Explain the role that internal and external processes play in the formation of the Earth’s relief. Illustrate your explanation with the formation of large mountain ranges and land plains.

Internal forces of the Earth create irregularities of the earth’s surface – mountains, plains, lowlands, etc., and external forces (wind, water, sun, plants, etc.). – align. Internal forces began to act earlier, because first, irregularities should appear on the surface, and then their modification occurs. Internal and external processes are two opposite relief-forming forces.
