The movement of the Earth’s plates causes earthquakes.
Explanation: When tectonic plates collide, slide past each other, or move apart, they can generate friction and pressure, leading to earthquakes.
Why other options are incorrect:
Cyclones:
These are weather phenomena formed by rotating winds over water. They are caused by atmospheric conditions, not plate tectonics.
Lightning:
Lightning is a natural electrical discharge that occurs during thunderstorms. It’s a result of atmospheric interactions, not plate movements.
Thunderstorms:
These are severe weather events characterized by strong winds, rain, lightning, and thunder. While related to weather patterns, they are not caused by plate tectonics.
