Rock Falls- For over 153 years, rock falls have been happening at Yosemite National Park. These rock falls are considered an abiotic factor because the large rocks that fall from cliffs can land on animals and either injure them badly or even kill them.

Snow Melt- since there is snow in Yosemite, plants do not get that much water and sun. If the snow did not melt the plants would die from not recieving enough sun or water.

Essential Question: How would global warming affect Yosemite National Park?

Global warming would mostly affect the animals in Yosemite National Park. The lives of animals like bears, beavers, and wolverines would be at risk because they all have a lot of fur. This would create a problem beacause these animals would most likely die from being overheated. Also, Yosemite is located in California and it is already very warm there. Global warming would just make it hotter, not only for the animals that live there, but for the millions of people who visit Yosemite every year. In addition, global warming would raise the temperatures and evaporate most of the water from many of Yosemite's beautiful freshwater lakes, rivers, and creeks. This would decrease the amount of space for fish and algae to live.
