The gradual breaking down of an object or geographical mark is called erosion. There are three main types of erosion: Physical, Chemical, and Homo-Destructus.

The most common of the three, is Physical Erosion. This is caused by water (rain or waves), snow, sand, or dust which ebb away on almost any natural land mass. Depending on the climate or biome of the region in which the weathering takes place, the erosion method will differ. Waves and currents dominate in the withering down solid of rock walls against the ocean. Often, when this happens, beautiful arches, stacks, and sea caves are formed in areas where the water is more collective such as in bays or gulfs. Sand and other small pieces of material can batter against mountains, monuments, and landmarks. Slowly, this whittles them to sizes of small hills or even very small buttes and ridges. While this is one of the slower erosion processes, it is the often most seen, as there is more land, then coastline. Trees and rivers also provide a great environment for erosion. For example, in the Grand Canyon or Zion National Park, a perfect river cut right through vast plateaus resulting in monumental canyons. This is the cause of the same water erosion as on the coast except a river keeps flowing making a snake-like appearance. Not only does the water chip away at the walls of streams, but small bullet pebbles bounce in a cataclysmic way also breaking rocks. River erosion often are the most beautiful and largest of all. Trees, surprisingly also destroy earth and rocks. Oaks, Sequoias, and larger trees can do so by simply growing at immense speeds. Their thick roots pry open and rip through rocks causing them breakage. This same ripping motion happens with water when it seeps into rocks and cracks them in half. Since solids take more space than liquids, the rock’s insides get destroyed when the water crystallizes and freeze. Erosion is very brutal in this sense.

The second type of natural weathering is Chemical Erosion. It is very different from physical erosion because it is caused by temperature and humidity. Water is important to this because it is able to break down loose and water soluble minerals like calcite. The water can also steady and change the temperatures of an object by a few degrees. In science, a few degrees makes a tremendous change in the surrounding area. The temperature also effects the moisture of the surrounding air, thus making the entire water factor a chain reaction. Not only does water play in this but different liquids, toxics, and even air can change the formations and development of erosion. One example of chemical erosion would be to put oil on a stalagmite and in a few years he stalagmite would stop growing, and then it would begin to deteriorate slowly from the bottom up because of the oil separating the calcite and water. The long pole would dry up and become flimsy.

The final and least commonly known of form of erosion is the Homo-Destructus. This is Latin for the modern English phrase, “self destruction”. There are many notable examples of this type of erosion. When an animal or person walks over the same piece of land for a long time, a path is created. Another example is when mountain climbers hike and scale steep gorges and slowly knock off chunks and bits of rock. The issue of global warming and industry is the largest and most well-known of all Homo-Destructus. These are some of the examples that are commonly found.
