Answer :

If tectonic plates were to stop moving, several consequences could occur:

1. There will be no new mountain formations: The movement of tectonic plates is responsible for the creation of mountains through processes like subduction and collision. If the plates stop moving, the formation of new mountains would cease.

2. Volcanic activity may increase: When tectonic plates move, they interact with each other, leading to volcanic eruptions. If the plates stop moving, the pressure and interactions that cause volcanic activity may intensify in certain areas.

3. Continents will not move towards the poles: The movement of tectonic plates plays a role in the shifting of continents over geological time scales. If the plates were to stop moving, this gradual movement of continents towards the poles would be affected.

In summary, if tectonic plates stopped moving, it would impact the formation of mountains, potentially increase volcanic activity, and alter the gradual movement of continents.
