Question

according to the rock cycle, select all of the following steps that are possible. assume an unlimited number of steps. a metamorphic rock becomes an extrusive igneous rock. an intrusive igneous rock becomes a sedimentary rock. a sedimentary rock becomes soil.

Explanation:

1. For "A metamorphic rock becomes an extrusive igneous rock": Metamorphic rocks can melt into magma (due to heat/pressure), and then the magma can erupt (extrude) onto the Earth's surface and cool to form extrusive igneous rock. So this is possible.
2. For "An intrusive igneous rock becomes a sedimentary rock": Intrusive igneous rocks (formed underground) can be exposed at the surface through processes like erosion/tectonic uplift. Then, they can undergo weathering, erosion, deposition, compaction, and cementation to form sedimentary rock. So this is possible.
3. For "A sedimentary rock becomes soil": Sedimentary rocks can be weathered (physical, chemical, biological weathering) into smaller particles, which along with organic matter and other components, form soil. So this is possible.

Answer:

A. A metamorphic rock becomes an extrusive igneous rock
B. An intrusive igneous rock becomes a sedimentary rock
C. A sedimentary rock becomes soil
