Question

the processes in the rock cycle create, destroy, or change rock. these processes are driven by energy. for example, rock can gain or lose thermal energy due to the flow of heat. if solid rock gains enough thermal energy, the rock will melt. if melted rock loses enough thermal energy, the rock will crystallize. the examples below describe processes in the rock cycle. select the two processes that directly depend on changes in thermal energy. a landslide moves sediment downhill. lava crystallizes to form igneous rock. rock reaches a high - enough temperature to melt.

Explanation:

1. Analyze "A landslide moves sediment downhill": This is driven by gravity, not thermal energy changes.
2. Analyze "Lava crystallizes to form igneous rock": Lava (melted rock) loses thermal energy to crystallize, so this depends on thermal energy change.
3. Analyze "Rock reaches a high - enough temperature to melt": Rock gains thermal energy to melt, so this depends on thermal energy change.

Answer:

B. Lava crystallizes to form igneous rock, C. Rock reaches a high - enough temperature to melt
