Question

this image shows a model of the rock cycle. at point r, rocks melt underground to form magma. which is another process that contributes to the formation of rock at point r? compacting of sediments on the mountain cooling as the lava runs down the mountain weathering of the mountain from the environment eroding of different rocks at the base of the mountain

Explanation:

• Compacting of sediments forms sedimentary rock, which is not related to point R (magma - igneous rock formation).
• Weathering and erosion break down rocks and are not processes that contribute to the formation of rock from magma (at point R).
• When lava (which is magma that has reached the surface) cools, it forms igneous rock. Since point R is related to magma (which can become lava and then cool to form rock), cooling of lava (which is related to the magma at point R) is a relevant process.

Answer:

cooling as the lava runs down the mountain
