Many things can break rocks into smaller particles and move them around. What changes rocks into large, U-shaped valleys?
A
glaciers
B
heavy rain
C
strong winds
D
winding rivers
Explanation: 

Detailed explanation-1: -Erosion is the process where rocks are broken down by natural forces such as wind or water.

Detailed explanation-2: -Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion.

Detailed explanation-3: -Erosion and weathering include the effects of wind and rain, which slowly break down large rocks into smaller ones. Erosion and weathering transform boulders and even mountains into sediments, such as sand or mud.

Detailed explanation-4: -Rocks break down by the process called weathering. Moving water, wind, and glaciers then carry these pieces from one place to another. This is called erosion.

Detailed explanation-5: -Surface area–if the rock is broken down into small pieces, it undergoes chemical weathering more readily than does one large piece. Smaller pieces have more surface area for water and gases to react with the rock. Mechanical weathering is effective at increasing surface area.
