Q
What is an earthquake?

Earthquakes are caused by the movement of tectonic plates which are moving slightly due to the movement of magma in the layer below. This causes plates to squeeze together, move apart and slide alongside each other.
2
Q
What are the different types of plate movement?
A
Plate movements: convergent, divergent and transform
3
Q
How are we able to measure the size of an earthquake?
A
The size of an earthquake is referred to as its magnitude on a scale from 1 – 10. Magnitudes as low as 1 are measured in mines due to rock bursts and the maximum magnitude possible is less than 10.
