Question

How do erosion and deposition work together ?

Answer 1

Hint: Earth’s landforms keep changing. Erosion, deposition and weathering are the processes which change our earth’s landscape. They work over billions of years to tear down as well as build up earth’s surface.

Complete answer: To understand erosion, we have to first understand weathering. Weathering is the process by which rocks are broken down into smaller fragments and sediments.
-Erosion is the process by which these sediments are moved from one place to another. Gravity, running water, wind, waves are all agents of erosion. Moving water of rivers erodes rocks to form gorges and canyons. Wind carries sand and soil changing an area's landform. Gravity can also pull soil and rocks downhill.
-Deposition on the other hand, is the process of dropping of sediments that are carried by erosional agents like wind, water and gravity. Deposition of sand carried by wind forms sand dunes. Deposition of sediments carried by rivers form alluvial plains. This way erosion and deposition work together as deposition is followed by erosion.

Note: One must note that weathering is of three types- chemical weathering, biological weathering and physical weathering. Weathering and erosion differ from each other as erosion involves the movement of weathered fragments or sediments of rocks.
