GEOLOGY

Detailed explanation-1: -Volcanoes are created by the movement of the Earth’$ plates. Canyons are not created by the movement of the Earth’$ plates.

Detailed explanation-2: -Volcanic activity caused by hotspots is not the result of plate tectonics.

Detailed explanation-3: -Convection currents drive the movement of Earth’s rigid tectonic plates in the planet’s fluid molten mantle. In places where convection currents rise up towards the crust’s surface, tectonic plates move away from each other in a process known as seafloor spreading (Fig. 7.21).
