Summary

Earthquakes happen when the rocky plates that make up the surface of our planet move against each other. But what about quakes in other parts of our galaxy? Do the stars shake? Do planets get their crusts crumbled? We asked astrophysicist Ian Hall to help us find the answer.

Got a question that’s quaking your world? Send it to us at BrainsOn.org/contact, and we’ll serve you an answer on a tectonic plate.
