What is the outer shell of the Earth called?
Hint: It extends to a depth of 100 km
Lithosphere
100
What's the partially melted layer of the mantle called?
Hint: It lays beneath the Lithosphere
Asthenosphere
100
In the collision zone, what happens?
Continental plates collide, crush together, and form mountains and cause earthquakes.
100
What is a Metamorphic rock?
A type of rock formed by great amounts of heat and pressure.
100
True or False:
The rock cycle goes in a specific order like photosynthesis.
False
200
What is the theory of plate tectonics?
Theory of the formation and movement of the plates that cover the Earth's surface.
200
What is the Lithospheric Plate?
The number of rigid, but moving pieces of the Earth's surface.
200
What happens around the magma chamber when the oceanic crust melts into the mantle?
Earthquakes occur and volcanoes are formed on the continental plate
200
What is a Igneous rock?
A type of rock formed by cooled magma
200
What are the three types of Sedimentary rocks?
Organic, Clastic, & Chemical
300
What does the seafloor spreading state?
States that the youngest rocks of the ocean floor are moving outward.
300
True or False:
The continental drift is the theory that all continents are fragments of Pangaea, but are slowly drifting apart.
True
300
What is the subduction zone?
Subduction zone is where the edges of the heavier oceanic plate slowly sink below the continental plate.
300
What is a sedimentary rock?
A type of rock formed by broken down pieces of rock, decayed plants/animals, & fossils layered on top of each other.
300
What is the difference between intrusive and extrusive igneous rocks?
Intrusive igneous rocks form inside the volcano, while extrusive igneous rocks form outside of the volcano.
400
What are diverging boundaries?
Forms when two lithospheric plates move apart
400
What are sliding boundaries?
Forms when two lithospheric plates slide past each other.
400
What is the Mid-Ocean Ridge/Spreading Center?
Formed by the plate edges ripping the plate in the middle and the magma that rises cool off new layers of crust onto it.
400
What is erosion?
Erosion is the process of breaking down something by wind, water, or other natural agents.
400
Name three natural resources that help break down igneous and metamorphic rocks.
Wind, water, & ice
500
What are converging boundaries?
Forms when two lithospheric plates come together.
500
What are faults?
A fracture in the continuity of a rock formation caused by a shifting or dislodging of the earth's crust
500
True or False:
The subduction zone helps create the Mid-Ocean Ridge/Spreading Center
True, because when the plate's edges sink, it tears the center of the plate apart.
500
What is the rock cycle?
The rock cycle is a cycle of processes undergone by rocks in the earth's crust, involving igneous intrusion, erosion, transportation, deposition as sedimentary rock, metamorphism, remelting, and further igneous intrusion.
500
True or False:
The rock cycle can only form different rocks with heat and pressure only.
False, wind, water, erosion, ice, fossils, dead plants, dead animals, etc.
