Study Notes
Types of Rocks
-
Granite: Rich in alkali feldspar; commonly used in construction due to durability and aesthetics.
-
Basalt: Magnesium- and iron-rich; a dense volcanic rock that is often dark in color and forms from rapid cooling of lava.
-
Rhyolite: Volcanic rock characterized by a crumpled appearance, indicating a highly viscous molten state before solidification.
-
Gabbro: Mafic intrusive rock mainly composed of plagioclase, as well as pyroxene and sometimes olivine; forms from slow cooling of magma beneath the Earth's surface.
-
Obsidian: A type of volcanic rock known for its glassy texture and typically dark color, formed from rapidly cooled lava.
Additional Information
-
Sedimentary Rocks: Not primarily mentioned, but are formed through the accumulation of sediments, differentiated from the discussed igneous rocks.
-
Importance of Rock Types: Understanding rock types aids in geology, construction, and resource identification.
