The earth can shake fast. That is an earthquake.
A rock under the ground cracks and slips. That makes the shake.
The top of the earth is in big parts. They are plates.
Plates push and slide. They go very slow.
Plates can get stuck.
A fault is a crack in rock. One side can slide past.
When it shakes, drop, cover, and hold on.
A strong desk is close? Crawl under it.
Hold on till the shaking stops.
We practice in drills at home and in class.
