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? eroding of different rocks at the base of the mountain weathering of the mountain from the environment cooling as the lava runs down the mountain compacting of sediments on the mountain

Explanation:

At point R, rocks melt underground to form magma. Magma forms through melting of rocks due to high - temperature and pressure conditions. Eroding of different rocks at the base of the mountain is related to surface processes, weathering of the mountain from the environment is a surface - altering process, and cooling as lava runs down the mountain is related to the solidification of magma after it has erupted. Compacting of sediments on the mountain is related to sedimentary rock formation. The process that contributes to the formation of rock at point R is the melting of rocks to form magma.

Answer:

compacting of sediments on the mountain
