Erosion is a continual process, and it can be caused naturally or through artificial means. While many people associate erosion with negative things like land slides and poor soil conditions, it is an important part of the geologic processes which make the Earth what it is. As soil and rock are slowly worn down, they cycle through the Earth's crust and the general environment, causing a constantly shifting and varied surface.

One of the most powerful causes of erosion is water. Water is sometimes called the universal solvent, because it is so effective at dissolving and changing things. Rain and runoff contribute to erosion, as do glaciers, snow, and ice. Ice can be particularly insidious, because it will literally rip rock and soil apart as it expands and contracts. Many seashores distribute spectacular examples of water erosion, in the form of huge terraces of rocks slowly worn away by the ocean.
Tectonic movement can also contribute to erosion, as can the wind. Wind transports materials from one place to another, and in extremely windy locations it can contribute a powerful scouring force to the process of erosion. Materials also naturally tend to slide down a slope, in a process called mass wasting. This downward pull is what causes mountains to slowly melt into hills and plains, and it is constantly happening, although not always in the spectacular form of a landslide.
Humans can also bring about erosion, usually through poor land management. Overgrazing, for example, is a serious cause of erosion. Cows in particular are known for causing serious problems, especially along river banks. Areas which have been heavily grazed for centuries show clear signs of erosion and soil exhaustion due to the demands made on the soil. Deforestation can also cause erosion, since it strips the protective surface plants and trees from the soil. The soil is no longer held in by roots and plant matter, so it slides away in rainy periods.

What human activities may cause or contribute to chemical weathering?
People also weather rocks through many of their activities. To build roads, they sometimes have to blast with dynamite the large rocks along mountainsides. These rocks are broken into fragments. They dig tunnels for mining operations. They dig out large rocks and sand in large open pits called quarries. The rocks and sand that they quarry are used for construction. People build factories to manufacture the things they need. Factories release some chemicals which, when combined with water in the atmosphere, produce acid rain. Acid rain can eat into rocks and break them. Pamela S. =p
Where does dust come from and why does it?
Dust is small ground up particles of all kinds of solids including rocks. It comes from natural erosion and human wear and tear.
Scientists divide rocks into groups based on what?
Rocks are grouped by how they are formed. There are 3 types of rocks. Sedimentary, Metamorphic, and Igneous rock. Sedimentary rocks are made from broken down rocks, called sediment, which come from all three rocks. Metamorphic rocks come from existing rocks that are changed by heat and pressure. The Igneous rocks are formed from magma that rose up to the surface, also known as lava. When the lava cools and hardens it forms igneous rocks. That is a rock cycle.

What word defines vibrations caused by an earthquake?
It is when the rocks are breaking under pressure, elastic rebound, and the forces pushing/pulling on rocks.
What type of rock are mostly found in mountains?
volcanic mountains are mostly associated with igneous rocks and sedimentary rocks at their slopes can be found due to weathering,but mountains such as fold mountains can contain igneous rocks,metarmophic ro cks and even sedimentary rocks at their slopes
How do humans contribute to mechanical weathering?
Humans contribute to mechanical weathering by activities such as construction, mining, and agriculture. These activities can expose rocks to physical forces like pounding, vibrations, and drilling, accelerating the process of breaking down the rocks into smaller fragments.
What man activities that can help breaking the rocks?
by mining
How do waves breaks down the rocks?
it what ways do people contribute to the breaking down of rocks
How do humans contribute to weathering of rocks on earth?
Humans contribute to weathering of rocks on Earth through activities such as mining, construction, agriculture, and deforestation. These activities can lead to physical weathering through the disturbance of rocks and soil, as well as chemical weathering through the release of pollutants that react with and deteriorate rocks. Overall, human activities can accelerate the natural processes of weathering and erosion.
How do people contribute to weathering of rocks?
People can contribute to the weathering of rocks by activities such as construction, mining, farming, and deforestation, which can expose rocks to the elements and accelerate their breakdown. Pollution, such as acid rain from industrial emissions, can also contribute to the chemical weathering of rocks. Additionally, human activities like the use of heavy equipment and vehicles can lead to mechanical weathering through processes like abrasion and impact.
How does people and human contribute to weathering of rocks?
People contribute to weathering of rocks through activities such as mining, construction, and pollution, which can accelerate the breakdown of rocks. Humans also indirectly impact weathering by altering landscapes through deforestation and urbanization, which can change local weathering patterns. Overall, human activities can both intensify and alter natural weathering processes.
What human activities break rocks?

What forces contribute to the breaking of rocks?
Applied force, if someone is chopping the rock with an axe or hammer.
How does man contribute to rock weathering?
Humans can contribute to rock weathering through activities like mining, excavation, construction, and use of heavy machinery. These activities can break down rocks mechanically or chemically, leading to accelerated weathering processes. Additionally, pollution from human activities can introduce chemicals that can cause rocks to weather more rapidly.

Rocks are broken down by water air and living organisms?
Yes, rocks are broken down through processes like weathering, erosion, and biological activity. Water and air contribute to physical and chemical weathering, while living organisms such as plants and animals can also play a role in breaking down rocks through activities like root growth or burrowing. Over time, these processes can fragment rocks into smaller pieces and contribute to the formation of soil.
What is the origin of salination?
Salination occurs naturally through processes such as weathering of rocks and evaporation of seawater. Human activities, such as irrigation with salty water, can also contribute to salination of soil.
