Factors Affecting Global Climate. Citation: Stevens, A. N.P. (2011) Factors Affecting Global Climate. Earth is a dynamic planet, constantly undergoing change driven by internal and external forces.

These valleys may eventually become lakes, seas, and oceans. On the surface, the greatest factor affecting Earth is sunlight.
