Effects of Erosion

Physical erosion causes rocks to become smaller or smoother through changes to their physical properties but not chemical composition. Water, wind, ice, and thermal processes are major agents of erosion on Earth. Water erosion in the form of rain, rivers, floods, lakes, and oceans carries away soil and sediment. Wind erosion transports dust, sand, and ash long distances. Ice erosion occurs through glaciers slowly moving across land and transporting materials. Thermal erosion results from warming permafrost breaking off in large chunks along coastlines.

5 Effects of Erosion

Physical Erosion

Physical erosion describes the process of rocks


changing their physical properties without changing
their basic chemical composition. Physical erosion
often causes rocks to get smaller or smoother. 

Erosion by Water

Liquid water is the major agent of erosion on Earth.


Rain, rivers, floods, lakes, and the ocean carry away
bits of soil and sand and slowly wash away the
sediment.

Erosion by Wind

Wind is a powerful agent of erosion. Aeolian (wind-


driven) processes constantly transport dust, sand, and
ash from one place to another. Wind can sometimes
blow sand into towering dunes..

Erosion by Ice

Ice, usually in the form of glaciers, can erode the earth


and create dramatic landforms. In frigid areas and on
some mountaintops, glaciers move slowly downhill
and across the land. As they move, they transport
everything in their path, from tiny grains of sand to
huge boulders. 

Thermal erosion 

Thermal erosion describes the erosion


of permafrost along a river or coastline.
Warm temperatures can cause ice-rich permafrost to
break off coastlines in huge chunks, often carrying
valuable topsoil and vegetation with them.
