What causes earthquakes and volcanic eruptions, and creates mountains and ocean basins? a. the water cycle and the moon's gravitational influence b. the tides and solar eclipses c. the carbon cycle and the earth's magnetic field d. heat flow and the movement of material inside the earth

Heat flow and the movement of material inside the earth cause earthquakes and volcanic eruptions and create mountains and ocean basins.

Option D

Explanation:

The inner core of the earth consist of very hot material because of the high temperature of the centre of the earth. The interior of the earth also consists of tectonic plates that move in a continuous manner causing the hot material inside the earth to also move. This hot material moving at a high speed results in volcanoes and earthquakes.
