Bell Ringer quiz:
What is a mineral?
What is a rock?
What powers the Earth’s rock cycle?
How do fine grained igneous rocks form?
Igneous rock is formed by the crystallization of molten magma.
Sedimentary rock is formed from the weathered products of rocks that have been transported, deposited, compacted, and cemented.
Metamorphicrock is formed by the alteration of pre-existing rock deep within Earth (but still in the solid state) by heat, pressure, and/or chemically active fluids.
Interactions among Earth’s water, air, and land can cause rocks to change from one type to another. This continuous process is called the rock cycle.
Shows the interrelationships among the three rock types
Sediment is weathered pieces of Earth elements.
Eventually sediments are compacted and cemented to form sedimentary rocks.
If the sedimentary rocks get buried deep under the Earth it would be subjected to extreme temperature and pressure. It will then change into metamorphic rocks.
Processes driven by heat from the Earth’s interior are responsible for forming both igneous rock and metamorphic rock.
Weathering and the movement of weathered materials are external processes powered by energy from the sun.
External processes produce sedimentary rocks.
