Once weathering breaks apart rocks, deposition transports their components to another place – whether close by like on a riverbank or further away like in another country.
Deposition is the process by which gas changes directly to solid without passing through liquid form – this is how frost forms on windows.
Weathering
Weathering, or the process of breaking rocks and minerals down into smaller pieces, is caused by wind, water, ice, plants, animals and changes in temperature. Weathering breaks rocks down into sediments like sand and pebbles which then can be carried away by erosion from their original locations.
Mechanical weathering occurs when rocks rub together against each other or themselves, creating frictional heat which leads to mineral formation such as calcite and amorphous silica; these minerals coat sediment together into solidified rocks called lithification.
Time of exposure plays a key factor in weathering and erosion risk for rocks. Rocks buried beneath other rocks such as lavas tend to be less vulnerable to weathering than those exposed constantly to the elements.
Weathering and erosion of Earth’s rocky landscape have played a large part in creating canyons such as the Grand Canyon. Over millions of years, weathering and erosion carved its cliffs, gorges and peaks into this natural marvel – processes which continue to alter it today.
Erosion
Erosion, the process of breaking down and eroding rocks and soil, occurs on every continent worldwide and occurs due to factors like wind, rain, ice or gravity moving rocks or soil from one location to another; living organisms also play a part in erosion on Earth’s surface. Erosion has an immense effect on our environment – altering mountain ranges, valleys and river courses dramatically over time.
Erosion can easily be confused with weathering, yet there are a few differences that distinguish them: Weathering refers to the physical breakdown of rock material while erosion involves transporting it along its course. Weathering takes place only where particles can be easily picked up and moved by hand while erosion does not rely on this for its effect.
Liquid water is one of the primary agents of erosion, along with wind and ice. Wind can erode by blowing rocks away while glaciers transport large rock debris as well as fine sediment particles. Erosion may also occur from moving waters such as rivers or estuaries, where their current can scour sediment from their bottom layer before transporting it downstream and depositing it elsewhere.
Deposition
Deposition is an informal testimony taken under oath outside of court which allows parties to ask witnesses who will testify at trial a series of questions in preparation for trial. A court reporter records the testimony for future use in court proceedings. Depositions play an essential part of discovery process and can help level the playing field between opposing sides, while also being helpful for witnesses who may struggle recalling details clearly when giving testimony at trial.
Witness depositions can have a substantial impact on a case if they are either evasive or dishonest with answers given. This gives opposing parties a sense of how the witness might perform at trial and can influence them to settle for less than they might otherwise receive. Their credibility can have such an effect, which is why witnesses must prepare thoroughly prior to attending their depositions.
Bring an original copy and three copies of any documents being used during a deposition to ensure there will always be one for reference in case there is a dispute. Arrive 15 minutes early so you have time to find restroom facilities and settle into your seat before starting the deposition itself.
