Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Erosion and deposition constantly change Earth’s surface. Erosion carries natural materials like rock and soil from one place to another. Through deposition, these natural materials may be deposited in areas where they build up over time. Which landform results from the deposition of materials in a valley during volcanic eruptions?
A
sill
B
mud pot
C
caldera
D
lava plateau
Explanation: 

Detailed explanation-1: -Answer. Answer: The material moved by erosion is sediment. Deposition occurs when the agents (wind or water) of erosion lay down sediment.

Detailed explanation-2: -Earth’s surface is constantly changed by erosion and deposition. Erosion breaks down Earth’s surface by carrying materials away from an area. Deposition builds up Earth’s surface when these materials are deposited in an area over time.

Detailed explanation-3: -Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water.

Detailed explanation-4: -Sediment is created through the process of weathering, carried away through the process of erosion, and then dropped in a new location through the process of deposition. When wind and water slow down, they drop the sediments they are carrying.

Detailed explanation-5: -The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.
