What is the name of the third (3th) layer of the Earth? (start counting on the outside)

1. Inner core
2. Outer core
3. Mantle
4. Crust

In which layer do we find convection currents (moving magma)?

1. Inner core
2. Outer core
3. Mantle
4. Crust

Crust

Mantle

Outer core

Inner core

A layer of liquid metal

A layer of solid rock

A layer of solid (hard) metal

A layer of molten/ syrupy rock

Put the steps of convection currents in the right order:
1-To lose its heat, the magma moves toward the surface of the earth.
2-The magma cools down here.
3-It is very hot in the mantle.
4-The cooled rock then sinks back into the mantle.
5-The earth wants to lose heat.

1. 1, 2, 3, 4, 5
2. 3, 5, 1, 4, 2
3. 3, 5, 1, 2, 4
4. 3, 1, 5, 2, 4

What is the reason that there are Earthquakes? (answer in a few words)

We use this to measure how strong an earthquake is

1. Scale of Richter
2. Scale of Epicentre
3. Ring of Fire
4. Scale of Beaufort

The hypocentre is

1. The place on the Earth where you can feel the earthquake best.
2. The place deep in the Earth where the earthquake starts.
3. This is how you call a piece of the Earth’s crust.
4. A shelter where you can go after an earthquake.

The Earthquakes in Groningen are special. Why is that? (answer in short sentence)
