Climate is an abiotic factor - think about how many individual abiotic factors make up something as large as a climate. Natural disasters, such as earthquakes, volcanoes, and forest fires, are also abiotic factors. These types of abiotic factors certainly have drastic effects on the ecosystems they encounter.
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. Currents of magma within our planet move the plates that form the continental crust in a constant process that builds mountains and creates valleys. These valleys may eventually become lakes, seas, and oceans. On the surface, the greatest factor affecting Earth is sunlight.
