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.
There's numerous biotic and abiotic factors of an ecosystem. Some include: abiotic: cool summers, windy conditions, heavy precipitation, fast flowing rivers, fast changes in a â¦ ltitude, and the temperatures vary with elevation. biotic: wildlife animals in the mountain forest like grizzly bears, cougars, etc.biotic factors are non-living parts of the environment that affect living organisms. The broad range of abiotic factors can be divided into two main categories: the physica â¦ l environment (terrain type, amount of water present, soil fertility) and weather (wind, cloud cover, temperature).
