What is terrigenous sediment?

A:

Quick Answer

Terrigenous sediments are marine sediments typically formed by the weathering and erosion of igneous and metamorphic rocks. Rivers are a major factor in the transportation of these sediments.

Full Answer

Terrigenous sediments are typically formed due to chemical weathering and dissolving of rocks. Some physical weathering occurs as a result of a region's climate. When the rocks are broken down by either process, they can then be transported. Transportation of terrigenous sediment is most commonly performed by rivers.

Gravity and wind both cause terrigenous sediments to be displaced from their original position and to form as marine sediments. Build-up of the sediments near oceans may cause them to become unstable and slide, allowing for deeper deposition into the water. Materials such as clay are deposited deeper into oceans than other particles.
