How does weathering shape landforms? Weathering is the breakdown or loosening of surface minerals of rocks after they are exposed to weathering agents such as water, oxygen air , organic and inorganic chemicals and temperature. Weathering occurs in place in situ. Weathering is the event that comes before erosion sets in. Weathering is responsible for many wonderful landforms usually seen in coastal areas. Erosion or Weathering? It is important not to confuse erosion with weathering.
Erosion is the process of land, soil or rock being gradually worn away by natural elements, such as water or wind. Landforms can be created and destroyed by erosion. Landforms that are created by erosion are called fluvial erosion landforms. As water passes across land, it carries with it sediment and other forms of natural debris. Over time, the accumulation of this sediment and debris create deposits, which eventually become landforms. Examples of fluvial erosion landforms include sandbars, flood plains and levees. The same creative force that builds landforms also destroys them.

Weathering and erosion slowly chisel, polish, and buff Earth's rock into ever evolving works of art—and then wash the remains into the sea. The processes are definitively independent, but not exclusive. Weathering is the mechanical and chemical hammer that breaks down and sculpts the rocks. Erosion transports the fragments away. Working together they create and reveal marvels of nature from tumbling boulders high in the mountains to sandstone arches in the parched desert to polished cliffs braced against violent seas.
This section introduces you to weathering and erosion, both important parts of the rock cycle. You will learn how different rocks are weathered and eroded and the implications of this weathering. The footprints that astronauts left on the Moon will be there forever. This is because the Moon has no atmosphere and, as a result, has no weathering. Weathering is one of the forces on Earth that destroy rocks and landforms. Without weathering, geologic features would build up but would be less likely to break down.
The water cycle process looks like this:. Without this process, weathering, erosion, and deposition would have a difficult time occurring on Earth. Weathering Process The weathering process occurs when rocks are exposed to the hydrosphere water and atmosphere air. See page 6 of the Earth Science Reference Tables explains the sizes of each of these sediments. Physical Weathering Physical weathering -- when rocks are broken in to smaller pieces without changing the chemical composition of the rock.
Weathering is the process where rock is dissolved, worn away or broken down into smaller and smaller pieces. There are mechanical, chemical and organic weathering processes. Organic weathering happens when plants break up rocks with their growing roots or plant acids help dissolve rock. Once the rock has been weakened and broken up by weathering it is ready for erosion. Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity. Mechanical weathering physically breaks up rock.
