are erosion constructive or destructive?
529255
Landforms are a result of a combination of constructive and destructive forces. Collection and analysis of data indicates that constructive forces include crustal deformation, faulting, volcanic eruption and deposition of sediment, while destructive forces include weathering and erosion.

Gravity, running water, glaciers, waves, and wind all cause erosion. The material moved by erosion is sediment. Deposition occurs when the agents (wind or water) of erosion lay down sediment. Deposition changes the shape of the land.

Weathering and erosion are processes by which rocks are broken down and moved form their original location. They differ based on whether a rock's location is changed: weathering degrades a rock without moving it, while erosion carries rocks and soil away from their original locations.

Corrosion, therefore, is a chemical-like phenomenon that modifies the nature of the material that corrodes, changing its chemical composition. Erosion, on the other hand, is a physical phenomenon which consists in the fact that certain natural phenomena (wind, rain, movement of glaciers ...)

Weathering is when rocks are broken down (chemically or mechanically) and erosion is when sediment is carried away. What is the difference between erosion and deposition? Deposition is when the sediment settles out of the water , wind or ice that is carrying it. You just studied 32 terms!

Erosion. The main difference between weathering and erosion lies in where the process takes place. Weathering degrades a rock without changing its location. Erosion, on the other hand, causes rocks -- or particles of rock -- to be carried away from their original locations and deposited elsewhere.

When the smaller rock pieces (now pebbles, sand or soil) are moved by these natural forces, it is called erosion. So, if a rock is changed or broken but stays where it is, it is called weathering. If the pieces of weathered rock are moved away, it is called erosion.

CANYONS, A DESTRUCTIVE FORCE A canyon is a destructive land form. Canyons are made by weathering. Weathering is the process of breaking down rock into smaller sediment.

Erosion is the transport by wind, water and ice of soil, sediment and rock fragments produced by the weathering of geological features. Sedimentation occurs when eroded material that is being transported by water, settles out of the water column onto the surface, as the water flow slows.

Erosion is the process where rocks are broken down by natural forces such as wind or water. There are two main types of erosion: chemical and physical. Chemical erosion occurs when a rock's chemical composition changes, such as when iron rusts or when limestone dissolves due to carbonation.

Soil Erosion means removal of the soil (usually Top Soil) by erosional forces such as wind and water. ... Similarly, soil removed from one region is deposited at other places. Land Degradation means temporary or permanent reduction in the biological or economic productive capacity of the land resource base.

Erosion occurs when rock particles are moved by an external force or agent. The agents of erosion are ice, water, wind, waves and gravity. The degree to which erosion occurs depends on the slope of the land, amount of rain or snow, wind and looseness of the rock and soil.

Erosion cuts away at existing layers of the earth. Erosion creates sediments that are transported by wind and water. Deposition is a natural result of erosion the sediments being transported have to be deposited somewhere. Deposition is where the sediments created by erosion are deposited.
