Known around the world for its towering granite cliffs, serene mountainside waterfalls, giant sequoia groves, sprawling meadows, and biological diversity, Yosemite in California’s Sierra Nevada. Repeating this process allows small pieces of rock to fall off. With the presence of land plant, weathering intensity. The organic processes involve biological dissolution of rocks from bacterial activity, humic acids and bioerosion or. As the roots grow bigger they push open cracks in the rocks making them wider and deeper. Many biologists think of the developmental processes by which organisms progress from egg to adult in terms of the execution of a “developmental program”. Basically, the rocks are still made up of the same types of rocks and contain the same minerals they once did, they are just no longer in the same size or shape as before. These lichens slowly eat away at the surface of the rock and cause it to break down. Biological weathering is a function of biotic energy expenditure. Large waves hit the shore. Biological weathering takes place under the influence of life activities of organisms.
