RES Earth's Plates

What are divergent boundaries?

• Areas where two plates grind past each other

• Areas where plates move away from each other

• Areas where plates move toward each other

What are subduction zones?

• Areas where two plates grind past each other

• Areas where an oceanic plate meets a continental plate and is pushed underneath it

• Areas where plates move toward each other and collide

What is the Theory of Plate Tectonics?

• According to this theory, Earth's outer crust is divided into several plates. These plates consist of the crust and a small amount of the underlying mantle. The Plates move due to convection currents within the mantle.

• A supercontinent that existed long, long ago

• The hypothesis that the continents slowly move across the Earth's surface

What are plates?

• Rigid slabs of rock that make up the Earth's lithosphere

• The hypothesis that the continents slowly move across the Earth's surface

• A break in the Earth's crust along which rocks move

What causes the plates to move?

• The rotation of the Earth around the Sun.

• Gravitational pull from the Moon.

• Convection currents in the mantle.

What is a transform boundary?

• Areas where plates move away from each other.

• Areas where plates move toward each other and collide.

• Areas where two plates slide past each other horizontally.

What is a convergent boundary?

• Areas where plates move away from each other.

• Areas where two plates slide past each other horizontally.

• Areas where plates move toward each other and collide.
