Study Notes
Weathering
- Weathering involves the physical and chemical breakdown of rocks.
- Physical weathering occurs through natural processes, leading to fragmentation without altering mineral composition.
- Chemical weathering involves chemical reactions that alter the minerals within rocks, such as the reaction of water and air with rock minerals.
Examples of Weathering
- Sudden temperature changes can exemplify physical weathering, leading to cracks and breaking of rocks.
- Chemical weathering can occur when water or air interacts with rock minerals, leading to chemical alterations.
Types of Rocks
- Limestone is a rock consisting primarily of one mineral.
- Granite is a rock that incorporates multiple minerals, showcasing its complexity.
Crystals
- Diamonds, Rubies, Sapphires, and Emeralds are examples of naturally occurring crystals.
Rock Cycle
- The rock cycle illustrates the transformation of magma into igneous rocks, sedimentary rocks, and metamorphic rocks before returning to magma.
Erosion
- Erosion is the process where weathered materials are transported by wind, water, or glaciers.
Rock Types
- Igneous rocks form from the cooling or hardening of magma or lava.
- Sedimentary rocks arise from the cementing and hardening of sediments.
- Metamorphic rocks originate from existing rocks transformed by heat and pressure.
Minerals
- Minerals are naturally occurring substances in the Earth and serve as the fundamental building blocks of rocks.
- Ores are minerals or rocks from which metals can be extracted.
Igneous Rock Subtypes
- Volcanic igneous rocks are formed on or near the Earth's surface.
- Plutonic igneous rocks are formed beneath the Earth's surface, typically resulting in a different texture.
Rock Examples
- Basalt serves as an example of volcanic rock.
- Granite is categorized as a plutonic rock, often characterized by its coarse grain.
