Surface currents are on the of the Earth's oceans

1 answer:

6 0

Surface currents, which make up only 8% of all water in the ocean, are generally restricted to the upper 400 m (1,300 ft) of ocean water, and are separated from lower regions by varying temperatures and salinity which affect the density of the water, which in turn, defines each oceanic region.

organisms and water

Explanation:

Organisms and water contribute to both chemical and mechanical weathering . A form of weathering known as biological weathering is a derivative of both chemical and physical weathering.

Weathering is the physical disintegration and chemical decomposition of rocks to form sediments and soils.
Organisms are pivotal to both physical disintegration of rocks through their activities.
Through their metabolic activities, they also releases chemicals that are used for chemical weathering of rocks.

Water is essential for weathering. It is used in alternate freezing and thawing, a mechanical weathering process to break down rocks.

It is used in rock hydrolysis for chemical weathering.
