Introduction For two days, on the 14th and 15th of April, a field excursion to Hastings Point, New South Wales was conducted. At Hastings Point, topography, abiotic factors and organism distribution were measured and recorded, with the aim of drawing links between the abiotic factors of two ecosystems (rocky shore and sand dunes), the organisms which live in them, and the adaptations they have developed to cope with these conditions. Within these two ecosystems, multiple zones were identified and recorded, and this report also aims to identify the factors and organisms associated with each zone. Lastly, using data and observations from the past, predictions for the future of the rock pool ecosystem were made.
3.1 1. Minerals have a few distinguishing characteristics that differ them from other materials. One of the biggest characteristic that minerals poses is they are naturally occurring, inorganic element or compound. Another is the hardness of the mineral. Minerals also have the characteristics of very different cleavage shapes.
Lake Huron on the other hand, has less dunes than Lake Michigan due to the fact that the western winds blow the sand back into the lake, making for a sandy bottom. Lake Superior has the only sand dunes on the Keweenaw Peninsula, which were blown in after the glacial departure. Glaciers may have played a large role in the shaping of Michigan but they were not the only foundation. There are actually three different groups of factors that cause erosion: terrestrial forces, aquatic forces and human activities. There are a handful of aquatic forces that have been a part of the shaping of
Rivers change the shape of the earth by eroding away sediments of the earth's surface. There are four different types of erosion created by rivers: hydraulic action, abrasion, attrition and solution. Hydraulic action is when the river bank is weakened by the velocity of the river, which allows air to enter small breaks in the river bank, and the bank slowly erodes away. Abrasion is when the bed and bank of the river is worn away by rocks carried by the river. Attrition is when rocks in the river forcefully hit each other and create smaller sediments.
In my hometown of Waterdown Ontario, there is rarely a minute when the main downtown area is not buzzing with people. In my opinion, the downtown area of Waterdown is alive and lively. Whether people are shopping in one of the variety of stores, grabbing a bite to eat at one of the numerous restaurants or cafés or just driving through, downtown is easily the focal point of town and continues to increase in chaos as Waterdown continues to grow and suburbanize. In Waterdown, the downtown core is where almost every shop and store is located. If you want to do anything from buy groceries to take a pottery class, you do so downtown.
The great falls mill ruin, on April 10th 1869, the great falls mill was located in Rockingham, along the railroads lines from Wilmington. The mill had been burned by Union general William Sherman 's troops in March 1865 near the end of the Civil War. The mill engaged in the manufacturing process, carding and spinning to dyeing and weaving. When it closed in 1930, the building included a five floors, a dye house, 6 warehouses, 2 office buildings, 42 spinning frames, and 205 looms. The mill burned in 1972, but much of the ruins
They saved thousands of acres of land from erosion. They kept farmland from ruining and land from fires and diseases. They decreased soil erosion by laying some topsoil to prevent landslides and mudslides. Another way to decrease soil erosion
Now we can see that the more land the farmers use with heavy mechanisms like tractors, the more soil and dirt is exposed. With the grass gone and dirt open, wind and dust will carry it up in the air and collect more and more when time goes
The Dust Bowl was a terrible era for America and took an extended time for recovery. It was a series of dust storms happening from 1932 to 1938 (Jones 1). Also known as the dirty thirties, the Dust Bowl was not the best time to be a farmer considering fifty million acres of farm land was destroyed ("Dust Bowl" 1). "The cause of the Dust Bowl was a mixture of natural drought and poor farming practices" (Trimarchi 1). Even though the Dust Bowl was an important part of American history, it caused much devastation and damage to the environment, people, and the economy.
The Dust Bowl stole the lives of many. It impacted thousands of farmers, children, adults, and land. The Dust Bowl was a time of suffering and challenges. The main challenge, was just staying alive. This is how it got its famous name “black blizzard” since it looked like a large black cloud.
The dust bowl was the most tragic event for farmers and the rest of the United States. The Dust Bowl negatively affected people in an economic way. The dust bowl made food way overpriced and rare to find fresh crops, and the great depression made the land really cheap. The dust bowl ruined people’s crops and land with the dust bowl big winds and it there was really bad weather in the dust bowl there was flying dust everywhere.
President Franklin D. Roosevelt once stated, “The nation that destroys its soil destroys itself.” President Roosevelt said this quote during one of America’s greatest hardships, The Dust Bowl, and this quote explains how important agriculture is to the nation’s economy. The Dust Bowl started in 1930 and ended in 1939. These dust storms raged across the Midwest, mainly Arkansas Missouri, Nebraska, Louisiana, Tennessee, Oklahoma, Texas, Colorado, and Kentucky. The Dust Bowl had detrimental effects on the United States of America, the main aspects of The Dust Bowl include the economic factors, agricultural factors, Black Sunday, the impact on rural families, and the resolutions that helped fix the problem.
4. Habitat alteration: Removal and reduction of natural habitat by flooding, soil erosion and water
When it rains, the water will flow from the hills to the lower area and then stagnant. Eventually the water will increase and flash floods will occur. 2.8.3 River Erosion River
Nowadays, environmental degradation has become an important issue. This is because environmental degradation is one of the largest threats that is being looked at in the world today. This is because of the depletion of important resources such as air, water, and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution. To limit the impact of these situations, it is important to know the possible side-effects of environmental degradation. Therefore, there are several causes and negative effects of environmental degradation provided in this essay with some recommendations to prevent it.
