Types of Rocks - Geology Page

Mar 20, 2017· There are two basic types: Intrusive igneous rocks crystallize below Earth's surface, and the slow cooling that occurs there allows large crystals to form. Examples of intrusive igneous rocks are diorite, gabbro, granite, pegmatite, and peridotite. Extrusive igneous rocks erupt onto the surface, where they cool quickly to form small crystals.

Three Types of Rock: Igneous, Sedimentary & Metamorphic | …

Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers. Metamorphic rocks result when existing rocks are changed by heat, pressure, or reactive fluids, such as hot, mineral-laden water. Most rocks are made of …

5 Chemical Weathering Examples and How They Occur

Hydration is a type of chemical weathering where water reacts chemically with the rock, modifying its chemical structure. One example of mineral hydration is when H 2 O (water) is added to CaSO 4 (calcium sulfate) to create CaSO 4 + 2 H 2 O (calcium sulfate dihydrate). It changes from anhydrite to gypsum.
