Once the rock is affected by weathering, the process of erosion causes bits of rock and earth to be carried away from their original location. A new, third level of content, designed specially to meet the advanced needs of the sophisticated scholar. Temperature changes cause pieces of rock to flake away from the surface. A fast-flowing stream can carry large rocks while a slow moving stream might only be able to carry very small things like clay. The Amazon accounts for about one-fifth of the world's total river flow. These forces also move bits of rock and earth to new places. A wave can wash up onto the surface of rock or soil and then carry away pieces of material as it flows ba… Deposition is when those sediments are deposited, or dropped off, in … Introduce kids to coastal erosion with this simple beach erosion demonstration and activity. The huge masses of ice called glaciers also cause erosion. 2. It makes the soil weaker. Erosion is the general term that means the wearing down of landforms, including the toughest, tallest mountains. The size of earth materials that can be moved by water depends on how fast the water is moving. Erosion is the gradual destruction and removal of rock or soil in a particular area by rivers, the sea, or the weather. Soil erosion can remove soil, leaving a thin layer or rocky soil behind. It is when the soil is broken down into smaller pieces and they become loose in the earth’s surface. The process by which soil and rock is removed from one area of the Earth through natural causes such as wind, water, and ice and transported elsewhere is called erosion. The Nile, perhaps the world's longest river, carries much less sediment than the others because, part of the way, it runs through less fertile regions than the other great rivers. Erosion is the process that breaks things down. The sediment discharged by the gigantic mouth of the Amazon stains the sea brown for hundreds of miles out to sea. These processes are called weathering. These particles rub against the riverbed and wear away more rock and soil. All these materials are called sediments. A wave can wash up onto the surface of rock or soil and then carry away pieces of material as it flows back into the ocean or lake. When the ground rises the whole weather system can also be changed including local sea levels, wind strength and direction, rainfall and more.

Most of the energy that makes erosion happen is provided by the Sun. An actively eroding rill on an intensively-farmed field in eastern Germany. Hands-on science experiments are one of our favourite rainy day activities.

Weathering can be caused by wind, water, ice, plants, gravity, and changes in temperature. This kind of erosion helped to carve the Grand Canyon in the southwestern United States. Tectonics builds up height by surface and rock uplift, and climate controls the erosion. Glaciers scrape away parts of the rocks and the earth below as they creep down mountain valleys.

Erosion, weathering, and deposition therefore work together to change existing landforms and create new landforms. Erosion starts with weathering. 3. Cold weather causes water inside tiny cracks in rocks to freeze. If that broken-down material gets moved at all by water, wind or ice, then erosion has occurred. The Amazon has by far the largest waterflow, with an average discharge greater than the next seven largest rivers combined. Processes called erosion, mass movement and weathering break down and remove material from the coast. Valley erosion is occurring due to the flow of the stream, and the boulders and stones (and much of the soil) that are lying on the stream's banks are glacial till that was left behind as ice age glaciers flowed over the terrain.
