Rock Cycle
This type of rock is made up of multiple layers pressed together
Sedimentary Rock
This process breaks down rocks into smaller pieces via wind, water and other natural forces
Weathering
Molten rock above ground
Lava
Two main ingredients required to make metamorphic rocks.
Heat and Pressure
Name a sedimentary rock
Sandstone, Limestone, Conglomerate, Chalk, Flint, etc.
This type of rock is made from lava or magma that has cooled over time.
Igneous Rock
This process moves sediments from one location to another.
Erosion
Molten rock below ground
Magma
Name for the wavy lines that sometimes appear on certain types of metamorphic rocks
Foliation
Name an igneous rock
Obsidian, Granite, Felsite, Basalt, Pumice, etc.
This rock is made from heat and pressure deep beneath the earth's surface.
Metamorphic Rock
These horizontal layers are a key feature that can identify a sedimentary rock.
Strata
What is the major source of most igneous rocks found on the surface of our planet?
Volcanoes
True or False: Foliated layers may contain crystals
True
Name a metamorphic rock
Gneiss, Marble, Slate, Schist, Quartzite, etc.
True or False: All rocks will eventually turn into one of every category over millions of years.
True
This process involves buried sediments being squeezed together due to the pressure of overlying layers to create a new rock.
Compaction
These types of igneous rocks are made from lava that quickly cooled on Earth's surface.
Extrusive
True or False: Metamorphic rocks melt and then solidify when being made.
False
Which type of rock never has crystals inside of it?
Sedimentary Rock
True or False: Metals are part of the rock cycle.
False
This process glues sediments together via minerals present in water.
Cementation
These types of igneous rocks are made by magma that slowly cooled underground.
Intrusive
What is the name for metamorphic rocks that do not contain wavy layers?
Non-foliated
Which type of rock never has lines or layers visible on its surface?
Igneous Rock
