Energy from inside the Earth makes the ground move. Which of the following is the reason why there is no movement right away?

• Friction causes the delay on the movement of the ground.

• There is no movement right away because of the bending of the rocks.

• There is no movement right away because of the vibration of the rocks.

• The rapid release of energy causes the delay of the movement of the ground.
