Igneous rocks formed when lava cools on the Earth's surface.
What are extrusive rocks?
100
Rocks formed from cooled and hardened magma or lava.
What are igneous rocks?
100
Particles of minerals, rock fragments, shells, leaves, bones, and other remains of once-living things.
What are sediments?
100
The process of change in the structure and constitution of existing rocks change due to heat, pressure, and/or chemical reactions.
What are metamorphic rocks?
100
Metamorphism that occurs when large pieces of the Earth's crust rub against each other, causing heat and pressure than change existing rocks.
What is regional metamorphism?
200
Magma that has reached the Earth's surface.
What is lava?
200
The example of a fine-grained mineral.
What is basalt?
200
Clastic rock composed of clay-sized particles in flat layers.
What is shale?
200
The process of change in the structure and constitution of a rock.
What is metamorphism?
200
The process by which one rock type changes into another.
What is the rock cycle?
300
Melted rock beneath the Earth's surface.
What is magma?
300
Rocks formed from sediments that have been compacted and cemented together.
What are sedimentary rocks?
300
A clastic rock composed of rounded, pebble-sized rock fragments.
What is a conglomerate rock?
300
A rock structure without visible layers or bands.
What is nonfoliated structure?
300
The study of rocks and their origins.
What is petrology?
400
A hard substance composed of one or more minerals.
What is a rock?
400
A clastic rock composed of rounded, sand-sized grains.
What is sandstone?
400
Sedimentary rocks made of rock particles and fragments deposited by water, wind, or ice.
What are clastic rocks?
400
Metamorphism that occurs when the heat of magma invades existing rocks.
What is contact metamorphism?
400
The squeezing of air and water out of sediments and the pressing of the fragments together.
What is compaction?
500
Light-colored, lightweight igneous rocks that are rich in silicon, aluminum, sodium, and potassium.
What are felsic rocks?
500
A type of conglomerate rock composed of sharp-cornered fragments.
What is Breccia?
500
The process that transforms layers of rocky fragments into sedimentary rock or a bed of sand into sandstone.
What is lithification?
500
A rock structure with visible layers or bands aligned in planes.
What is foliated structure?
500
Rocks that are formed when salt water is deposited in shallow areas where it can evaporate and rocks can form from cementation?
What are chemical sedimentary rocks?
