Question

Why is the surface of the earth uneven?

Answer 1

• Endogenic Forces (Internal Forces): Forces originating from within the earth (such as tectonic movements, folding, faulting, and volcanism) continuously uplift, depress, and build up parts of the earth’s crust, creating major relief features like mountains, plateaus, and valleys.
• Exogenic Forces (External Forces): Forces acting on the earth’s surface (driven by solar energy and gravity, such as running water, wind, and glaciers) continuously wear down high relief features through erosion (degradation) and fill up depressions through deposition (agradation).

The continuous, simultaneous action of these internal building forces and external wearing-down forces keeps the earth’s surface dynamic and uneven.
