the riverbed into a basin, which often features rough and irregular sides. Plunge pools can remain long ...
Also actiniform. Describing a collection of low-lying, radially structured clouds with distinct shapes (resembling leaves or wheels in satellite imagery), and typically organized in extensive mesoscale fields over marine environments. They are closely related to and sometimes considered a variant of stratocumulus clouds. actinometer A scientific instrument used to measure the heating power of ...
