Question

the diagram below shows the basic materials and processes involved in the rock cycle. which of the following processes within the rock cycle operates at the earths surface? a. melting b. weathering c. plate tectonics d. pressure & heat

Explanation:

Weathering is a surface - level process where rocks are broken down by natural forces like wind, water, and temperature changes at the Earth's surface. Melting, plate tectonics (which mainly occur in the Earth's interior in the context of rock - cycle processes relevant here), and pressure & heat typically occur beneath the Earth's surface.

Answer:

B. weathering
