The above diagram illustrates the volcanic activity on Venus, it indicates how activity this planet has been and still is. There is no evidence of plate tectonics on Venus along with no long linear volcano chains. There are also no clear subduction zones. Rifts are very common on Venus and they look much like the mid-ocean ridges on Earth. Volcanoes on Venus are much more regional and less organized then here on Earth. Volcanoes on Venus seem to have simple and fewer eruptive styles than the…

Narrowing Down A roofing Material? Why Choose Metal Have you ever looked around your neighborhood to see what kind of roofs are out there? While asphalt shingles are most likely dominating the neighborhood, you may see a few metal roofs out there. Metal can be a viable alternative to traditional shingles for the following reasons, so do not count it out so soon when narrowing down a roofing material. Life Expectancy The longevity of a roof will depend on several factors, such as the home’s…

Over time we’ve changed our minds about how the Earth came to be. Through the study of our planet and solar system we’ve widened our understanding of where we began. We went from thinking the Earth was the center of the universe to knowing for a fact that we are just a small spec in a huge ocean of planets and stars. After watching the documentary presented in class, the major theme I noticed was how over time and after years of research our ideas around how things worked and how they…

Heraclides Ponticus and Aristarchus of Samos: “We know that the Earth is (or is not) at rest because...” The two philosophers Heraclides Ponticus and Aristarchus of Samos lived back to back as Ponticus lived from 390 BC – 310 BC and Samos lived 310 BC – 230 BC. Samos was a radical believer in the heliocentric theory of the universe, while Ponticus believed in the geocentric model; however, he believed that the Earth rotated on its axis, but it is at rest otherwise. Should these men have ever…

First Solar, Inc. is a design and manufacturing company found in 1999 that produces photovoltaic modules, or solar panels, through the use of thin film semiconductors. The company however, has a much earlier history than scribed. In 1984, inventor and owner of Solar Cells, Inc Harold McMaster began manufacturing solar cells from silicon (energyandcapital, para 8). However, as silicon became more expensive, McMaster decided to switch to the use of a material called cadmium telluride. This…

holes to date in the cosmic background. This supermassive black hole contains 17 billions times the mass of the Sun, only slightly smaller than the most massive black hole ever found, which is 21 billion solar masses. For comparison, the black hole at the center of the Milky Way totals only 4 solar masses . This newly found black hole lies in the center of the galaxy NGC 1600, which lies 200 million light-years from Earth in the constellation Eridanus. Supermassive black holes likely form by…

Standalone Solar Systems - Best Source of Power Supply By monety rackson Jan 25, 2013 Despite energy being the dire need of everyone, there are some corners of the world that still lie shady because of the absence of energy. Fans, air conditioners, bulbs, one cannot think of a life without them. But these things are left meaningless in the absence of energy. Solar systems With time, solar systems have emerged as a solution to the power needs. Whether it is a place where energy does not reach…

To start off the exhibit is the Precambrian period. The Precambrian period lasted for 4 billion years. Scientists believe that this period where 90%of earth's history was discovered. Life first started evolving, and progresses and changed the planet. Scientists discovered the truth about organic compounds, the first prokaryotic cells and the first meteorites to hit the earth. Scientists believe that some of these meteorites gave rise to organic compounds, or life's building blocks. The Cambrian…

Stars are an appealing component of our universe. Because of our scientific advances, we know more about stars than ever before. They are born, they live, and then they die. How does this process work, though? The answer lies within thermodynamics. Thermodynamics has helped us understand how stars transfer energy and heat. Thermodynamics is a subject of physics that is concerned with heat and temperature. It is used to describe bodies of matter and their internal energy. Thermodynamics helps us…

‘While standing on a bridge on the morning of 3/20/66,... at 01:25, Radioman Third Class John R. Weitlich, saw something he had never seen before... I thought that I was only seeing some lights from the lighthouse.. then at that moment, all the power was cut out in the area, this was after i had noticed a huge, flash of light!.. it appeared to be that there was a big object about 300 to 500 feet off of the ground, this emitted an eerie white light that appeared to pulsate in its intensity. When…
