AQA GCSE Geography revision on Tectonic hazards — earthquakes & volcanoes. Aligned to the AQA GCSE Geography 8035 specification. This bank has 10 practice questions on this topic.
Sample questions (3 of 10)
-
Question 1
What is the name of the point inside the Earth where an earthquake originates?
Show answer
Answer: Focus
The focus, also known as the hypocenter, is the point of rupture where seismic energy is first released. Directly above this point on the Earth's surface is the epicentre.

Question 2
Which of the following describes the movement at a conservative plate margin?
- A) Plates move towards each other
- B) Plates slide past each other
- C) Plates move away from each other
- D) Plates subduct under each other
Show answer
Answer: Plates slide past each other
At conservative plate boundaries, friction causes plates to become stuck. When the pressure is eventually released, it causes a sudden earthquake, though no volcanic activity occurs here.

Question 3
What is the instrument used to measure the magnitude of an earthquake?
Show answer
Answer: Seismometer
A seismometer detects the vibrations caused by seismic waves and produces a seismograph. This data is then used to calculate the earthquake's magnitude on the Moment Magnitude Scale.
