The Earth’s sustainability, going green, and limiting our carbon footprints is an ever-growing issue in the minds of most of the planet’s population today. We are all growing more aware of our depleting resources, as well as the role humans have played in their running out. Many are becoming more conscious of their carbon footprint, myself included, and are attempting to limit their impact on the Earth and its resources in an effort to undo the seemingly irreparable damage that has been done. Others, however, appear to not care, still believing that the Earth will never run Continue reading...

Solutions:

1(a) The liner reciprocating motion of the piston is converted into rotary motion of the
crank shaft by a connecting rod, which connects the piston rod to the crank. As can be seen above, because of the nature of the linkage, at the start the crank and the connecting rod remain in a straight line. As the piston moves downwards during the power stroke, point b starts to move clockwise. This is obvious because the piston coming down means the connecting rod has to accommodate the travel of the piston. Finally, when the piston reaches the extreme end, Continue reading...

I am a senior student at San Jose State University, and I am an economics major student at the university. I developed interest in economics very early in my career. I understand that to learn the effect of economics on the society, one has to learn the economics in depth. That is the main reason to choose the economics as my major. I am basically from China, but now I am US citizen. I used to work Continue reading...

The Pacific Northwest is the most volcanically active regions in the United States. It consists of several volcanic peaks which stretch all the way from Canada to northern California. Falling in this region is the southwester territory of Washington State, which has witnessed some of the most spectacular volcanic activities in recent times. Mount St. Helens, which erupted in 1980, is located in this region (Harris, 2005). The volcanic eruptions in this region result from plate tectonic movements.
The plate tectonic theory is based on the postulation that the Earth’s outer layer, lithosphere, is composed of several plates. Continue reading...

Ruddiman’s article “The Anthropogenic Greenhouse Era Began Thousands of Years Ago” is an intriguing take on the global climatic impact that humanity is believed to be capable of producing. The article begins by acknowledging that generally the Anthropocene is not considered to have started until 1800 AD at the beginning of the industrial age. However, Ruddiman asks the question, “Did human created emissions of methane and carbon dioxide result in an earlier start to the anthropogenic era and overall climate warming than current estimates dictate?”’ He approaches the solution through a detailed examination of scholarly articles and data Continue reading...

Mining refers to the extraction of valuable mineral resources from the earth’s crust. While some minerals are found at the earth’s surface, other minerals are found deeply below the earth’s surface. Irrespective of their location in the crust, the extraction of minerals is a complex process often fraught with danger. America’s mining industry has been supported by the increased demand for raw materials by other sectors of the economy. As the demand for mineral resources has increased, mining has become more complicated leading to accidents. Mine disasters refer to accidents that occur during mining activities Continue reading...

There are lots of environmental problems that the people living in this world encounter. These environmental problems are mostly governed and even made worse by the actions of the people to be able to survive and live their lives to the fullest. One of the most pressing environmental issues is the worsening global warming that further leads to climate change. To be able to understand how these environmental issues affect the lives of the people on Earth and how the activities of man leads to worsening environmental condition, the issue of Maryland Power Plants will be discussed.
There are Continue reading...

1) Physical Map showcases landforms like deserts, plains and mountains; Political Map shows state and national borders, as well as bodies of water and cities- The Rocky Mountains prevented trade, while rivers such as the Mississippi facilitated trade.
2) Maps and geography are important because they allow us to understand where we are in relation to other places, as well as understand the geographical context for the way peoples in other regions live.

The Grand Canyon is one of the most stunning natural wonders of the world. It is a collection of mighty rock formations carved roughly by the Colorado River millions of years ago. Geologists estimate that the majestic Grand Canyon is nearly 450 kilometers long (280 miles) and almost 2 kilometers deep, equivalent to one mile (Grolier’s Student Encyclopedia, 2004, p. 44). Its peaks and gorges vary in width (Wenk, 2010, p. 19-20). As the Colorado River cut deeply, it created huge dents called ‘gorges’ on the surface of the rocks, which eventually exposed the buried fossils of ancient Continue reading...

One of the natural phenomena that I wondered about was the formation of rainbows. Almost every time rain ends or there is a mist of vapor in the streets, I tend to see rainbows. So I asked myself, how do rainbows form, why is that rainbows are always semicircular in shape, and why are they always arranged in the order: red, orange, yellow, green, blue, indigo, and violet?
My limited knowledge in physics came in handy to answer these questions. Accordingly, for the first question, white light just like the light that comes from the sun is actually made Continue reading...
