plants help because they help to keep the soil up which in turn will keep rivers smaller and keep rocks from falling in or getting worn down as quickly.
Plants weather rocks through root growth, where roots penetrate cracks in the rock causing physical weathering. Animals can weather rocks through activities like burrowing and digging, which can break apart rocks over time through mechanical weathering. Additionally, animal waste can contribute to chemical weathering by altering the composition of the rock.
Plants with their roots can contribute to physical weathering by breaking through rocks as they grow. Burrowing animals such as earthworms and rodents can also contribute by tunneling through the ground and breaking up rock particles. Ice wedging, where water freezes and expands in cracks in rocks, is another process of physical weathering caused by living organisms.
The type of weathering that includes the effects of animals and plants on the landscape is called biological weathering. This process occurs when living organisms contribute to the breakdown of rocks and minerals through physical actions, such as root expansion or burrowing, as well as through chemical processes, like the release of organic acids. Plants can penetrate rock crevices and, over time, contribute to their disintegration, while animals can disturb soil and rock, facilitating further weathering. Together, these biological activities play a significant role in shaping the Earth's surface.
Living things can cause weathering through biological weathering, where plants and animals contribute to the breakdown of rocks and minerals. For example, tree roots can expand and exert pressure on rocks, causing them to crack. Burrowing animals can also contribute to weathering by breaking up rock surfaces.
Yes, plants growing in cracks of rocks can contribute to weathering. As the roots of the plants grow, they can exert pressure on the surrounding rock, causing it to crack and break apart. Additionally, the growth of plants can lead to the accumulation of organic material that can accelerate chemical weathering processes on the rock surface.
There are two primary effects: chemical weathering by acidic secretions, decomposition by-products etc; and wedging of fractured rockby tree-roots. Animals may also create minor, purely local soil erosion, though the so-called "sheep tracks" (miniature terraces)on steep hillsides are formed by soil-creep, not trampling.
Any animal can contribute to rock weathering, simply by stepping on it, brushing up against it, clearing protective plant life away from it, etc. Of course, what type of rock it is would determine how much of an effect animals would have on it.
The sources of weathering include physical factors like wind, water, and temperature changes, as well as chemical factors such as acids, oxygen, and organic compounds. Biological factors like plants, animals, and microbes can also contribute to weathering processes.
Organic weathering is the breakdown of rock and minerals through biological processes such as the action of plants, animals, and microorganisms. This type of weathering can occur through processes like root growth, burrowing, and the release of acids by organisms, leading to the decomposition of rocks over time.
1. The roots of plants sometimes loosen rock material. A plant growing in a crack in a rock can make the crack larger as the plant's roots grow and spread out. This is called root-pry. Root-pry is an organic activity or an activity caused by living things.
Animals dig holes the dirt goes other places and that causes erosion. When coyotes howl, it can cause erosion by making rocks tumble Animals dig holes the dirt goes other places and that causes erosion.

They expand within cracks in rock to break the rock apart
