What causes the movement of Tectonic Plates?
Convection currents in the Mantle
100

What is the outermost layer of the Earth's surface called?

the crust

100

There are 3 pieces of evidences that support Wegener's Theory of continental drift. Name one.

Fossil record, continent shapes, and rock layers

100

Hawaii formed on top of a ________.

Hotspot

100

When this material reaches the surface of the Earth it is called this.

Lava

200

What natural disaster occurs because of plate movement?

volcanoes or earthquakes

200
What is a boundary where two plates slide along each other?
Transform
200

What geographical feature is caused under water at a divergent boundary in the Atlantic Ocean?

Mid-Atlantic Ridge

200

What plate boundary produces sea-floor spreading?

Divergent

200

When rocks get too hot what do they become and what type of rock will they form when cooled?

Magma, they will form igneous rock

300

Where do convection currents occur?

Mantle

300
What do you call the area where two tectonic plates meet?
Plate Boundary
300

What happens when a continental plate converges with a continental plate?

Mountain building/ uplift

300
What type of boundary is made when two tectonic plates collide?
Convergent
300

What are the two types of igneous rock and how are they different?

Extrusive - formed on the Earth's surface

Intrusive - formed in the Earth's crust

400

Super Continent that scientists believe existed and evidence of continental drift.

Pangaea

400

If an oceanic and continental crust converge, what will happen and why?

the oceanic crust will slide under the continental crust because it is more dense (making trenches, volcanoes, mountain ranges)

400
What hardens to form new rock at mid-ocean ridges?
Magma
400

Movement of matter caused by differences in density and temperature. 

Convection

400

When rock gets weathered this is formed:

Sediment

500
Who developed the theory of continental drift?
Alfred Wegner
500

What layer of earth do tectonic plates sit on? This layer is below the lithosphere

Asthenosphere

500
What is the theory that the earth's surface is broken up into large pieces that float on top of the asthenosphere?
The Plate Tectonic Theory

The type of tectonic plate boundary that sometimes has a subduction zone is ______.
Convergent Boundary
500

The type of rock formed due to immerse temperature and pressure in the Earth's crust

Metamorphic
