Erosion vs Weathering
Distinguishing the difference between erosion and weathering becomes easy when you understand these two different processes. Erosion and weathering are natural geological forces of nature that cause the destruction ofrocks并塑造地球的表面。但是，我们可以说，这些过程本质上是相似的，因为它们参与了改变地球表面的地形，但是需要突出一些差异。风化是指由于自然力量将岩石分解为较小的碎片，而侵蚀是一组涉及风，流水和冰运动的过程glaciersthat take along the fragments created by weathering to newer locations.
What is Weathering?
In weathering,large rocks get broken because of the action of weather, but they do not move to a new location. They simply remain next to one another. Weathering is classified as biological,physical and chemical weathering.Physical weathering所有这些过程都导致岩石破裂成较小的碎片，例如碰撞，由于压力或由顶级岩石侵蚀引起的压力释放。由于植物的根部向内生长而发生的破坏被称为biological weathering.化学风化, on the other hand, is a result of water, either through rainfall or from high streams, oxygenation of minerals present in rocks, or when minerals in rocks dissolve completely in water. As a result of all these actions rocks break into smaller pieces.
Here, let us see how one process actually happens. Let us see how physical weathering takes place. You must have seen how there are crevices and cracks on huge stones. When it rains, water gathers in these cracks and crevices. Then, when night time comes, the temperature of the environment drops. As a result of that, the water that is in these small cracks and crevices begin to expand as it turns to ice. In doing so, the rock starts to split. This action repeats for some time, and finally, the rock piece separates itself from the huge rock.
什么是侵蚀？
When the broken up rock pieces remain where they are, the action of wind, water, and melting ice takes some of these small pieces of rocks to new locations. This process is called erosion. Erosion is a set of processes that result in shaping of the landscape as rock pieces are brought down to lower levels by blowing winds, flowing water, and the effects of gravity. The small pieces of rocks that we see around beaches and sides of rivers have origins high up in the mountains. Erosion is the beginning of a larger process. It has four other phases known in order as分离，夹带，运输和沉积. The pieces of rocks and sediments that start travelling with erosion have to settle somewhere. Once they do, that is known as deposition.
侵蚀和风化有什么区别？
•尽管风化和侵蚀都有助于重塑地球的表面，但风化涉及将岩石折断成较小的碎片，而侵蚀是由于这些较小的碎片向新的碎片移动到较新的位置，这是由于风，流动的水和融化的冰再加上重力。
•可以物理风化、有机或化学物质whereas erosion is plain movement of rock pieces from one place to another.
• It is because of both weathering and erosion that we get to see new geological features. We cannot stop weathering from happening. However, to stop erosion from happening people take different actions such as planting trees on hill tops.
Both weathering and erosion are a continuous process that keeps on acting, all the time,on the surface of the earth. In that, first weathering takes place and then the erosion takes the broken rock pieces to new locations. These are natural processes that continue unabated. Both weathering and erosion are constantly at work to reshape the surface of the earth intomountains,valleys,rivers, andplainsthat are known as physical features. These physical features keep on changing on the geological time scale as a result of both these natural geological processes.
