Weathering, Erosion and Deposition

Weathering, Erosion and Deposition Nature is always changing. Those changes are callednaturalevents. Somenaturaleventshappen quickly. Think of a fire that starts when lightning strikes a tree. Othereventsoccur slowly, such as when rocks are worn down over hundreds of years. This happens because of weathering and erosion.Weathering is what happens when a part of a rock is loosened. Parts of rocks are usually loosened by nature. Erosion (ih-ROH-jzun) happens after weathering. It is the process of moving water, moving ice, or wind carrying away a part of a rock.Moving water can cause weathering and erosion. Have you ever seen waves crash against rocks on the shore? The water can chip off small pieces of rock and carry them away. As more waves hit the rocks, more pieces are chipped off and carried away. Because of this, the rocks get smaller and smaller over time.Moving ice can cause weathering and erosion. Some mountains have solidsheetsof ice near the top. During warmer weather, a bit of ice melts. Then thesheetof ice may move slowly down the mountain. As the solid ice moves, it scrapes rocks, breaking off pieces. Then the pieces are taken away by the moving ice.Wind also causes weathering and erosion. Wind can blow sand and dirt. It can carry the dirt far away. In some places, strong wind will push sand against rocks. Over a long period of time, the wind wears down those rocks. Weathering and Erosion Sort the actions into the correct column. Weathering the breaking down of rocks mountain top slowly becoming more rounded ice causing cracks in the sidewalk as it melts and freezes changing rock to sediment Both changes Earth's surface Erosion waves moving sand along the beach river carrying sediment to a new location wind blowing desert sand This rock can be found in the warm ocean waters off the coast of Australia. It has been named "Split Apple Rock". What caused this rock to split?
