What are the different types of weathering describe each?

What are the different types of weathering describe each?

Weathering is the breakdown of rocks at the Earth’s surface, by the action of rainwater, extremes of temperature, and biological activity. It does not involve the removal of rock material. There are three types of weathering, physical, chemical and biological.

What are 3 things 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 3 main agents of erosion?

Water, wind, ice, and waves are the agents of erosion that wear away at the surface of the Earth.

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

Factors affecting weathering

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

What are the 5 effects of soil erosion?

Some of the greatest effects of soil erosion include:

1. Loss of Topsoil. Obviously, this is the biggest effect of soil erosion.
2. Soil Compaction.
3. Reduced Organic and Fertile Matter.
4. Poor Drainage.
5. Issues With Plant Reproduction.
6. Soil Acidity Levels.
7. Long Term Erosion.
8. Water Pollution.

What is the good effect of soil erosion?

Environmental Benefits in Three Industries When topsoil erodes, it carries away many of the nutrients needed to grow abundant, healthy crops. As a result, erosion can decrease crop yields by up to 50%.

What are the effects of erosion?

Impacts of erosion

• reduced ability of the soil to store water and nutrients.
• exposure of subsoil, which often has poor physical and chemical properties.
• higher rates of runoff, shedding water and nutrients otherwise used for crop growth.
• loss of newly planted crops.
• deposits of silt in low-lying areas.

What are the causes and effect of erosion?

Water runoff is increased, and run off often carries pollutants with it which negatively impact the surrounding land. Other effects of erosion include increased flooding, increased sedimentation in rivers and streams, loss of soil nutrients’ and soil degradation, and, in extreme cases, desertification.

What are the effects of water erosion?

When the rainwater erodes the soil, it can lead to diminished water quality problems. After the eroded topsoil reaches the water sources, it increases the presence of nitrogen and phosphorous in the water. This results in reduced water oxygen levels and diminished water quality.

What is the most important impact of on site soil erosion?

The main on-site impact of soil erosion is the reduction in soil quality which results from the loss of the nutrient-rich upper layers of the soil, and the reduced water-holding capacity of many eroded soils.
