Question

1 multiple choice 1 point which process forms igneous rocks? compaction and cementation melting and cooling of magma or lava weathering and erosion heat and pressure 2 multiple choice 1 point what can break down rocks into sediments? compaction and cementation melting and cooling of magma or lava weathering and erosion heat and pressure

Explanation:

1. Igneous rocks are formed from the cooling and solidification of magma or lava. Compaction and cementation form sedimentary rocks, weathering and erosion break down rocks, and heat and pressure form metamorphic rocks.
2. Weathering and erosion are processes that break down rocks into smaller pieces called sediments. Compaction and cementation turn sediments into sedimentary rocks, melting and cooling form igneous rocks, and heat and pressure form metamorphic rocks.

Answer:

1. Melting and cooling of magma or lava
2. Weathering and erosion
