Difference between weathering and erosion

Main difference

The main difference between weathering and erosion is that weathering means a change in wind or temperature, while erosion means the movement of rocks, soils, etc. to a new location.

Weathering versus erosion

Weathering occurs in a specific place. Erosion causes the movement of objects to a new location. Weathering can be a physical or chemical change in different objects due to weather. Erosion occurs mainly due to the various actions of wind, water, etc. The weathering process can result in the formation of sharp, rounded edges of the rocks. The process of erosion results in the slow migration of the dunes from time to time, and a case of flooding rapidly the migration of the dunes.

Weathering causes the degradation of rocks without moving from the original place. Erosion causes the degradation of rocks and soil sediments by removing the soil or rocks from their original location. Weathering can lead to the erosion process after reaching a stage. However, erosion cannot lead to the weathering process.

The main cause of weathering are different atmospheric factors. The main cause of erosion are different human activities. Weathering only refers to the breakdown of rocks and changes the structure and shape of rocks. Erosion refers to the general change of location. Weathering is also said to be a process by which rocks dissolve. Erosion is the process through which rocks are transported.

Weathering is related to the decomposition of the earth. Erosion is related to the settlement of the broken pieces. Weathering is under the action of biotic and abiotic agents. Erosion is under the action of mechanical agents such as water, etc. Humification is the effect of the weather. Erosion is the cause of glacier activity or gravity, glacier activity, etc.

What is weathering?

The weathering process consists of alternating or degrading the rocks by different methods. Weathering is about the breakdown of rocks and minerals. It occurs with no or as well as little movement. Most of the erosion occurs in the same place. Landscapes are also the result of weathering along with erosion. Plants and animals also show biological weathering and can also create chemical weathering by releasing acidic components. Mainly, weathering is about two different types.

One type is physical weathering. In physical weathering, only the physical structure of rocks or other material is affected and it begins to break down. For example, when the rain falls on the rocks in the winter season, then the water seeps into the holes in the rocks and, due to the cold weather, freezes in it, after which the holes begin to expand and eventually they break and separate from the rocks. rock. This process can also occur in the case of salt accumulation and trees. Physical weathering also occurs when rocks rub against each other due to water and wind and soften their surfaces.

Chemical weathering is another form of weathering. Due to chemical weathering, chemical changes occur in the rock. Such chemical changes cause rocks to become softer or sometimes brittle. For example, during chemical weathering, an iron mineral present in rocks reacts with oxygen and turns into oxide. Sometimes chemical weathering is the result of acid rain. Acid rain seeps from the calcium mineral in marble, milestones, and rocks. Physical weathering is also claimed to be the result of chemical weathering.

What is erosion?

Erosion is a continuous and permanent removal of rock fragments and softening to different places, usually downhill as they are carried through the water. Material transport is an important feature of the erosion process, which is carried out mainly with the help of air, water, etc. Erosion damages the rocks and removes them from the original site. Erosion causes mechanical disturbances such as rock fracture, corruption and disaggregation, etc.

Erosion is of several types that are distinguished from each other by the procedure of transporting rocks, stones, and even soil from their original location. Water is the main source that is used as a force to transport material and causes erosion. Sometimes different rivers and canals carry rocks, fragments, and soil, along with their banks. The “Grand Canyon” is basically the result of this type of erosion. It takes about a million years. This type of erosion is also taking place in the ocean due to the movement of water and waves; it is responsible for transporting dust, ash and rock particles from shore rock.

These types of erosion can also move large amounts of such particles to create massive dunes away from the source. In different parts of the world, ice erosion is rare, but it is effective because it can move extremely large rock, which is not possible by other erosive forces. With the help of ice as an erosive force, huge rocks can easily be transported several miles from the original site. Some geologists also said that erosion is a mechanical phenomenon.

Key differences

  1. Weathering is a set of processes to break up rocks, while erosion is a set of processes to loosen the rock or soil to settle downhill or in the direction of the wind.
  2. The change of location is not a necessary weathering process; on the other hand, changing the location of an object is necessary for erosion.
  3. Weathering is the result of atmospheric conditions; conversely, erosion is the result of wind, water, humans, etc.
  4. The weathering process does not involve the transfer of objects; on the other hand, erosion involves the transfer of objects.
  5. Weathering takes place at the original site of the material, while erosion takes place at different locations on the material.
  6. Weathering is only a contributing process, although erosion is a general process.
  7. Weathering is a small process compared to erosion and it is a large-scale process.
  8. Weathering is a couple of chemical processes with a physical process. However, erosion is a mechanical process.
  9. Weathering is a less complex process compared to erosion, which is a complex and slow process.
  10. Weathering occurs when rocks break apart; on the other hand, erosion occurs when broken rock moves from that site.

Final Thought

It is concluded that weathering is about the decomposition of material and erosion is the displacement of material.
