The right answer is D. earthquake
The term geosphere is globally synonymous with "planet Earth" or "terrestrial globe".
An earthquake, or earthquake, is translated on the surface by vibrations of the ground. It comes from the fracturing of the rocks in depth. This fracturing is due to a large accumulation of energy that is released, creating or replaying faults, when the threshold of mechanical rupture of the rocks is reached.
The Earth's crust (the geosphere) consists of several large plates that evolve relative to each other: some deviate, others converge, and others slide. About 90% of earthquakes are located near the boundaries of these plates.
