Answer:
Mechanical weathering
Explanation:
Weathering is defined as the process by which rock materials are broken down by the action of physical or chemical processes. Physical weathering is known as mechanical weathering, where rocks breakdown into smaller pieces by mechanical means.
Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away

B. The natural channel had a lower gradient and higher friction than the straight channel.
An Isosceles triangle has two even parts, you add them up. For example 60 degree plus another 60 degree angle is 120 degrees. And the limit is 180 degrees, so in order to get that last angle, you'd have to subtract 160 from 180. And that'd be 20 degrees. I couldn't see the question but I hope this helps you in a way
