The answer is B. In a destructive plate boundary, the descending plate, usually the oceanic plate begins to melt as it descends below into the mantle. This forms magma that rises and erupts onto the overlying continental plate through fissures.

Abundant moisture and warm temperatures result in high rates of chemical weathering.
Chemical weathering is due to rainwater reacting with the mineral grains in rocks to shape new minerals (clays) and soluble salts. these reactions arise especially while the water is slightly acidic.
Weathering breaks matter down into smaller portions. The motion of pieces of rock or soil to new places is known as erosion. Weathering and erosion can cause adjustments to the form, length, and texture of different landforms (together with mountains, riverbeds, seashores, and so forth).
The most important element of weathering is its role in the formation of soil. with out soil, existence, as we realize it on the earth, might not exist. Soil is a miles unnoticed element of earth's strategies and, at contemporary rates of human use and abuse, is becoming a finite useful resource.
