What is the theory of continental drift? Who proposed it?

What is theory that the continental landmasses were “drifting” across the Earth, sometimes plowing through oceans and into each other. Alfred Wegener called this movement continental drift.

Magma heats up when it is closest to the....
outer core.
100
This is the layer of the Earth we live on.
What is the crust?
100
The crust is made up of pieces called THIS.
What is tectonic plates?

What is a convergent plate boundary?

What is a place where two tectonic plates move towards each other, eventually colliding. 

200
What are the three disasters caused by tectonic activity?
volcanoes, tsunamis, earthquakes

Magma cools down when it is close to the...
crust.
200
This is the layer of the Earth that does not move.
What is the inner core?
200
The Himalayas are caused by this.
What is the Indian plate subducting under the Asia plate.

What is a Transform Boundary?

What is when two plates slide past one another.

300

Where do faults occur?

Middle of plates/Divergent boundaries 

300
When a liquid heats up, what happens to its volume?
Expands, gets bigger
300
This is where convection currents occur.
What is the mantle?
300
Volcanoes happen when two plates BLANK.
What is come together, subduct?
300

What is a Divergent Boundary?

What is when two tectonic plates move apart.

400

How are mountain ranges created?

What is when two plates converge.

400
When a liquid heats up, what happens to its density?
Becomes less dense

Where is the lithosphere located?

What is the crust and upper mantle

What is the Inner Core and the Crust?
500
This is where two plates are separating.
