GEO 100 - Earth Science - Sawah - 2018: Start Here

Geology is the science that deals with the earth's physical structure and substance, its history, and the processes that act on it.


 

GEO:100 Earth Science -  This introductory geoscience course emphasizes basic principles of astronomy, geology, oceanography and meteorology. Topics covered include the origin of the Universe, solar system and Earth, minerals and rocks, plate tectonics geologic time, prehistoric life and evolution, ocean structure and life, weather and climate change.

This Library Course Guide provides resources to generate curiosity and deepen understanding of course topics and to help students improve their information literacy and research skills.

Information literacy forms the basis for lifelong learning. It is common to all disciplines, to all learning environments, and to all levels of education. Being information literate enables learners to master content and extend their investigations, become more self-directed, and assume greater control over their own learning.  Information literacy is the set of integrated abilities encompassing the reflective discovery of information, the understanding of how information is produced and valued, and the use of information in creating new knowledge and participating ethically in communities of learning.” Source: ACRL Framework of Information Literacy.

Develop Your Research Skills

Research is never as linear as it looks on paper. As you become a practiced researcher, you will discover that the research process is never linear. Expect and welcome twists and turns; keep an open mind, and keep asking yourselves questions throughout the process. Use many different kinds of search tools and conduct many, different kinds of searches. Research can be fun, and it is a very valuable skill to learn. RESEARCH:

Humans are Destroying the Environment

" Top Ten Ways Man is Destroying the Environment" by Matt Schwarzfeld

Even the smallest human actions initiate environmental change. Misguided construction, irrigation and mining can deface the natural landscape and disrupt important ecological processes. Aggressive fishing and hunting can deplete entire stocks of species. Human migration can introduce alien competitors to native food chains. Greed can lead to catastrophic accidents and laziness to environmentally destructive practices.

So what are some of the worst offenders?

Global Warming

Global warming is caused by the greenhouse effect, in which certain gases trap heat from the sun in the atmosphere. Global warming could lead to natural disasters, large-scale food and water shortages and devastating outcomes for wildlife. According to the Intergovernmental Panel on Climate Change, the sea level could rise between 7 and 23 inches (17.8 and 58.4 centimeters) by the end of the century.

 Deforestation

The United Nations estimates that more than 32 million acres (12,949,941 hectares) of forest are lost each year, including 14.8 million acres (5,989,348 hectares) of primary forest -- lands not occupied or affected by human beings [source: FAO]. Seventy percent of the planet's land animals and plants live in forests, and the loss of their homes threatens the existence of an untold number of species [source: National Geographic]. 

Unsustainable Agriculture

One common trend emerges in all the ways mankind hurts the environment: We fail to plan for the future. Nowhere is this seen as much as in how we raise our food. According to the U.S. Environmental Protection Agency, current farming practices are responsible for 70 percent of the pollution in the nation's rivers and streams. Runoff of chemicals, contaminated soil and animal waste from farms has polluted more than 173,000 miles (278,417 kilometers) of waterways [source: Horrigan, et. al.]. Chemical fertilizers and pesticides increase nitrogen levels and decrease oxygen in the water supply. Even before the BP Oil Spill, the Gulf of Mexico suffered a "dead zone" the size of New Jersey from industrial run-off from factories and farms along the Mississippi River.

Coal Mining

The greatest risk to the environment presented by coal is climate change, but mining for the valuable resource endangers local ecosystems as well. Market realities create grave risks to mountains in coal - heavy regions, especially in the United States. Coal is a cheap source of energy - one megawatt of energy produced by coal costs $20 to $30, versus $45 to $60 for one megawatt of energy produced from natural gas [source: Moyers]. And one-quarter of the world's coal reserves are in the U.S.

Overfishing

According to the World Wildlife Federation, the global fishing fleet is 2.5 times larger than what our oceans can support. More than half of the world's fisheries are already gone, and one-quarter are "overexploited, depleted or recovering from collapse." Ninety percent of the ocean's large fish -- tuna, swordfish, marlin, cod, halibut, skate and flounder -- have been fished out of their natural habitats. It's estimated that unless something changes, stocks of these fish will disappear by 2048 [source: Worm, et. al.].

Dam Follies

Sometimes public works projects don't work out so well for the public. Meant to generate clean energy, dam projects in China have ravaged their surroundings by flooding cities and environmental waste sites and increasing the risk of natural disasters.The re-routed river has also greatly increased the risk of landslides along its banks, home to hundreds of thousands of people. It's estimated that another half-million people might be displaced by landslides along the Yangtze by the year 2020 [source: International Rivers]. And landslides choke rivers with silt, further depleting the ecosystem.

Scientists have recently linked dams to earthquakes. The Three Gorges reservoir is built atop two major fault lines, and hundreds of small tremors have occurred since it opened. Scientists have suggested that the catastrophic 2008 earthquake in Sichuan Province, which left 80,000 people dead, was exacerbated by water build-up at the Zipingpu Dam, less than half a mile from the earthquake's primary fault line. The phenomenon of dams causing earthquakes, known as reservoir-induced seismicity, is caused by water pressure building up underneath the reservoir, which in turn increases pressure in the rocks and acts to lubricate fault lines already under strain. An earthquake caused by Three Gorges Dam would present a humanitarian disaster of untold proportions.
