Question

question 3.
which process in the rock cycle does this diagram best represent?
a. chemical weathering of rocks
b. erosion of sedimentary rocks
c. compaction of melted rock
d. formation of igneous rock

Explanation:

The diagram shows magma rising at a divergent oceanic plate boundary, where magma cools and solidifies to form rock. Chemical weathering (A) and erosion (B) involve breaking down existing rock, not forming new rock from magma. Compaction (C) is part of sedimentary rock formation, not magma-based rock formation. Igneous rocks form when magma or lava cools and solidifies, which matches the process shown.

Answer:

D. formation of igneous rock
