Glaciers in Oregon and The Fertile Crescent: Fields and Rivers Essay

Glaciers in Oregon Glaciers are a big part of life in Oregon. Glaciers supply drinking water, they irrigate crops and they help generate hydroelectric power. They are also a tourist attraction in areas that have more mountains. Glaciers are a natural resource that are so rare that people all over the world are trying to get these â€Å"frozen streams.† People want the power of glaciers because they can provide drinking water and people living in the city of La Paz, Bolivia rely on the melting of the glaciers. Glaciers irrigate crops and thousands of years ago people in Russia and Asia knew that dark colors promoted melting. This is how they watered their crops during dry periods. Even though this method has been proven very costly, India has created artificial glaciers to provide people with more water. Scientists have been damming glacial meltwater to help generate hydroelectric power. Glaciers supply drinking water to the community and are running low because they are continuing to melt. Glaciers have drastically changed over time because on average, â€Å"glaciers worldwide have been losing mass since at least the 1970s†. The melting of glaciers has been contributing to the rise in sea level because the glaciers have been shrinking faster in the last decade. Three of the major glaciers in the us have shown an overall drop in mass since the 1950s and 1960s and an accelerated rate of decline in recent years. An ice cap covered Mt. Hood during the Ice Age, from about 1.8 million years ago to about 10,000 years ago. These ice caps covered the Oregon Cascades, a series of mountains in Oregon, with glaciers going down on the east and west sides of the range. These glaciers melted into smaller glaciers as the weather proceeded to get warmer... ...ollapsed, but the Nile continued to grow and Great Britain took control of the Nile in the 19th century. Around 60 years ago the Africans gained control of the Nile. Rivers and fields affected the people who lived in the Fertile Crescent throughout the years because of the fertile soil and water. Many people lived in the Fertile Crescent and prospered from the fertile soil by growing an abundance of crops. Once it was abandoned, the Fertile Crescent became cracked soil and vacant land.
