  • What causes earthquakes?

  • I, me and myself.

  • You show off.

  • An earthquake is violent shaking of the earth's crust.

  • The earth's crust is a hard outer covering made up of many pieces called tectonic plates.

  • These plates are always moving.

  • However, the motion is very slow.

  • In a year, they move only 2 to 5 cm.

  • My hair grows faster than their movements.

  • Absolutely.

  • Mostly when these tectonic plates move, they brush against each other without causing great damage.

  • However, sometimes they get stuck and cannot easily slide against each other.

  • But the plates still keep pushing, thus creating pressure.

  • Eventually, the pressure builds up so much that one of the plates suddenly moves above the other.

  • They may crash into each other, causing the crust to shake violently, thus creating an earthquake.
