...Term Assignment Population Dishan Mariarasa (4655834) Concordia University Term Assignment The evolution of humans has both positively and negatively contributed to an ever so changing environment. Understanding and educating ourselves about these events has become relatively important. In the world scale there are some indicators that must be used to understand a country’s positions and the world environment. A few of these measures will be discussed below. The level of income, population, and ecological footprint are some of the key factors that influence how the environment and resources are used up. Each of these element are related in one form or the other. For example, If income level of a country is high then in most cases the territory has a low population level and high ecological footprint. This can be vice versa for any of these indicators. One or two of these elements have a stronger impact on the worlds environment then the others. In my view I feel that population can be a major player in environmental health and sustainability. Population is a stronger impact on the environment health and sustainability compared to income. Population has been factor threw out history, beginning with the exploration by countries like England. As the need for new resources became a necessity the world map has been revealed and the population growth has lead to discovering new land and resources. With the world discovered is there any more room for the growing population...

...Year 10 Geography Coursework at Newhaven and Seaford, East Sussex. “Sediment is transported along the coast in large amounts and this has consequences for humans.” “Sediment is transported along the coast in large amounts and this has consequences for humans.” Introduction “Sediment is transported along the coast in large amounts and this has consequences for humans.” For our GCSE field work we were given this hypothesis (stated above) to examine. The most appropriate places we visited to investigate this hypothesis was Newhaven and Seaford on the South East coast. They are suitable places to visit as they are relatively close to us in Crawley, West Sussex. These places are most at risk from coastal erosion and flooding as they are along the South East coast. A process which transports sediment along the coast is called long shore drift. It is the process by which sand and pebbles are moved along a beach by the movement of waves. As water rushes up the beach it forms the swash and as it returns down the beach, the backwash. The most common direction in which the waves move is determined by the direction from which the wind blows most often (prevailing wind). There is evidence that long shore drift is operating and we are going to prove it. At Seaford long shore drift is constantly occurring moving sediment from West to East. Seaford regularly has beach replenishment operations where material is moved from one side of the beach to the other. Diagram of long shore drift...

...Analyse the factors that cause differences in the hazards posed by volcanoes around the world (40mks) There are many volcanoes around the world, some of which are active and others are dormant. The factors which cause them to be active are varied and can cause a threat to the surrounding area, including the environment and economy as well as the social impacts on people. A volcanic hazard however can pose a bigger threat to these socio-economic factors as a result of the eruption. Firstly, the type of volcano will also depend on the type of eruption and where abouts it lies within the plate boundaries. A hot spot however does not lie on a plate boundary but causes a volcano due to the high pressures of heat flow. An example of this is in Hawaii, southwest of the United States. Kilauea is a shield volcano on the southern part of the island which erupts runny, non-viscous lava and tends to be large in size with a low profile. These eruptions are not very explosive but occur very regularly and due to it being located in Hawaii, it is a very developed country and therefore caused various hazards to the area. Another type of volcano is a stratovolcano, this is different to a shield volcano because it is tall with a steep profile and causes more explosive eruptions. For example the Pinatubo volcano is located in the Philippines between the Eurasian and Philippine Plate on a destructive plate boundary. The last biggest eruption of Pinatubo was in 1991 however it was in a less economically...

...In primary School, we would define the atmosphere as a“ blanket covering the Earth” but in general it is defined as a layer of gases that surrounds the earth , I like to define it as the source of life ,that is to say there would not be life without the atmosphere . The atmosphere insulates the Earth from extreme temperatures; it keeps heat inside the atmosphere and it also blocks the Earth from much of the Sun's incoming ultraviolet radiation (NASA 1999). The Earth’s atmosphere is divided into four different layers , namely , the Troposphere , Stratosphere , Mesosphere and the Thermosphere, In this essay , I am going to explain , with the aid of a diagram the layered structure of the atmosphere, the different temperatures that occur and also the different processes that take place in all the layers. layered structure of atmosphere As you can see in this picture above, this is how the layers are positioned in the atmosphere, it starts with the Troposphere which is the bottom layer and the one closest to the Earth ,it is the most important layer because all life takes place here, the important gases which are essential for living are found only here , it has a height of 12km, almost all weather occurs in this layer, the air is warmer at bottom of the troposphere and as you go up it gets cooler until eventually it reaches a point of dryness because altitude varies with latitude All the different layers have boundaries that separate them, in the troposphere it is called...

...Assessment 1 04. The highest levels of insolation are found in the areas where there is a lower amount of cloud cover because if there is a lower amount of cloud then less insolation is reflected back into space. The highest rate of insolation is over Egypt. Over oceans the level of insolation decreases with increasing latitude both north and south of the equator. This is because of the decreasing angle of incidence of the sun, and so lower amounts of insolation occur. Over land it’s a lot different. Areas on the equator have lower amounts of insolation than areas both north and south, despite the higher angle of incidence. This is due to higher levels of cloud cover in these areas which reflect higher amounts back into space. The rate of insolation given decreases more rapidly in the southern hemisphere compared to the northern hemisphere. This is because there is a much larger cloud cover in the southern hemisphere due to there being more sea on the surface that provides an increase in water vapour for clouds. 05. Thermosphere – temperatures rise rapidly with height, perhaps to reach 1500°C. This is due to an increasing proportion of atomic oxygen in the atmosphere. Which like ozone, absorbs incoming ultra-violet radiation. Mesosphere – temperatures fall rapidly as there is no water vapour, cloud, dust, or ozone to absorb incoming radiation. This layer experiences the atmospheres lowest temperatures (-90°C) and strongest winds (nearly 300km/hour). The mesopause, like...

...Describe the landforms produced by rejuvenation. Rejuvenation is the renewal of a rivers energy in response to a relative fall in base level. Base level is the same as current sea level and so a drop in base level can be caused by either eustatic sea level fall, isostatic rebound or tectonic activity. There are three types of rejuvenation that I have learned about. One of them being incised meanders. Incised meanders are meanders which are particularly well developed and occur when a river’s base level has fallen giving the river a large amount of vertical erosion power, allowing it to downcut. There are two types of incised meanders, entrenched meanders and ingrown meanders. entrenched meanders are symmetrical and form when the river downcuts particularly quickly. Due to the speed which the river downcuts, there is little opportunity for lateral erosion to occur giving them their symmetrical shape. Ingrown meanders are asymmetrical. They form when the river downcuts at a less rapid pace, giving the river opportunity to erode laterally as well as vertically. Another type of rejuvenation is river terraces. This is caused by a river eroding vertically into the former floodplain. If vertical erosion is rapid then paired terraces are formed either side of the channel. If vertical erosion is slower though, unpaired terraces form as the river is given opportunity to meander. River terraces are particularly useful for settlements as they provide flat areas above the present...

...Ebola and the impact of development Ebola is a disease of humans and other primates caused by ebolavirus. Symptoms start two days to three weeks after contracting the virus, with a fever, sore throat, muscle pain and headaches. Typically vomiting, diarrhoea and rash follow along with decreased function of the liver and kidney. Around this time, affected people may begin to bleed both internally and externally. The virus may be acquired upon contact with blood and other bodily fluids of an affected human or other animal. Spreading through the air has not been documented in the natural environment. Fruit bars are believed to be a carrier and may spread the virus without being affected. Once human infection occurs, the disease may spread between people. There are more than 1,300 people with Ebola in West Africa and is having a devastating impact on the economies of Guinea, Liberia and Sierra Leone. The impact has spread thousands of miles to African countries that have never recorded an Ebola death. Facts about Sierra Leone and the impact of Ebola: * The economy has deflated by 30% because of Ebola in Sierra Leone. * The agricultural sector is most impacted in terms of Ebola because the majority of people of Sierra Leone (66%) are farmers. * 12 out of 13 districts in Sierra Leone are now affected with Ebola. * Road blocks manned by police and military are preventing the movement of farmers and labourers as well as the supply of goods. * The president believes...

...Lee Ho Ting 3035049110 Essay 1: Compare and contrast the main characteristics of the urbanization process in the First and Third Worlds Introduction As a necessary step towards development, both the First world and Third world countries have been undertaking the process urbanization. Urbanization is referred to the process of the increase in the total population living in the urban areas through immigration to the areas and net increase in the urban population (Pacione, 2009). Although the processes of urbanization are similar among countries, there are still differences as the First world is defined as capitalist industrial market economies where the Third world is referred to states that failed to develop economically after independence (Pacione, 2009). The differences in the social and economic situations in the First and Third world as well as the different global environment have led to distinct characteristics in the urbanization process of countries. Understanding these characteristics is essential to the understanding the challenges faced by states in the process. Therefore this essay is going to discuss the similarities and differences between the urbanization processes starting from the eighteenth century up till now from the social and economic aspects in respect of the global environment. Similarities – Economic based urbanization The major similarity between the urbanization of the two different worlds is that economic development played a significant...
