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.

Abiotic factors are the nonliving physical and chemical components of an ecosystem, while biotic factors are the living components of an ecosystem. Both types of factors affect reproduction and survival. Abiotic factors include moisture, sunlight, soil chemistry, temperature, water chemistry and precipitation. These factors have a significant impact on the reproduction and survival of each species in an ecosystem. Without the right amount of sunlight or moisture, for example, some plants are unable to survive.
