deep zone
This is the removal of soil by runoff from the land surface whereby numerous small channels, generally up to 30 cm deep are formed...................................................................................Or.......................... Rill Erosion: This is the flow of run off water causes concentrated channels,to be formed at the surface of the soil.
A salt and water, generally.
Deep ocean currents are formed by differences in water temperature and salinity, as well as by the topography of the ocean floor. Cold, dense water sinks and flows along the bottom of the ocean, while warm water rises and flows along the surface, creating a continuous circulation pattern. This movement of water is also influenced by the rotation of the Earth and wind patterns.
A deep current is found in the ocean when a temperature change occurs. This also has to do with the alignment of the sun and the moon.
You may be thinking of a fjord (or fiord), a narrow, deep inlet (generally in a coastal landscape) formed by glacial activity.
Generally, diamonds are formed in the Earth and not from Supernovas.
A canyon is a deep, narrow valley with steep sides typically formed by erosion, while a hill is a raised area of land that is higher than the surrounding landscape but generally not as steep or deep as a mountain. Canyons are typically the result of water erosion over time, while hills can be formed by a variety of geological processes.
Glacier movement has formed various bodies of water, including fjords, lakes, and rivers. When glaciers advance and retreat, they carve out deep valleys that can fill with water to create these different water bodies.
Caves are generally formed in areas rich in limestone, which erodes as water flows over it over time.
These are generally called "Natural Harbors"
