Weathering and Erosion Created by: Madi Solomon and Victoria Page

What is weathering? Weathering is the breaking down of rocks, soil, and minerals. It also breaks down artificial materials through contact with the Earth’s atmosphere. In order to prevent the loss of more topsoil, plant erosion- control plants and use no-till planting practices.

What is erosion? Erosion is the process in which soil and rock are removed from the Earth’s surface by natural processes such as wind or water flow and then transported and deposited in other locations. To prevent erosion cover plants, applying mulch to flower beds, build surface runoff barriers, use contour farming when farming on hilly areas, and try terrace farming and gardening.

Causes of erosion and weathering Causes of weathering and erosion are rain fall, acid rain, wind, traffic, water erosion, and glaciers. erosion erosion weathering

The Factors Controlling the Rate of Erosion Precipitation and wind speed Soil erosion and composition Vegetation cover Topography

The difference between erosion and weathering Erosion is the wearing away of rocks, and other deposits 0on the earth’s surface by the action of water, ice, wind, etc. Weathering is the mechanical and chemical breakdown of rocks by the action of rain, snow, cold, etc. erosion weathering

What is soil erosion? Soil erosion is when the soil is blown away by the wind or washed away by the rain. Some ways we can prevent soil erosion by planting more trees, avoiding deforestation, avoid soil, air pollutants in destruction of plant habitat, use mulch, and avoid felling of trees.

Study of Historic Hopi Buttes Area Hopi Buttes volcanic field is a monogenetic volcanic field located on the Colorado Plateau. Most of the activity occurred between 8.5 and 6 million years ago, with the most recent dated at 4.2 million years ago.

Erosion in the Southwest Build groynes, plant trees, build offshore breakwaters, and build artificial headlands.

Coastal erosion prevention Erosion is carving into Southwest Washington beaches. Erosion rates at Cape Shoalwater have averaged over 100 feet per year for a century. In recent decades, new erosion hot spots have developed.

Wind erosion prevention Wind erosion happens when the soil is left unprotected from the strong winds. The loss of topsoil lowers the quality of the soil. This makes it more expensive and harder to grow good crops. The blowing soil can also plug ditches, make driving more difficult, plug ventilation equipment and so on. Country and city people should both be concerned with wind erosion. Strong winds will always be around but we can do certain things that will protect the soil from blowing away.

Beach erosion prevention study California's coast, one of our most precious resources, is a naturally eroding shoreline. It is both economically and socially important to minimize the loss of the State's beaches and to preserve its coastal resources. When erosion threatens to damage valuable infrastructure, or there is not enough beach width to accommodate the recreational needs of the local population and the State's many visitors, beach erosion control projects at carefully selected places can halt the erosion.

Geological Hazards: landslides Landslides constitute a major geologic hazard because they are widespread, occur in all 50 states and U.S. territories, and cause $1- 2 billion in damages and more than 25 fatalities on average each year. Expansion of urban and recreational developments into hillside areas leads to more people that are threatened by landslides each year. Landslides commonly occur in connection with other major natural disasters such as earthquakes, volcanoes, wildfires, and floods.

Federal Emergency Management Agency landslides and mudflows Landslides occur when masses of rock, earth, or debris move down a slope. Debris flows, also known as mudslides, are a common type of fast-moving landslide that tends to flow in channels. mudflow landslide
