Plucking

Explanation:

Glacial erosion, the picking up and movement of earth beneath a glacier, is also known as plucking. Plucking occurs in "valley glaciers." First, the bottom part of the glacier melts due to the friction generated by the movement of the glacier. This allows ice to infiltrate cracks in the bedrock. As this ice freezes and thaws, it causes further cracks, gradually loosening the rocks. The rocks become trapped in the glacier, leading to erosion.

c. seafloor spreading occurs.

d. crust becomes molten rock.

e. denser plates slide under lighter plates.

a mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. this uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.a geomagnetic reversal is a change in a planet's magnetic field such that the positions of magnetic north and magnetic south are interchanged.
