How are are some rocks formed and what are their charateristics?
Metamorphic rocks are formed when existing rocks are undergo high temperature and pressure without melting.
Igneous, sedimentary, and metamorphic rocks are all composd of minerals as their fundamental building blocks.
Foliation is a characterstic feature of metamorphic rocks, resulting from the alignment of minerals under pressure during metamorphism.
Melting and solidification are characteristic proceses of igneous rock formation.
Molten material that solidifies on the Earth's surface cools rapidly due to exposure to the cooler atmospher or water.
Granite is an example of a felsic, plutonic igneous rock.
Obsidian is an example of a felsic, glassy igneous rock. Glassy rocks form when molten material cools so rapidly that crystals do not have time to form, resulting in a smooth, amorphous texture.
