Which of the following helps prevent erosion?

Surface cover and runoff. Surface cover is a major factor to control erosion because it reduces the impact of raindrops falling on bare soils and wind removing soil particles. It also reduces the speed of water flowing over the land. Erosion risk is significantly reduced when there is more than 30% soil cover.

How does weathering affect buildings?

Chemical Weathering

In the process of carbonation, rainwater and carbon dioxide in the atmosphere combine to form carbonic acid. This carbonic acid dissolves minerals within the rock, weakening the structure and resulting in damage and wear.

How does ice cause weathering?

Weathering From Ice

The ice expands and forms wedges in the rock that can split the rock into smaller fragments. Ice wedging usually occurs after water repeatedly freezes and melts inside small rock crevices over time. You can see the result of this type of weathering on street sidewalks in the winter.

How are rocks affected by acid rain?

Acid rain slowly dissolves rocks due to chemical reactions between the acid and the minerals in the rock. Differential Weathering: Softer, less resistant rocks wear away at a faster rate than more weather resistant rocks. More exposure to acid rain results in more rapid weathering.

Can acid rain create UV light?

The interactions between acid rain, ultraviolet (UV) radiation and climate change can magnify the impacts of acid rain. For example, because acidity reduces the amount of dissolved organic matter in lake water, acidic lakes are clearer and therefore more vulnerable to the effects of increased UV levels.

What is the preservation of the environment?

Preservation protects the environment from harmful human activities. For example, conserving a forest typically involves sustainable logging practices to minimize deforestation. Preservation would involve setting aside part or even all of the forest from human development.

How does freezing water cause the weathering of rocks?

Freeze-thaw Weathering

When water seeps into rocks and freezes, it expands and causes the rock to crack. When water transforms from a liquid state to a frozen state, it expands. Liquid water seeps into existing cracks in the rock, freezes and then expands those cracks.

What is dissolution weathering?

Dissolution is the most easily observed kind of chemical weathering. Over time, the action of slightly acidic solutions on the rock can leave pits and holes, and it can act to slowly enlarge and widen preexisting fractures.

How do rocks become soil?

Answer and Explanation: Rocks turn into the soil through the process of weathering. Weathering is when rocks are broken down into smaller pieces. Physical weathering occurs when natural forces, such as water or wind, physically break apart the rock without chemically changing it.

What are examples of weathering?

Weathering is the wearing away of the surface of rock, soil, and minerals into smaller pieces. Example of weathering: Wind and water cause small pieces of rock to break off at the side of a mountain. Weathering can occur due to chemical and mechanical processes.

How does weathering affect monuments?

Weathering is the process by which stones and metals are broken down over time. Because water expands when it freezes, it widens the crack in the monument and can eventually fracture and break off pieces, altering the shape of the monument and necessitating costly restorations and repairs.

How do human activities affect the rate of rocks weathering?

Weathering is a natural process, but human activities can speed it up. For example, certain kinds of air pollution increase the rate of weathering. Burning coal, natural gas, and petroleum releases chemicals such as nitrogen oxide and sulfur dioxide into the atmosphere.

How can landslides and soil erosion be prevented?

The most effective, natural way to control soil erosion on slopes is to plant vegetation. Not only will vegetation help to slow down raindrops as they fall, the roots of the plants will also help to hold the soil together, making it harder for water to wash it away.

How do plants help prevent erosion?

Plants also help absorb some of the water in the soil. These effects make it harder for water to wash the soil away. Plants also help reduce erosion in other ways, such as breaking the wind that might blow dry topsoil away.

How can we prevent soil erosion Class 9?

Answer: Preventive methods of soil erosion (i) Afforestation Planting more trees reduces soil erosion. (ii) Contour Ploughing Ploughing land in furrows across the natural slope of the land helps trap water and prevent the washing away of top soil along with it.

How can earthworms cause weathering?

Did you know that earthworms cause a lot of weath- ering? They tunnel through the soil and move pieces of rock around. This motion breaks some of the rocks into smaller pieces. It also exposes more rock surfaces to other agents of weathering.

What is salt weathering?

Salt. weathering is a process of rock disintegration by salts that have accumulated at. and near the rock surface. It is the dominant weathering process in deserts. especially in coastal and playa areas where saline groundwater may be close to.

How does gravity cause weathering?

Gravity causes abrasion as a rock tumbles down a mountainside or cliff. Moving water causes abrasion as particles in the water collide and bump against one another. Strong winds carrying pieces of sand can sandblast surfaces.
