Weathering, Erosion, and Deposition

What is a delta? Explain how weathering, erosion, and deposition work together to form a delta. Be SPECIFIC

A delta us a fan shaped area of land formed by the build up of sediments at the mouth of a river, where it empties into a ocean. To form a delta first weathering has to break down rock into sediments, then erosion moves it to the mouth of a river, where it empties into the ocean, finally deposition deposits the sediments building up a delta.

Define a oxbow lake and meanders and explain how they are related.

A oxbow lake is a meander that was cut off by a new channel and is now separated this usually happens in a flood and a meander is a curve in a stream. These two are related because without a meander there would be no oxbow lake

Compare and contrast chemical and physical and chemical weathering. Include one way they are the same and two ways they are different.

Chemical: The rocks composition changes Breaks down the rocks through chemical reaction. Physical: The rocks composition does not change Breaks down rocks with physical force Both: Breaks down rocks to form sediments

What is deposition?

Deposition is the process in which sediment is placed, or deposited in a new location.

What is erosion? what process forms the particles that are involved in erosion?

Erosion is the process in which sediments are picked up and moved from one place to another. Weathering is the process that breaks down rocks to sediments that are then moved by erosion.

What is the main force that causes erosion and deposition?

Gravity is the main force that causes erosion and deposition.

What are the three agents of erosion?

The three agents of erosion are ice, wind, and water.

What is weathering? What are the two main types of weathering?

Weathering is the force by which natural forces break down rocks. The two main types of weathering are chemical and physical weathering.
