To add to this these methods need vast amounts of energy for extraction, causing the high extraction cost and with this also pollute greatly as the oil is extracted and so raise CO2 and other GHG emissions before the fuel is even burnt. Some of the environmental cost in these areas would be evident. The Canadian Tar Sands, Arctic and the marine ecosystems in the Gulf of Mexico are rich in biodiversity and pristine areas of wildlife and any spills of oil in these areas could be disastrous. The Arctic tundra is very sensitive to human interference and the Canadian Tar Sands is home to thousands of species of animals and is one of the largest bird migration centres in the world, millions of birds use this areas every year and groundwater depletion is another major problem as groundwater needs to be pumped out during mining operations otherwise flooding will occur. Reducing ground water levels will have consequences on the wider ecosystem and it will affect wetlands.
With using the criteria`s of: scale, genius, effort, and significance; we will see what they were. The Maya`s remarkable achievements were: trade networks, calendars, and the number system; However their most remarkable achievement was building cities. Three good examples of the remarkable achievement by the ancient Maya were trade networks, number system, and the calendar. The trade network reached across Mesoamerica from southern Mexico to Honduras (Doc A). The Mayan`s carried many products on these routes including cocoa, basalt
McKenzie Langford 26 November 2012 Pd. 3- McCauley Comparing and Contrasting the Byzantine Empire and the Dar Al-Islam The Byzantine Empire and the Muslim World were both significant to Afroeurasia during the middle ages. Each had major effects on the surrounding areas, and continued to influence cultures around the world in the following years. The Byzantine Empire and the Muslim world shared similarities in their economics and cultural achievements; however, their religious views were both similar and different at the same time. In the Byzantine Empire, trade played a very important role in their economic system.
They started the smelting process at the bottom of the mountain as well as other things that had to be down to prepare the silver for economic use. One down side to doing all these processes on site increased risks that the slaves could be hurt and killed by. As expected the number of deaths increased over the next three centuries and mercury had a large role in that. For one process of the smelting mercury would be used to help contain the silver and limit it to expanding. With this process could only come injury and death since mercury is a toxic element to the human
To begin, it would only seem right to explain the background of Africa itself before going into the methods through which its development was affected by the geography of the region. The continent of African was one that has been said to have rain forests, but that statement has been countered numerous times. In addition, the region had seafaring trade with numerous other civilizations and deserts that both hindered, and benefited certain civilizations. The agricultural aspects and benefits of the region played a role in its geography, making it a key element in the scale of development of the region and impacting it immensely. The Nile River, in particular, was an aspect of agriculture whose impact on African societies would change the way we see it today.
GKE Task 1 Part A: The Andean civilization, the Incas, had three diverse regions within the borders of their control. This was a significant physical geographic factor that contributed to the development of the early society. The three diverse regions were the coast, the rainforest, and the mountain. Each area produced different resources for the civilization. The coast gave fish and fruit, while potatoes were farmed, metals were found, and wool from llamas was collected in the mountains and the rainforest provided wood and coca leaves.
From the beginning geography held a profound effect on the evolution of Mesotopamian civilization, as Mesotopamia was settled in a catastrophic area. Being positioned between two river valleys, the Tigris and Euphrates and surrounded by little environmental protection left much of Mesotopamia open to constant cultural invasions and attacks. In time Mesotopamia became home to a huge collection of many cultures. Although the older cultures customarily looked upon the newcomers as inferior, the new just as invariably contributed valuable innovations to the old. Despite separate cultures however, each civilization managed to reside, maintain, and contribute new ideas and developments along the way.
Guatemala’s fertile soil made agriculture very easy and successful for the Mayans so permanent settlements began to rise. One of these settlements was Kaminaljuyú that was built around 300 B.C.E. Kaminaljuyú was one of the most prominent settlements at that period of time. This settlement was used mostly as a ceremonial center, but it still influenced other settlements in the area. Thousands of workers worked on building the temples in this settlement.
What is acid rain? Acid rain is any form of precipitation with high levels of nitric or sulfuric acids. It can also come in the form of snow, fog, and tiny bits of dry material that settle to Earth. What effects does it have on plant material? It robs the soil of essential nutrients and releases aluminum in the soil, which makes it hard for trees to take up water.
sd10/29/11 4th Period Chemistry EC Acid rain is any kind of precipitation with higher levels than usual of nitric and sulfuric acid contained in them. The causes for acid rain can be both natural and man-made, but the effect of acid rain is harmful in many different aspects. Acid rain is caused by chemical reactions, chemicals are released into the air, and they mix with precipitation and come down as rain. This can goHow acid rain starts How acid rain starts on for days, and spread far. Some natural causes for these chemical reactions include erupting volcanoes and rotting vegetation.
