Factors affecting the rate of coastal erosion Rock types - Soft rocks like clay or mud‚ erode faster than hard rocks like granite. This is because hard rocks are more resistant to erosion. This means that the hard rock is left sticking out into the sea as a headland. The headland is now vulnerable to the force of destructive waves but shelters the bays close by from further erosion. Wave type - Destructive waves cause more erosion than constructive waves. This is because backwash is more powerful

landforms of coastal erosion. (25 marker) Most of our landforms on the coastline are formed because of coastal erosion. But firstly it is essential to understand what coastal erosions are. Coastal erosion involves the breaking down and removal of material along a coastline by the movement of wind & water. They are sorted in two categories‚ Marine processes and Sub aerial processes. A few methods of erosion are; Abrasion‚ hydraulic action‚ Attrition and so on. These erosions leads to the formation

wash over your feet is an example of wave erosion. Waves cause a type of erosion. This type of erosion is most often seen at the coast or along the edges of rivers and waterways. The velocity of waves are affected by slope‚ discharge‚ and shape of the channel of the waterway. Erosion is found on all coastlines in the world. The effect of wave erosion can last up to millions of years or as little as a year. The Grand Canyon is an example of wave erosion and it took over five million years to form

Ways to Prevent Soil Erosion Soil Erosion Although many areas on earth can sustain plant growth‚ only about eight percent of the earth’s surface is covered with good topsoil. While it takes nature hundreds of years to make a few centimeters of topsoil‚ erosion can easily remove it. Without topsoil‚ people cannot raise crops for food.People know that without good soil they cannot raise agricultural crops. They also know from experience that wind and water can easily remove topsoil. Because of

Erosion caused by waves can be as subtle as the gentle wave constantly hitting the shoreline‚ or it can be a violent interaction between lake Michigan or inland lakes and the earth around them during ever during severe storms. In Michigan‚ there are primarily two types of material found on the shoreline. Bedrock‚ which is the harder of the two‚ known a consolidated substance and the effects of the water cause less erosion. Then there are the items like sand

The section chosen for this investigation was the Urangan beach‚ adjacent to Churchill Street. Its main issue it faces is beach erosion. Erosion is caused by the slow or gradual wearing away of sand‚ and is especially common during storms‚ high tide and rough weather. 2.0 Methodology Primary data was gathered in the form of images taken at the beach and guest speakers (Acworth

How to Prevent Soil Erosion TERRACING Terrace farming is a farming method that makes use of a hill to create a multiplatform farm. There are severals steps known as andenes which are built into the side of a hill. The idea behind it is that any rain that falls and builds up on the andenes will overflow into another andene below‚ making the most out of the nutrients it provides. CROP ROTATION The successive planting of different crops on the same land to improve soil fertility and help
