Question

4) Tectonic plates make up the surface of the earth. These are moved by
*
heat waves
earthquakes
convection currents
hot lava

Answer 1

The correct answer is convection currents. Tectonic plates are large pieces of the Earth's lithosphere that fit together like a jigsaw puzzle. The movement of these plates is caused by convection currents in the underlying asthenosphere, which is a layer of semi-fluid rock in the Earth's mantle. As hot material rises and cooler material sinks in the asthenosphere, it creates a circular motion called convection, which is responsible for moving the tectonic plates. Earthquakes and volcanic activity can occur as a result of the interaction and movement of these plates.
