Question

What is an earthquake? What are the two main situations in which earthquakes occur?

Answer 1

Answer:

the brainliest

Explanation:

Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little.

Answer 2

Earthquake

Explanation:

An earthquake is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. The focus is the place inside Earth's crust where an earthquake originates. The point on the Earth's surface directly above the focus is the epicenter. When energy is released at the focus, seismic waves travel outward from that point in all directions.

The two main situations in which earthquake occurs are:

1. Volcanic Eruptions.
2. Tectonic Movements.
