100
A rock that is formed when magma or lava cools down
What is igneous?
100
The thinnest layer
What is the crust
100
Heats the magma in the mantle.
What is inner core?
100
Two continental plates colliding can produce.
What is a mountain range?
100
The cracks in Earth's crust along which earthquakes may happen
What is a fault?
200
Created by extreme heat and pressure
What is metamorphic rock?
200
The most dense layer
What is the mantle
200
Heated magma particles become this.
What is less dense?
200
This can occur at a fault like the San Andreas in California
What is an earthquake?
300
The building blocks of rocks.
What is a mineral?
300
The layer that is solid metal
What is inner core
300
Cooled down magma particles become this
What is more dense?
300
The scientist who explained continental drift.
Who is Wegener?
300
Form near a weak spot in Earth's crust where comes up to the surface
What is volcanoes
400
Formed mainly by compaction and cementation.
What is sedimentary rock?
400
The layer that is molten metal
What is the outer core?
400
Besides density, this causes particles to drop towards the core
What is gravity?
400
New ocean floor is added at what type of boundary
What is divergent boundary?
400
Waves of energy generted by an earthquake that travel through earth.
What are seismic waves?
500
Cooled down lava
What is igneous rock?
500
The crust, the mantle, the outer core, the inner core
What is order of the Earth's layers from the outside going in?
500
This is caused by the movement of the convection currents in the mantle.
What is plate movement?
500
The type of fault that occurs at transform boundaries
What is strike-slip?
500
A string of islands that forms where two convergent plate boundaries collide
What is an island arc?
