Erosion: Actions That Move The Earth

Mar 29, 2023 | General News, Scholars

Erosion is a process that happens when natural forces like wind and water wear away the Earth’s surface. Erosion can happen slowly over a long period of time, or it can happen quickly during a storm or other extreme weather event. It’s a natural process that helps shape the land around us, but it can also cause problems like landslides and flooding.

The Types of Erosion

Coastal Erosion

The waves and tides of the ocean can erode beaches, cliffs, and rock formations along the coast.  Imagine a beach where the waves crash against the shore; over time, the force of the waves can break down the rocks and sand and carry them away. 

River Erosion

When a river flows, it picks up tiny bits of soil, rocks, and other debris and carries it downstream. This process can create deep canyons, steep cliffs, meanders, and even waterfalls!

Wind Erosion

Wind can erode the surfaces of rocks and soil, and transport sand and dust across the landscape. This is particularly common in arid or desert regions.

Glacial Erosion

Glaciers are huge masses of ice formed from layers of snow and ice that build up over many years. Glaciers can carve out valleys and shape mountains through the movement of ice and rock. This is a slow process that can take thousands of years.

Soil Erosion

This occurs when soil is washed or blown away from its original location. It can be caused by heavy rain, wind, or human activities like farming or construction.

Is Erosion Bad?

Erosion is a natural process that happens constantly on our planet, and it can be both good and bad, depending on the situation.

On one hand, erosion can help create new landscapes, such as canyons, valleys, and beaches, and it can also help to redistribute nutrients and minerals in the soil. For example, when soil is eroded from one area and moved to another, it can enrich the soil in that area and support the growth of new plants and trees.

On the other hand, erosion can also cause problems like landslides, flooding, etc. When erosion is too rapid or severe, it can strip away the topsoil that plants need to grow, leading to many environmental problems.

Additionally, erosion caused by human activities; such as deforestation, overgrazing, and mining, can also damage the environment. These activities can make erosion worse, leading to soil loss, water pollution, and the destruction of habitats for plants and animals.

How Can Unwanted Erosion be Avoided?

Human activities such as deforestation, overgrazing, agriculture, construction, mining, and other activities could lead to pollution and climate change. There are many ways that you can help prevent unwanted erosion, such as:

Planting Trees and Plants

You can plant trees and other plants to help stabilise soil, prevent erosion, and help care for plants by watering them and removing weeds.

Avoiding Littering

Litter contribute to pollution and can harm the environment in many ways, including erosion. When litter such as plastic bags, bottles, and other debris accumulate on the ground, it can interfere with the natural movement of water across the land. Microplastics (small pieces of plastic less than 5 mm long) in soil can also create new water channels that cause erosion and dry out soil.  By avoiding littering and picking up trash when you see it, you can help keep the environment clean and healthy.

Stick to Hiking Trails

Make sure you stick to designated trails when out and about in nature. Most hiking trails will have set out paths to follow. When we stray from these paths we can damage the plants along the trails and cause more erosion.

Everyone can make a difference by making small changes in their daily routines. By working together and making small changes, we can affect big change!

Erosion FAQs

How can erosion benefit the environment?

Erosion can benefit the environment by creating new habitats for plants and animals, redistributing nutrients in the soil, and contributing to new landscapes like canyons, valleys, and beaches.

What are some ways that erosion can be harmful to the environment?

Erosion can harm the environment by causing soil degradation, loss of biodiversity, sedimentation of waterways, and releasing pollutants into the environment.

How long does erosion take?

Erosion can take a long time, sometimes thousands or millions of years, depending on the intensity of the forces causing it and the resistance of the rocks and soil being eroded.

What are some examples of erosion in everyday life?

Examples of erosion in everyday life include the wearing down of roads and sidewalks due to foot and vehicle traffic, and sand dunes on beaches due to wind and human activity.
