What are the factors that influence the rates of weathering and erosion Class 7?

What are the factors that affect the rate of erosion?

Major factors that affect the amount of erosion are soil cloddiness, surface roughness, wind speed, soil moisture, field size, and vegetative cover. A discussion of each follows. The cloddiness of a given soil largely indicates whether the wind will erode it.

What are 5 factors that influence weathering?

Factors affecting weathering

  • rock strength/hardness.
  • mineral and chemical composition.
  • colour.
  • rock texture.
  • rock structure.

What are the three factors that affect the weathering rates?

Factors such as surface area, rock composition, and location influence the rate of weathering. water, the faster the rock will break down. A greater surface area allows chemical weathering to affect more of a rock.

What are 4 factors that affect the rate of erosion?

Climate, soil properties, vegetation, soil cover, and land management practices are factors that influence both water and wind erosion.

What is erosion and factors affecting erosion?

Factors such as rainfall, runoff, wind soil, slope, plant cover and presence or absence of conservation measures are responsible for soil erosion. But mainly three following factors affect the erosion. 1. Energy: … in case of water erosion and wind breaks or shelter belts incase of wind erosion.

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.

What are the factors that cause 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 six factors that affect the rate of weathering quizlet?

The causes of mechanical weathering include freezing and thawing, release of pressure, plant growth, actions of animals, and abrasion. The causes of chemical weathering include the action of water, oxyen, carbon dioxide, living organisms, and acid rain.

How is erosion different from weathering?

What is the difference between weathering and erosion? Weathering is the process of decomposing, breaking up, or changing the color of rocks. … So, if a rock is changed or broken but stays where it is, it is called weathering. If the pieces of weathered rock are moved away, it is called erosion.
