Answer

Brief Explanations:

Magma is molten rock beneath the Earth's surface. It forms when solid rock melts due to high - temperature and pressure conditions in the Earth's mantle or crust. Compaction and cementation form sedimentary rocks, deposition is related to the accumulation of sediments, and weathering and erosion break down rocks but do not directly form magma.

Answer:

From melting rock
