Year 8 Tectonics Unit Vocab Quiz

What is a tectonic plate?

• The giant slabs/sections of the Earth's crust.

• Where two tectonic plates meet.

• An area of the Earth's mantle.

What is a plate boundary?

• The giant slabs/sections of the Earth's crust.

• Where two tectonic plates meet.

• An area of the Earth's mantle.

What is an earthquake?

• Tectonic hazard where friction released causes shaking of the ground.

• Tectonic hazard where magma is released on the Earth’s surface as lava.

• Tectonic hazard where shaking causes a huge wave chain to hit the shore.

What is the focus of an earthquake?

• The centre point of the earthquake where pressure is released and the origin of seismic waves.

• The centre point of an earthquake on the Earth’s surface.

What is the epicentre of an earthquake?

• The centre point of the earthquake where pressure is released and the origin of seismic waves.

• The centre point of an earthquake on the Earth’s surface.

What is a seismic wave?

• The large wave chains caused by an earthquake, a tsunami.

• The shockwaves that roll out of an earthquake, in the Earth's crust.

What is subduction?

• The movement of one tectonic plate against another.

• The downward movement of one tectonic plate beneath anther.

• When an earthquake happens on the ocean floor.

What is a convection current (in tectonic theory)?

• Where hot mantle rises over cooler mantle, in a circular motion.

• Where cooler mantle rises over hot mantle, in a circular motion.

What is a constructive plate boundary?

• Where two plates move away from each other.

• Where two plates move towards each other,

• Where two plates slide past each other.

What is a conservative plate boundary?

• Where two plates move away from each other.

• Where two plates move towards each other,

• Where two plates slide past each other.
