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.
Lesson Plans: Abiotic Environment. Abiotic Environment Lesson Plans. Water, rocks, wind, sun, temperature and humidity are all examples of nonliving components in ecosystems that can interact with each other and also affect living organisms. How do human activities influence the abiotic environment in urban ecosystems? For example, urbanization has led to decreased agricultural development and increased water control via dams, reservoirs, and canals. The following activities will help you and your students explore abiotic factors that shape your environment.
