The document describes the rock cycle, which demonstrates the relationships between the three main rock groups - igneous, sedimentary, and metamorphic rocks. Igneous rocks form from cooling magma, either deep underground or at the Earth's surface. Sedimentary rocks form from the lithification of sediments at the Earth's surface. Metamorphic rocks form by subjecting existing rocks to heat, pressure, and fluids deep underground. The rock cycle is powered by Earth's internal heat and movements at the surface and interior through processes like weathering, erosion, deposition, and tectonic activity.

- 1. The Rock Cycle Thinking about relationships among the major rock groups
- 2. 2 Major Rock Groups • Igneous – Formed from a melt (molten rock) – Plutonic (intrusive):slow cooling and crystallization – Volcanic (extrusion): quick cooling at the surface • Sedimentary – Formed at the Earth’s surface – Clastic (Mineral Fragments or grains, clays) – Chemical (crystalline chemical/biochemical precipitates) • Metamorphic – Changed by pressure, temperature and fluids.
