Why are tectonic plates moving?
A
They aren't moving.
B
The plates are carried along by convection currents in the mantle.
C
The plates move because the inner core rotates.

Which description matches the asthenosphere?
* The rocky outer topmost layer of the Earth
* The plastic top layer of the Earth's mantle
* The liquid inner layer of the Earth
The plastic top layer of the Earth's mantle
300
What causes the movement of tectonic plates?
* Convection currents on the crust push and pull on the plates of the crust
* Convection currents in the mantle push and pull on the plates of the crust
* Convection currents in the core push and pull on the plates of the crust
Convection currents in the mantle push and pull on the plates of the crust
300
How is an ocean basin formed?
* Two convergent continental plate boundaries collide
* Two plate boundaries diverge
* Two plate slide past each other
Two plate boundaries diverge
300
What processes occur at arrow 4?
* Melting and cooling
* Weathering and erosion
* Heat and pressure
Weathering and erosion
300
How can magma turn into Igneous Rock?
Crystallization
400
True or false:
The inner core is less dense and thinner than the mantle
False
400
What can be used to model tectonic plates?
* A cake with layers
* A jigsaw puzzle
* A rock
A jigsaw puzzle
400
How do volcanoes form?
* Divergent boundaries form mountains and subduction allows magma to come up to the surface
* Convergent boundaries form mountains and subduction allows magma to come up to the surface
* Transform boundaries form mountains and subduction allows magma to come up to the surface
Convergent boundaries form mountains and subduction allows magma to come up to the surface
400
How does erosion transform an island into a seamount?
Energy from the sun causes the movement of wind and water, which transports sediments from the island the ocean.
400
What processes occur at 6 to turn sedimentary rock into igneous rock?
* Sedimentary rock is pushed underground where it melts and then cools to become igneous rock
* Sedimentary rock undergoes intense heat and pressure to become igneous rock
* Sedimentary rock is compacted and cemented into igneous rock
Sedimentary rock is pushed underground where it melts and then cools to become igneous rock
500
Which layer of the Earth is considered molten, where convection occurs?
* The outer core
* The inner core
* The mantle
The mantle
500
What is the name of the rocky portion of Earth's layers that is made up of the uppermost mantle and the crust?
Lithosphere
500
If one tectonic plate is moving Southeast while another is moving Northwest, what type of boundary is present between them?
Divergent
500
What part of the rock cycle is involved in mountain formation?
* Igneous rocks form from the heat and pressure under mountains which is then pushed up to the surface.
* Metamorphic rock forms from the heat and pressure under mountains. They are then pushed up to the surface.
* Sedimentary rock forms from the heat and pressure under mountains. They are then pushed up to the surface.
Metamorphic rock forms from the heat and pressure under mountains. They are then pushed up to the surface.
