What are four factors that cause rocks to change types?

Rocks can change types due to processes such as weathering and erosion, which break down existing rocks into sediment. These sediments can then be compacted and cemented to form sedimentary rocks. Additionally, metamorphism occurs when rocks are subjected to high pressure and temperature, transforming them into metamorphic rocks. Lastly, volcanic activity can melt rocks into magma, which can cool and solidify into igneous rocks.
