The purpose of soil erosion is to show how the relationship between precipitation and soil along with how it can make water. It will identify the causes and effects, the process, and solutions of soil erosion. This will discuss what farmers and others need to be mindful of due to soil erosion of their lands and crops.
Soil erosion is identified as a “the wearing away of rocks and other deposits on the earth's surface by the action of water, ice, wind and the act of process of eroding or the state of being eroded.” (Dictionary.com, 2017) When soil erosion occurs it can cause damage due to decrease of topsoil and the inability to store water and nutrients for plants. Natural causes can damage the land and growth of crops from rain water

Plants help to check for the erosion considerably during floods or lots of rain. When a flow of water comes it washes soil away. However, deep rooted plants help the soil not get washed away by the water pressure. Therefore plants help slow down a soil erosion.
There are two different forms of a water erosion, soil movement and bank erosion. First soil movement is a sheet erosion, which is mass wasting, movement, and slope movement. Second form of water erosion is bank erosions. This is the wearing away of the banks of a stream or river. Some effects of the water erosion is due to the climate and the soil surface. Depending on the weather such as the wind, rain, snow, or if it’s sunny it can affect the erosion process. The soil surface effects the erosion because this is where cropping is done.
The process of the soil erosion is detachment, movement and deposition. Detachment is identified with the separation or disconnection of the soil. Through movement and deposition is changing location and deposing items. Soil also may be moved and detached by water, wind, and tillage. Soil forms from a thin layer of material covering the Earth’s surface. This is formed by the weathering of rocks, but mainly made up of mineral particles, organic minerals, air, water, and living organisms. They all come together slowly yet constantly to form

Agriculture can remove valuable topsoil, which is the most productive part of cropping. If this soil layer is no longer valuable this will result in higher production costs and less productive cropping lands. This elimination of topsoil causes rills and gullies which make agriculture impossible. Eroded soil, contains nutrients, can be deposited in grassed waterways, dams, or wetlands. Reef water quality has deteriorated over the past 150 years. When major floods occur this affects high, excessive levels of water from rivers which can damage land in time. Infrastructure is being aware of soil containing sodic. This is soil with a high percentage of sodium ions. Sodium ions are vulnerable to soil erosion which affects many infrastructure projects.
In conclusion, there are various factors to consider due to soil erosion. There is multiple causes of soil erosion due to vegetation, cropping of lands, along with precipitation that affects the ground due to natural weathering. Natural weathering includes rain, snow, sleet, and wind. There is several parts of the process of erosion that damages lands of crops. However, farmers and others can identify solutions to manage erosion to safeguard their crops. It is essential to cover crops, properly harvest lands, and continue to develop awareness of signs of soil
They act as a shield against wave damage throughout storms, protecting the land behind from salt water intrusion. This sand barrier allows the growth of more complex plant communities in areas protected from salt water inundation, sea spray and strong winds. Communities of plants that grow on beaches and dunes are known as dune vegetation.
Removing vegetation removes the root systems, which help hold soil in place. Running water can now more easily wash soil and rock away, increasing erosion.
Erosion is when the elements such as wind, water, and ice remove pieces of land. (“What is Coastal Erosion?”) Coastal Erosion takes place when destructive waves wear parts of the coast away. Four ways in which this takes place are corrasion/abrasion, hydraulic action, attrition, and corrosion/solution. (“Internet Geography”) Corrasion/abrasion is when materials are hurled at the base of cliffs through waves. Hydraulic action is when waves hit the base of a cliff and air is compacted, when the wave leaves air is rushed out and often this causes the material to break. Attrition is when the waves cause rocks and pebbles to smash into each other and eventually break into pieces. Finally, Corrosion/solution is when certain types of cliff erode from the result of acids in the sea. (“Internet Geography”) Coastal Erosion is the natural process of taking land away permanently from one place to put it somewhere else. (“What is Coastal Erosion?”) Eroding coastlines are an abundant and important topic because it can change people’s surroundings in a negative way. I would like to address the questions surrounding Coastal Erosion.
As a result of the beach popularity, the landscape at Kirra has been damaged primarily due to the increasing pollution and the higher demand placed upon the beach to increase development. 2.2 Impacts of Natural Features and Processes 2.2.1 Beach Erosion Erosion is the process of wearing away the surface of the Earth. It is commonly a result of impact from wind, water and human activity. Erosion can often be categorized into a range of processes, including hydraulic pressure, abrasion, attribution and corrosion. (See Appendix A).
Thinner soils that have fewer nutrients are more vulnerable to the effects of acid rain. Thicker soils are more affective at buffering acid rain. Over many years soils that aren’t the best at buffering out acid rain can become increasingly acidic. This leads to a decrease in the ability to support healthy plant life. Over time soils may become so acidic that aluminum dissolves and is carried by rain water into bodies of water. Aluminum that is dissolved is very toxic and harmful to all aquatic life.
There are many different ways that erosion is being caused. Some natural but most un-natural or man-made. The
They also help balance natural ecosystems, which allows more evenness of plant
What is soil? “Soil is a complex mixture of eroded rock, mineral nutrients, decaying organic matter, water, air, and billions of living organisms, most of them microscopic decomposers.” (Miller and Spoolman, 211). As stated, soil is made when a mixture of items such as eroded rock and mineral nutrients come together. Soil is used in a plethora of ways. Soil is where many of the nutrients plants need to grow comes from, soil purifies water, and even absorbs carbon dioxide from the atmosphere to be stored as carbon compounds (Miller and Spoolman, 211). Scientists study soil to develop a better understanding how this crucial factor in human’s survival functions and how to make sure humans don’t waste this precious resource (Miller and Spoolman, 211).
This model is designed as a guide to farmers, scientists and other workers relevant with the evaluation and control of soil erosion by water.
It’s funny how things that you used to do as a kid can change the course of people’s lives. Myself, when my parents told me and my brothers and sisters that we were going to the cabin meant a week of solid fun. My family has a cabin up on Camano Island, which is about 20 minutes north of Everett, right off of the I-5 interstate. My family would go up there during the summer with my cousins and grandma, and go swimming when the tide was in, build sandcastles when the tide was out, only to have them washed away when the tide came back in, build forts with the new driftwood that came in each year, explore the wrecked ship down the beach in one direction from our cabin, and scour the dunes that were north of our cabin. The dunes were the best part going to the cabin. We would always try to get there by walking along the wood that had been washed up and once we got there, we would race up the hills and jump down into the sand pits below. Another things that we all used to love doing, were to see who had carved messages into the sides of the dunes. There were all sorts of messages, love message from husband to wife, boyfriend to girlfriend. ‘I was here’ messages, and then there were simply names. That is what we always used to do. Every year, my two cousins, dad, three siblings and I would climb up into the dunes and carve our names into the wall using sticks. This was done over and over again for about 8-10 years. Over the last couple of years we did this we noticed that we could see a house at the top of the dunes. This was something that we never noticed before and when we asked my dad, he said that he never noticed it either. We thought nothing about it at the time, carved our names in the wall and went back to the cabin. Later on we heard from other people who lived up there that there was a big concern by the people who live in that house that all of the messages that people had carved along with the natural erosion of the hills has caused the hill side to be dangerously close to being pushed back far enough to where the house might fall down.
Coastal Erosion is a process at Muriwai that gradually wears away the rock particles of the earth's surface, transporting them to another location. There are many types of processes that cause erosion at Muriwai such as wave erosion, wind erosion and wave refraction.

Saline soil is also vulnerable to erosion due to the death of vegetation that held the soil together. Soil that is eroded can ‘pollute’ water too.
