It is a break in the Earth’s crust
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 vibration of the rocks.
There is no movement right away because of the bending of the rocks.
