A mixture of molten minerals, organic matter, volcanic glass, or other materials.
What is a rock?
100
Molten rock or liquid either above or underground.
What is magma and lava?
100
Conglomerate and breccia are examples of this type of sedimentary rock.
What is a clastic sedimentary rock?
100
How rocks can bend or fold without melting.
What is Plastic Deformation?
100
Molten liquid or rock underground.
What is magma?
200
The three main types of rocks.
What are igneous, sedimentary, and metamorphic rocks?
200
An igneous rock formed from lava above ground.
What is an extrusive igneous rock?
200
The broken pieces found in sedimentary rocks.
What are clasts?
200
The two things that effect igneous or sedimentary rocks to change them into metamorphic rocks.
What is heat and pressure?
200
Weight from layers of sediment pushes out liquid and decreases grain space.
What is Compaction?
300
A way rocks can be changed into sediment.
What is weathering and erosion?
300
An extrusive igneous rock.
What is basalt?
300
The three main types of sedimentary rocks.
What are clastic, chemical, and biochemical?
300
A metamorphic rock with distinct parallel layers.
What is a foliated rock?
300
Limestone with remains of organisms in them.
What is Fossiliferous limestone?
400
The fragments that make up rocks.
What are grains?
400
Intrusive igneous rocks.
What is a igneous rock formed underground by hardened magma?
400
The process in which clastic rocks are created.
What is Erosion, transportation, deposition, and cementation?
400
When mountains are created that cover a large area.
What is regional metamorphism?
400
A tectonic process that forces rocks up from beneath Earth's surface.
What is uplift?
500
Heat and pressure form this type of rock.
What is a metamorphic rock?
500
A rock that cools too quickly to form crystals.
What is Volcanic glass?
500
The process in which pressure from the upper layers of sediment pushes down on the lower layers, causing the sediment to stick together to form solid rock.
What is cementation?
500
When magma touches its surrounding rock and its thermal energy changes that rock.
