What are the different plate boundaries?

This lesson will look at the four different types of plate boundaries and the tectonic activity that occurs at each one.

Intro quiz - Recap from previous lesson

Before we start this lesson, let’s see what you can remember from this topic. Here’s a quick quiz!

Question 1

Question 2

Question 3

Question 4

Question 5

Q1.Convection currents are...

Currents caused by the core cooling the semi-molten rock in the mantle and causing it to rise. Currents in the Earth’s mantle which rise from the Earth’s core and move the tectonic plates. Currents in the Earth's crust that cause the tectonic plates to move.

1/5

Q2.As the rock in the lower mantle heats up and melts it expands which means that...

It becomes less dense (lighter) so it rises. It becomes denser (heavier) so it falls. It stays the same density and so does not rise or fall.

2/5

Q3.Convection currents cause the tectonic plates to move because...

The semi-molten rock is thick and viscous and so sticks to the bottom of the tectonic plate. The semi-molten rock is thin and runny and so sticks to the bottom of the tectonic plate.

3/5

Q4.Ridge push happens...

Between two rising convection cells when the semi-molten rock rises and pushes up between two tectonic plates pushing them apart. Where the semi-molten rock starts to fall back down and the heavy oceanic plate plunges down into the mantle. When the core heats the semi-molten rock in the mantle causing it to rise. When two plates collide into each other and push the land upwards.

4/5

Q5.Slab pull happens...

Between two rising convection cells when the semi-molten rock rises and pushes up between two tectonic plates pushing them apart. Where the semi-molten rock starts to fall back down and the heavy oceanic plate plunges down into the mantle. When two plates pull apart, creating a gap through which semi-molten rock (magma) rises and causes a volcano. When the core heats the semi-molten rock in the mantle causing it to rise.

Quiz:

What are the different types of plate boundary?

Don’t worry if you get a question wrong! Forgetting is an important step in learning. We will recap next lesson.

Question 1

Question 2

Question 3

Question 4

Question 5

Q1.At a constructive plate boundary the tectonic plates move...

Towards each other. Alongside each other. Away from each other.

1/5

Q2.At a collision plate boundary you find...

Only volcanoes. Only volcanoes and earthquakes. Only volcanoes, earthquakes and fold mountains. Only earthquakes and fold mountains.

2/5

Q3.At a conservative plate boundary...

Land is destroyed. No land is created or destroyed. New land is created.

3/5

Q4.The two types of plate boundary where you find both volcanoes and earthquakes are...

Constructive and destructive. Constructive and conservative. Collision and destructive. Constructive and collision.

4/5

Q5.At a destructive plate boundary...

Continental crust and oceanic crust move towards each other and the continental crust subducts (sinks) as it is heavier. Continental crust and oceanic crust move towards each other and the oceanic crust subducts (sinks) as it is heavier. Continental crust and continental crust move towards each other and push upwards creating fold mountains.
