The Rock Cycle
Different Types of Rocks
Sedimentary Rocks Formation
Metamorphic Rocks Formation
Agents
100
Molten material that forms deep beneath the Earth’s surface
What is magma?
100
Igneous rocks, sedimentary rocks, and metamorphic rocks
What are the three major rock types?
100
Involves the weathering and the removal of rock.
What is erosion?
100
Means to "change form"
What is metamorphism?
100
Provides the energy needed to drive chemical reactions
What is heat?
200
Magma that reaches the surface
What is lava?
200
A type of rock formed 4.5 billion years ago
What are igneous rocks?
200
Occurs when an agent of erosion—water, wind, ice, or gravity—loses energy and drops sediments.
What is deposition?
200
Where most metamorphic changes occur
What is elevated temperatures and pressures?
200
Causes a more compact rock with greater density
What is pressure?
300
Shows the interrelationships among the three rock types; igneous, sedimentary, and metamorphic
What is the rock cycle?
300
Rocks that are changed by heat, pressure or fluids become
What are metamorphic rocks?
300
A process that squeezes or compacts, sediments.
What is compaction?
300
Occurs when magma moves into rock
What is contact metamorphism?
300
Hot water-based solutions escaping from the mass of magma that promote recrystallization by dissolving original minerals and then depositing new ones
What are hydrothermal solution?
400
Any solid mass of material or mineral-like matter occurring naturally as part of our planet.
What are rocks?
400
Formed by the crystallization of molten magma
What are igneous rocks?
400
Takes place when dissolved minerals are deposited in the tiny spaces among the sediments.
What is cementation?
400
Results in large-scale deformation (folding) and high-grade metamorphism
What is regional metamorphism?
400
Metamorphic rocks have a banded or layered appearance
What is foliated?
500
Weathered pieces of Earth elements.
What is sediment?
500
Rocks weathered forming sediment that is compacted and cemented
What are sedimentary rocks?
500
Formed from the weathered products of pre-existing rocks that have been transported, deposited, compacted, and cemented.
What is sedimentary rock?
500
Occurs near a body of magma and is driven by a rise in temperature
What is contact metamorphism?
500
Metamorphic rocks do not have a banded appearance
What is non-foliated?
