Difference Between Erosion and Corrosion (With Table)

Corrosion and Erosion both are a reaction in which a substance undergoes a change and forms a different substance. There are differences between these two and makes it an amazing scientific phenomenon. The changes seen in these processes can be chemical or natural. Erosion only occurs on the surface of the land. The metals normally undergo corrosion. The metal surface gets changed, and actually, the metal surface gets wasted. This process is irreversible.

Erosion vs Corrosion

The difference between Erosion and Corrosion is Erosion is a natural process in which the material changes its actual nature, whereas, in Corrosion, the material directly changes its chemical composition. Erosion occurs through natural agents, whereas Corrosion occurs due to corrosive agents. Erosion consists of various processes like weathering, dissolution, and transportation.

Erosion occurs naturally. It is a natural process in which the material gets carried away from one place to another. The natural forces work as agents in erosion. It is a physical process. It carries the particles to another location. Natural agents are wind, ice, and water.

Corrosion is a process in which the substance changes its composition during oxidation. It is an electrochemical process. The corrosion process occurs during oxidation. It takes place under atmospheric oxygen. The material gets transformed into a different chemical compound which is known as Rust. Corrosion consists of the galvanic, crevice, and some other agents.

Cos'è l'erosione?

A natural process that carries away the particles from one place to another. There are three types of erosion which are wind erosion, ice erosion, and water erosion. Erosion which happens due to ice, is shifting glaciers from one place to another. Erosion carries away the bare land particles, dry leaves loose particles of Earth’s surface.

Erosion is just the movement of particles. The impact of erosion is determined by climate, topography, and vegetation cover. It is a natural process in which the material gets carried away from one place to another. The natural forces work as agents in erosion. It is a physical process. It carries the particles to another location.

Natural agents are wind, ice, and water. There are preventive measures for Erosion. Land reform techniques can be used. Plantation, terracing, and protecting vegetation cover can prevent Erosion. Erosion only occurs on the surface of the land. Erosion consists of various processes like weathering, dissolution, and transportation.

The external forces lead to Erosion. It occurs naturally. The natural agents drag the particles or dissolve in the water. It may modify the actual particle. Acid Rain is also a reason which makes erosion. It destroys the topsoil, due to which the particles of the soil become loose. It gets easily carried away by the wind particles.

What is Corrosion?

Corrosion is a chemical process in which an actual component gets transformed. It corrodes, and the chemical composition of the component gets changed. It is an electrochemical process. The material gets changed in its oxidation state. It then gets mixed with another compound.

The oxidation takes place under atmospheric oxygen. The metals normally undergo corrosion. The metal surface gets changed, and actually, the metal surface gets wasted. This process is irreversible. The agents which lead to corrosion are sulfates and oxygen. There are four types of Corrosion.

Localized, galvanic, general attack and stress cracking. The metals can have weakened cracks which are known as stress cracking. The corrosion process occurs during oxidation. Corrosion consists of the galvanic, crevice, and some other agents. It takes place under atmospheric oxygen. The material gets transformed into a different chemical compound which is known as Rust.

Localized corrosion emphasizes some portion of the metal. The type of metal and environmental conditions influence corrosion. Corrosion occurs on polymers, metals, or ceramics.

The metals should be coated so that the metal does not changes its actual composition and gets chemically changed due to atmospheric oxygen. Corrosion is led by corrosive agents. Metals lose their properties in the presence of atmospheric oxygen.

Main Differences Between Erosion and Corrosion

  1. Erosion is a natural process, whereas Corrosion is a chemical process.
  2. Erosion mainly happens on the surface of the land, whereas Corrosion happens on the metal surface.
  3. Erosion is led by natural agents, whereas Corrosion is led by corrosive agents.
  4. Erosion includes weathering, transportation, and dissolution, but Corrosion consists of a galvanic crevice, selective leaching, and others.
  5. Erosion can be prevented using plantation or terracing, but Corrosion can be prevented by applying a coat on the metal surface.
