Explanation:

Question 1

The rock cycle is a continuous process by which rocks are formed, broken down, and transformed into different types (igneous, sedimentary, metamorphic) through geological processes like melting, cooling, erosion, deposition, compaction, cementation, and metamorphism.

Igneous rocks form from the cooling and solidification of magma (molten rock below the Earth's surface) or lava (molten rock above the surface). The key processes are melting of rock to form magma, followed by cooling (either intrusively, slowly underground, or extrusively, quickly at the surface) and crystallization.

Sedimentary rocks form from the accumulation and lithification of sediment. The key processes are erosion (breaking down of rocks into particles), transportation (moving sediments via water, wind, etc.), deposition (sediments settling in layers), compaction (pressure from overlying layers reducing pore space), and cementation (minerals binding sediments together).

Answer:

The rock cycle is a series of natural processes that transform one type of rock (igneous, sedimentary, metamorphic) into another through events like melting, cooling, erosion, deposition, compaction, cementation, and metamorphism.
