What is the difference between erosion and corrosion? What does erosion mean?

The former can reach the interior of the object to form destruction, while the latter is aimed at the destruction of the surface. The intensity of the destruction is not the same.

The meaning of corrosion is as follows:

1.Through chemical action, the object is gradually damaged and destroyed: corrosives, this plastic can resist the corrosion of acids and alkalis.

2.Bad thoughts and behaviors affect people's minds and make them gradually degenerate and become bad: strictly guard against the corrosion of rotten thoughts.

Corrosive sentences: 1. The desire for money is like a strong acid that corrodes people's hearts.

2. The reporter saw this case in the hospital, because the metal case has been partially corroded and deformed and covered with red rust after being in the nasal cavity for too long, but the silver-gray metal inlays of the case are still clearly visible.

3. Money is not only a kind of wealth, but also a corrosive agent of life.

4. Phenolic foam is a new type of thermal insulation material, which has the characteristics of heat resistance, acid corrosion resistance, excellent flame retardancy, low smoke and non-toxicity, but has the shortcomings of brittleness and easy slag dropping.

5. But in order to protect the jet engine from seawater corrosion, it should be installed on the top of the aircraft. In this way, the splash of water during take-off or landing will not hit the air intake.

6. Cracks, corrosion and loose coordination and other faults are often produced in the process of use of engineering structures.

8. Further inspection found that the fractured part of the sounding pipe had been seriously corroded.

9. If memories are as hard as steel, then should I smile or cry, and if steel corrodes like memories, then is this a city of joy or ruins?

10. The presence of heterotrophic bacteria and other microorganisms in the soil also has a comprehensive effect on corrosion.

The weathered rock is abrasively abrased by wind, water, ice or gravity, and the process of transportation is called erosion; Under the action of long-term wind and sun, rain erosion, biological destruction, etc., the process of surface rock fragmentation is called weathering. Give it a thumbs up!! It is the next volume of science in the sixth grade.

Erosion: Gradual destruction or corrosion: Rocks are weathered by natural erosion to resist the erosion of bad ideas.

synonyms: corrosion.

Antonyms: protect, protect.

First, the classification of the two is different:

1. Classification of water erosion: ocean erosion, river erosion, etc.

2. Classification of flowing water dissolution: water stagnant dissolution in the upper layer of karst, karst diving dissolution.

Second, the overview of the two is different:

1. Overview of water erosion: erosion involves the movement and disintegration of rocks and minerals through media such as water, ice, wind and gravity. Erosion can be divided into mechanical ablation and chemical ablation.

2. Overview of the dissolution of flowing water: the most hidden and typical landform formed under the dissolution of dissolved water is karst (karst) landform. For example, Guilin, Guangxi, a famous tourist attraction in China, has various karst landform types such as karst caves, stone forests, stone stalactites, and dissolution buckets formed by the dissolution of flowing water all over the region.

3. The reasons for the formation of the two are different:

1. The cause of the erosion of flowing water: the erosion of flowing water is more powerful and common, about 90% of the continental area is under the control of the erosion of the Bilu Hall of flowing water, precipitation erodes the surface of the earth, the flow of valleys and rivers, widening and deepening the valley bottom and riverbed, and the flowing water on the slope washes the entire slope surface, making it tend to be broken.

2. Causes of the dissolution of flowing water: The dissolution kinetics experiments of carbonate rocks composed of different minerals with dilute acetic acid as the medium under different temperature and pressure conditions of buried diagenesis by using the mobile liquid phase water-rock reaction experimental device show that the degree and rate of dissolution of carbonate rocks increase with the increase of burial depth.
