Here's a breakdown:
* Igneous Rocks: Formed from the cooling and solidification of magma (molten rock) or lava.
* Sedimentary Rocks: Formed from the accumulation and cementation of sediments (like sand, silt, or shells).
* Metamorphic Rocks: Formed when existing igneous or sedimentary rocks are transformed by heat, pressure, or chemical reactions.
The rock cycle illustrates how these three rock types are interconnected and constantly change over time through processes like:
* Weathering and Erosion: Breaking down rocks into smaller pieces (sediments) and transporting them.
* Deposition: Sediments settling in a new location.
* Compaction and Cementation: Sediments are pressed together and glued together to form sedimentary rocks.
* Melting: Rocks melt to form magma.
* Crystallization: Magma cools and solidifies to form igneous rocks.
* Metamorphism: Existing rocks are altered by heat and pressure.
It's a continuous cycle where rocks are constantly being created, destroyed, and transformed.
