Both.
Erosion is only a destructive force!Erosion is a destructive force. Destructive erosion is where you take part of one land form away to create a new one. An example of a destructive force is a u-shaped valley. This u-shaped valley use to be a v-shaped valley until ice eroded it away. The ice cuts into the rock and curves it out to form a u-shaped valley.Hope this helped!
Wind erosion is the movement of material by the wind and occurs when the lifting power of moving air is able to exceed the force of gravity and the friction which holds an object to the surface. The movement of sand dunes is an example of wind erosion.
Wind erosion is the erosion of sediment by wind. This occurs when the lifting power of moving air is able to exceed the force of gravity.
Wind erosion is the act of the winds having one opposing force moving against another. Wind erosion carries fine particles of clay and dust from one area to another.
Wind erosion is worst when soil is dry, damaged, and exposed. When farmland is tilled but not planted, or tilled, planted, and the seedlings die out from lack of moisture, the ground is perfect for destructive wind erosion. A lack of natural barriers to wind at ground level worsens the problem; rows of tall trees like poplars can help stop wind erosion.
Canyons are both constructive and destructive. The constructive element is one of erosion by both wind and water in their creation which takes place over a long period of time.
It is constructive
Erosion
Wind
wind is an agent of erosion which causes sheet erosion
sand dunes
They are destructive because it breaks down the river by wind, water, and ice abrasion a mechanical/physical type of weathering.
Friction causes erosion through wind or water.
constructive forces change earth by building up land or mountains from the earthquakes. Also, volcanoes spit out lava which turns into new rock. Destructive forces are basically weathering of the land and erosion from water, ice, wind, temperatures, or other natural stuff.
because of the sand and dirt that flies in the wind, thus over time (with enough speed in the wind of course...) the rock or material will eventually erode. you should know this, because tis be sparta my friend. tis. be. sparta.

A motive force such as wind or water .
