Study Notes
Sedimentary Rocks
- Formed from particles of broken rock and organic materials being pressed and cemented together.
- Common sediments include mud, sand, pebbles, shells, bones, leaves, and stems.
- Examples of sedimentary rocks: sandstone, limestone, and gypsum.
Sandstone
- A type of sedimentary rock formed by the compaction of sand particles.
Shale
- Composed of fine particles of clay and mud, making it a type of sedimentary rock.
Limestone
- A hard sedimentary rock primarily made of calcium carbonate or dolomite.
- Commonly used as a building material and in cement production.
Igneous Rocks
- Created from melted rock (lava) that cools and hardens.
- The term "igneous" derives from the Latin word for "fire."
Granite
- A light-colored igneous rock commonly found in the continental crust.
Quartz
- A mineral that is a component of igneous rocks.
- Used in the production of glass, electronic equipment, and watches.
Basalt
- A dark, dense igneous rock with a fine texture, typically found in oceanic crust.
Metamorphic Rocks
- Formed under heat, pressure, and chemical processes, usually occurring deep within the Earth's crust.
Slate
- A fine-grained metamorphic rock characterized by its dark gray color and ability to split into sheets.
Marble
- A hard metamorphic rock that originates from the alteration of limestone.
Graphite
- A form of black carbon frequently used for drawing or writing.
Mineral
- A solid inorganic substance composed of various elements.
- Essential for plant and animal survival, as they require a mixture of minerals.
