The answer is terracing

Explanation:

Terracing here can be described as a process of carving or cutting out flat surface areas from slopes like hills, mountains for farming purposes. This helps to prevent soil erosion and flooding. It also helps to retain soil moisture.

c. seafloor spreading occurs.

d. crust becomes molten rock.

e. denser plates slide under lighter plates.

the answer would be the third option, "no, ariel should have added 9^2 and 12^2 and compared that to 15^2."

this is found through the pythagorean theorem, which is a^2 + b^2 = c^2.

this is the correct way of solving the problem:

9^2 + 12^2 = 15^2

81 + 144 = 225

225 = 225
