any solid mass of mineral or mineral-like matter occurring naturally as part of our planet.
What is rocks
100
Formed by the crystallization of molten magma (lava).
What is igneous rock?
100
Their composition and texture.
What are igneous rocks clasified by?
100
The weathered products of pre-existing rocks that have been transported,
What is sedimentary rock formed by?
100
The energy needed to drive chemical reactions.
What does heat provide?
200
Igneous rocks, sedimentary rocks, and metamorphic rocks.
What are the 3 types of rocks?
200
Formed from the weathered products of preexisting rocks that have been transported, deposited, compacted, and cemented.
What is sedimentary rock?
200
Caused by slow cooling resulting in larger crystals.
What is coarse-grained texture?
200
Rock being broken apart by weather – freezing/thawing, water, or wind.
What does weathering involve?
200
Causes a more compact rock with greater density.
What is pressure?
300
molten material that forms deep beneath the Earth’s surface.
What is magma
300
Formed by the alteration (means changing) of pre-existing rock deep within the Earth (but still in the solid state) by heat, pressure, and/or chemically active fluids.
What is metamorphic rock?
300
Caused by very rapid cooling.
What is glassy texture?
300
The weathering and the removal of rock.
What is erosion?
300
Hot water-based solutions escaping from the mass of magma
What is hydrothermal solutions?
400
A process in which rocks are broken down by water, air, and living things
What is weathering?
400
Weathering and the movement of weathered materials (sediment) are external processes powered by energy from the sun.
What external processes produce sedimentary rock?
400
Made mostly of light-colored quartz and feldspar.
What are granintic composition rocks?
400
A process that squeezes, or compacts, sediments.
What is compaction?
400
Recrystallization
What do hydrothermalsolutions promote?
500
Weathered pieces of Earth elements.
What is sediments
500
Processes driven by heat from the Earth’s interior
What is responsible for forming both igneous rock and metamorphic rock
500
Between granitic light-color minerals and basaltic composition dark-colored minerals.
What are andesitic composition rocks?
500
Takes place when dissolved minerals are deposited in the tiny spaces among the sediments.
What is cementation?
500
By dissolving original minerals and then depositing new ones.
How do hydrothermal solutions promote recrystillization?
