1. Introduction Industrial emissions are a major sources of air pollution, and thus responsible for numerous deleterious effects on a human health and environment caused by photochemical smog, acid rain, and resultant degradation of ecosystems and bio-diversity. Ontario’s SO2 emissions are predominantly around 65 percent from industrial sources including non-ferrous smelting. The major environmental concerns associated with smelting are “energy consumption, releases of sulphur dioxide and particulate

The Glaciers of Yosemite National Park One of nature's most powerful and influential forces is also one of nature's coldest and slowest processes. These great icy rivers are called glaciers and have formed some of the most beautiful scenery on this planet. These enormous frozen bodies of water are often thousands of feet wide and deep and many miles long. They cover millions of acres of land and drastically change the land into beautiful mountains with many amazing features. One of the areas

THREE EXAM QUESTIONS AND ANSWERS PETROLEUM GEOLOGY -MY FIRST QUESTION AND ANSWERS 5) Discuss the different types of traps and seals and the importance of “timing”. Give an example related to the Middle East. “Trap” can be defined as shield against oil and gas movement. In other words, the trap system had been set up before the migration of oil and/or gas to this location. After coming across the trap, oil and

Introduction. Over the past century there have been rapid and noticeable changes in environmental conditions on Earth. These changes can be traced in various geospheres: alterations of the gaseous composition of the atmosphere, major decreases in global ice volume (Cryosphere), in both: land- and water based glaciers with consequent rise of sea-level (Hydrosphere), increase in the frequency and severity of geohazards (Lithosphere) etc. Triggering mechanisms for those changes include both: natural

The Powder River Basin Located in the western United States, the Powder River Basin is currently the United States largest producer of coal, and the coal that is produced here is some of the cleanest coal that is used in coal burning power plants. By producing such large quantities of low sulfur, clean burning coal, the Powder River Basin is of great interest, and we will examine the conditions and factors that helped to form some of the largest and cleanest coal seams in the world, along with coal

The Evolution of Animals Eukaryotes come in two grades of organization: single-celled (protists) and multicellular (plants, animals, and fungi). The world today is full of complex multicellular plants and animals: how, why, and when did they evolve from protists? Proterozoic Protists A single-celled eukaryote or protist can carry chlorophyll (it can be an autotrophic, photosynthetic, "alga"), it can eat other organisms (it can be an organotrophic, "protozoan" "animal"), or it may do both

Commonly, religious discussion turns to the subject of origins. There are two reasons for this: firstly, there are those with a literal or semi-literal interpretation of the Bible (or other relevant holy book) who remain convinced that the world was created in the recent past looking more or less as it does today. Obviously, this issue must be resolved before the existence or nature of the deity can even begin to be discussed! Secondly, even those with the more common, nonliteral interpretation of

Institute of Geography and Statistics, the total area is 8,547,403 square kilometers7. It spans four time zones and shares a border with every country in South American except Chile and Ecuador.6 Brazil's geological formation is very old. Precambrian crystalline shields cover 36% of the territory, especially its central area. Almost half of Brazil averages less than 200 meters in elevation and the coastal zone is renowned for thousands of kilometers of tropical beaches. Brazil has 26 states
