How do you explain the features of an earthquake?

Answer 1

Earthquakes cause their damage with shockwaves. You have the focus, the point where the earthquake started and the epicentrre, the point above ground where the waves spread out from. These waves can often give the appearance of the ground moving up and down, when travelling up a motorway fro example. Also these waves are similar to the shockwave of a large explosion.

Answer 2

Earthquakes are a shaking of the ground. They happen when the rocks that make up the earth's crust become squashed, a bit like squashing a spring. If you keep trying to squash a spring (or the opposite, stretch an elastic band) it will eventually break. The same is true for the rocks that make up the crust under our feet. When the squeezing or squashing becomes too much for the rocks, they will break, and the rocks suddenly jerk back into place (a bit like a snapped elastic band). This causes the shaking that is felt by people and called an earthquake.

Answer 3

An Earthquake is a sudden movement of the earth's crust caused by the release of stress accumulated along geologic faults or by volcanic activity. ( Online dictionary).

Answer 4

0 cannot describe an earthquake because if it is 0 it is not an earthquake. but more than 0 is an earthquake
