Wind Vs. Dirt By Birdbrain Science

In this Geography GCSE controlled assessment project, I will be focusing on rivers and I have chosen a hypothesis to prove that erosion is making an impact on the Loughton Brook Rivers. My hypothesis is, “The river Loughton brook becomes wider and deeper due to erosion as it moves downstream”. I will be investigating if erosion takes place downstream in the river. I will investigate if hydraulic action has an impact. I will study about vertical erosion, lateral erosion, Cross profile and hydraulic action.

By the late nineteen-forties, when Rabalais was in his teens, the volume approached one-third. Before long, it would take all of the Mississippi, and itself become the master stream. Rabalais said,” They used to teach us in high school that one day there was going to be structures up there to control the flow of that water, but I never dreamed I was going to be on one. Somebody way back yonder which is dead to be gone now visualized it. We had some pretty sharp teachers.”

As stated in the last paragraph air pressure is made up of air molecules. But wind is made up almost completely different. Wind is the flow of air or other gases that make up the atmosphere. Wind is so strong that it can cause to make differrent landscapes or cause a tornado also known as a cycone. There are global winds, such as the wind belts which are between the atmospheric circulation cells. There winds which typically include certain type of cells in the air that are called jet streams. Gusts are short-lived increases in the strength of the

Erosion is a process where natural forces like water, wind, ice, and gravity wear away rocks and soil. Erosion occurs at the Earth’s surface, and has no effect on the Earth’s mantle and core. Water erosion is the removal of soil particles by heavy rainfall or running water. “While the causes of erosion by water are generally natural, water erosion is usually caused by rainfall and runoff on a slope” (GEI Works Erosion Pollution). “The process of water erosion usually occurs on stream and river banks, sea shores and seaside cliffs” (Reference.com).

The chemical characteristics observed and documented were pH, temperature, phosphate, nitrate, turbidity, and dissolved oxygen. Each of these chemical levels were documented and found differently. Most were found using a kit or a device. The numbers found, would tell us how polluted the stream was and how much nutrients were in the water. Each chemical has a scale for telling what a good level is and what a bad level is. If an excess amount of nutrients was found in the water, algae could be formed. When algae is formed it blocks sunlight from shining into the water, which creates dead zones. This is called eutrophication. A dead zone is an area where there is no life. This can cause major problems like population issues and more. If the algae continues to grow in the river, the whole body of water can die out, and people as well as other organisms are very dependent on the Susquehanna. While on the river though, there was an absence of algae, so sunlight is able to get through the water, which is very good.

At Nudgee Beach, erosion was found to have occurred on the edges of the mangrove forest and along the mudflat shorelines. Erosion is typically influenced by natural factors and occurs when pieces of weathered rock or soil are moved – typically by wind and water – from one place to another. Shorelines with lots of sediment and sand are more inclined to be effected by erosional progression. Erosion may also be provoked and accelerated by human interference. For example, if the decision to clear trees and plants from an area is made, erosion is likely to occur as the root systems of plants work to hold the soil in place. If these root systems are removed and erosion does occur, environmental conditions – such as; landslides and flooding – are more likely to take place. Erosion may also cause other plants to tip over, have their underground roots exposed and damaged and contribute to the pollution of local waters; as a result of mud and soil runoff [26]. Erosion at Nudgee Beach was likely to have been influenced by natural factors; however, the development and extension of the Kedron Brook golfing course may contribute to the acceleration of erosional processes and further damage the mangrove

Any rainfall increases fluvial erosion. When rain does fall, this creates ephemeral streams causing water erosion due to fast forces of water. Flash floods are possible as well creating even more erosion.

Even a small thing like dust can affect an entire country or continent, especially if there are tons of it. The 1930s, better known as “the dirty thirties,” was a hard time for many people because of the Great American Dust Bowl. The Great American Dust Bowl was one of the most catastrophic events in the world. Even though the Dust Bowl lasted four years, it felt like it could have lasted for more than a decade. Drought was caused by the “Prolonged misuse of grasslands in parts of Kansas, Colorado, New Mexico, Texas, and Oklahoma [which] led to one of the greatest environmental disasters in American History” (Baughman 2).

Natural Disasters have always been a major part of history. Disasters have helped shape history and expand mankind’s knowledge of atmospheric sciences. The influence of these disasters also can’t be ignored. One such disaster that left its mark on history is the Dust Bowl. The Dust Bowl was a period in the 30s in which severe dust storms swept across Southern plains of the United States (Dust Bowl). The Dust Bowl got its name when it first appeared in a newspaper article on April 15, 1935 (Shum). The Dust Bowl occurred due to widespread drought in the region and severe erosion (Long 1). Drought and violent winds caused widespread crop failure and the discouraged farmers did not practice proper erosion prevention measures (Long 1). Consequently,

The Ellicott City flood was destructive because it was on a high gradient stream. The high gradient stream made it flood faster, and had low stream discharge. Discharge is cross section of stream channel. It was also capable of moving large particles, which is an example of deposition and erosion. In the experiment, the ‘Main Street Ellicott City’ stream was more affected than the Meandering Stream. The Main Street Ellicott City stream was flooded faster, and more houses and cars were destroyed compared to the Meandering

In 1970, Robert Smithson created the “Spiral Jetty” with dump trucks, front-loaders, and a tractor to move the basalt stones and sand. The “Spiral Jetty” is located near the Great Salt Lake of Utah. Smithson created this piece so that the land and the water could meet. This artwork is supposed to change over time in response to the environment. Robert Smithson represents the idea of entropy in the  “Spiral Jetty.” Therefore, this landscape looks different than whenever it was first established. The “Spiral Jetty” is located at a terminal basin, which is a freshwater place with no outlet. Whenever it is done flowing it will evaporate. So the water is dense with minerals causing the high amount of basalt and sand. For this reason, not many plants

EOur Changing World Erosion changes the landscape of the earth. Erosion occurs in many different ways,through water,wind,and glacial rocks. Although,erosion can change the landscape of the earth,it has created many awesome landmarks. Erosion changes the landscape of the earth on a daily basis,Arches National Park was created by wind and water,The Grand Canyon was created by water. Yosemite National Park was made by glacial rocks,to name a few of the coolest landmarks.

Glaciers are one of the most fundamental phenomenon on the planet, and much of their purpose and impact on earth has been well documented and published. Ice sheets, Ice Caps and Glaciers trap nearly 90% of the world's fresh water, and are replenished by snowfall each year. Their existence on this planet dates back 650,000,000 years and yet they are always moving, always shifting and always melting. Before, human existence and even during the brief era of humans, ice dominated all of the earth's landmass and have regulated, created and altered many of the landscapes around the world.

The river also suggested a breeze, there were ripples that flowed southeast. There were many different shades of blue in the lake and river. The lake had a darker shade of light blue surrounded by a dark blue then lined with black. The lake appeared to have a light shining either on top or the bottom of it, which allowed you to see the grass growing under it. The river had a lighter shade of light blue with white lines to show the ripples but it was surrounded with the same colors as the lake. You did not see any grass growing under the river because there was no light shining on the river.
