What are 2 causes of weathering?
Plant and animal life, atmosphere and water are the major causes of weathering. Weathering breaks down and loosens the surface minerals of rock so they can be transported away by agents of erosion such as water, wind and ice. There are two types of weathering: mechanical and chemical.
What are the factors that influence the rates of weathering and erosion?
Rainfall, heat and moisture are the 3 main factors which affect the rate of weathering and soil erosion. Weathering happens more quickly in hot and wet climates. Wind is another major factor affecting soil erosion.
Which are the factors that affect the rate of erosion?
The most important erosion factors include the climatic, hydrological, topographic, soil, geological and vegetation conditions, as well as the economic and technical and the socioeconomic conditions of the human society.
Where is physical weathering most common?
Where does it occur? Physical weathering happens especially in places places where there is little soil and few plants grow, such as in mountain regions and hot deserts.
What are the factors of physical weathering?
1.1. Physical weathering can occur due to temperature, pressure, frost, root action, and burrowing animals. For example, cracks exploited by physical weathering will increase the surface area exposed to chemical action, thus amplifying the rate of disintegration.
What is the main difference between physical and chemical weathering?
Physical, or mechanical, weathering happens when rock is broken through the force of another substance on the rock such as ice, running water, wind, rapid heating/cooling, or plant growth. Chemical weathering occurs when reactions between rock and another substance dissolve the rock, causing parts of it to fall away.
Which is faster chemical or physical weathering?
Physical weathering is a gradual process, though faster than chemical weathering. Chemical weathering entails transformation and modification of mineral components and thus, it the entire process is slower when compared to physical weathering. Minerals inside the rock do not dissolve completely.
What is the difference between physical weathering and erosion?
Erosion and weathering are the processes in which the rocks are broken down into fine particles. Erosion is the process in which rock particles are carried away by wind and water….Erosion vs Weathering.
