Answer:
First of all, tectonic plates are always moving, even if we may not feel them. This movement causes many things to happen, and change the earth. ... When two plates are moving, and they hit each other, one will slowly be pushed down beneath the other, and create a volcano
Step-by-step explanation:
The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel.
