Running water, like rivers and streams, affects the land in three ways: Erosion, Transportation, Deposition.
Rivers and streams erode land as they move from higher elevations to the sea. They transport weathered materials, such as minerals that dissolve easily in water. As a stream nears the ocean, it deposits more materials than it erodes.
Some of the deposits left behind by rivers and streams include: Natural levees: Built along the banks of a stream after many floods Meander deposits: Found along the inside edges of meanders The material deposited by streams is called alluvium.
Running water is considered the most important geological agent.
The geological work of the sea includes:
Continental shelf: A gently sloping land part that is partially submerged by seawater Continental slope: A slope that starts at the ocean floor's farthest end and continues up to the ocean floor Seafloor spreading; A geological process that occurs in the ocean due to divergent plate tectonics Erosion: A geological process that wears away and rebuilds earth and its landforms through the natural forces of water and wind Deposition; The erosive work of the sea depends upon the wave exerts a pressure to the magnitude of 3000 to 30,000 kilograms per square kilometre
