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:

At point R, rocks are melting to form magma underground. Cooling of lava as it runs down the mountain can contribute to rock - formation processes related to the rock cycle near the volcanic area. Compacting of sediments forms sedimentary rocks in different locations, weathering breaks down rocks and eroding moves rock particles away, none of which directly contribute to rock formation at the magma - forming point R.

Answer:

cooling as the lava runs down the mountain
