MAN AND NATURE Human beings are the creations of nature. They drew everything needed for their very survival from nature. The air they breathe‚ the water they drink‚ the food they eat and thousands of articles they use daily-all come from nature. Yet‚ strangely enough‚ man keeps a hostile attitude towards nature. Conquest of nature is the expression which is often used to denote man’s activities like space exploration‚ taming the rivers‚ etc. which sums up man’s attitude towards nature. Our

findings of land was known in Greenland and in Norway but they didn’t find interest in it until about 10 years later. Although they didn’t land in North America‚ they were the first to make it out. After a few days the area turned more mountainous and glacial and departing to the east they found Greenland and Erik’s colony. One of Erik’s son got very interested in the story by Bjarni‚ especially that the frozen Greenland wood was hard to achieve‚ while Bjarni was counting about a forested country.

The Cuyahoga is known as an infant glacial river‚ this is because it is one of the youngest river created from the melting of the glaciers. It is estimated that the river is about 13‚000 year old. The story of the Cuyahoga is one with many lows and highs. The fires being the lows; new legislation and organizations formed to clean up and

have come and gone. As mountain ranges eroded‚ sediments many kilometres thick were laid down over vast areas. These sedimentary rocks were then subjected to folding‚ faulting and uplifting. Over time‚ the forces of weathering and erosion wore these down again. Erosion acts more quickly on softer rocks‚ forming valleys and bays. Harder rocks remain as mountains‚ hills and coastal

example‚ valleys‚ plateaus‚ plains‚ and hills. A valley is a hollow or surface of the earth bounded by hills or mountains‚ a natural trough in the earth’s surface‚ that slopes down to a stream‚ lake or the ocean‚ formed by water and/or ice erosion. Systems of valleys extend through plains‚ hills‚ and mountains. Rivers and streams flowing through valleys drain interior land regions to the ocean. At the bottom of many valleys is fertile soil‚ which makes excellent farmland. Most valleys on dry
