Why is it that not all movements along faults produce earthquakes?

• It is because the energy of the Earth that causes the rocks to move is very strong enough.

• It is because the friction between rocks was not overcome by the energy of the Earth.

• It is because there is no friction present between the rocks.

• It is because the layers of rocks were not broken.

This is the area beneath the Earth's surface where the earthquake begins

• epicenter

• focus

• fault line

• tectonic plate

Answer explanation

The area beneath the Earth's surface where an earthquake begins is referred to as the 'focus'. This is not the 'epicenter', which is the point on the surface above the focus. It's also not the 'fault line' or the 'tectonic plate', which are larger geological structures. So, the correct answer to the question is 'focus'.

How do faults produce earthquakes?

• Energy from inside the Earth makes the ground move, once friction is overcome, a fault slips producing an earthquake.

• Rock materials from underneath go out along faults produces earthquakes

• Magma spreads beneath the rock layers producing faults.

• Tectonic plates collide producing earthquakes.
