Assignment #1 SCI 110 Strayer University July 2011 Assignment #1 SCI 110 First discuss how energy can be converted from one form to another‚ giving specific example: There are two types of energy conversion‚ potential and kinetic. Potential energy can be converted to kinetic and vice versa (Tillery‚ Enger‚ & Ross‚ 2009‚ p. 63). Any form of energy can be converted to another form of energy. Energy conversion is evident in the following conversions-a light bulb converts electrical

Can alternative energy effectively replace with fossil fuels? ‘’Fossil fuels are coal‚ natural gas and petroleum.’’ (http://en.wikipedia.org/wiki/Fossil_fuel) They are all organic residues. People use this for their energy‚ fuel and heating requirements. But fossil fuels polluting environment so much and people started to think about using alternative energy for their environment’s healthy. ‘’These alternative energy resources are windy power‚ solar energy and geothermal energy.‘’ (http://en

Coal is a solid fuel formed over millions of years by the decay of land vegetation. Over time‚ successive layers become buried‚ compacted and heated‚ a process through which the vegetation is turned into coal. This means that it’s not possible to keep it going since we can’t wait around for a few million years. Coal was the first fossil fuel to be exploited on a large scale during the 19th century with the beginning of the Industrial Revolution. Production of these fossil fuels is expected to rise

Conserve and Preserve With today’s growing population‚ resource consumption is becoming a huge concern. It is important that humans realize what is best for both our present and future generation‚ and what is best for our planet. We must preserve certain areas from being destroyed to keep their natural beauty. We should also conserve resources‚ so they can continue to flourish‚ but also so we can continue to live our lives without depleting these resources. Every individual unit of the environment

everyone who drives should drive sensibly. Things such as speeding‚ braking‚ and rapid acceleration wastes gasoline. Each year‚ electricity generated by fossil fuels for a single home puts more CO2 (carbon dioxide) into the air than the average cars. (Source F) There are many ways to save energy‚ electricity‚ and your money. “Typically‚ if fossil fuel prices rise‚ consumers quickly use less and new supplies of ‘clean energy’ magically materialize.” (Source D) For this to actually happen in reality

will conserve any energy‚ yet we do advise every household to research the possibility of implementing natural energy resources to influence their home power supply. This will conserve the fossil fuels we are currently consuming at an alarming rate. Many little things can be done in an attempt to conserve energy in the home. It is knowing how to do these little energy conservation processes that many people do not know about‚ understand‚ or just don’t care. Another way relating to how we can

Whenever you save energy‚ you not only save money‚ you also reduce the demand for such fossil fuels as coal‚ oil‚ and natural gas. Less burning of fossil fuels also means lower emissions of carbon dioxide (CO2)‚ the primary contributor to global warming‚ and other pollutants. You do not have to do without to achieve these savings. There is now an energy efficient alternative for almost every kind of appliance or light fixture. That means that consumers have a real choice and the power to change

What are fossils? Fossils are the remains or marks of plants and animals that lived a very long time ago. They are usually found in rocks and stones. Fossils are important because they tell us a story about things that lived on the earth before us. What Things Become Fossils? Animals and plants become fossils. So do nests‚ eggs‚ footprints and even animal droppings! How are Fossils Made? Fossils are made from the hard parts of plants and animals‚ such as:-bark‚ seed cases‚ bones and

Fossils A fossil is the prehistoric remains of a plant or an animal. Fossils are usually are kept at their best when they are buried under many layers of sand and mud. Under the great pressure from the ground‚ the sand and the mud become sedimentary rock. The minerals combine forming a mould of the plant or animal under the ground. A fossil can be a trace fossil or a body fossil. A body fossil is what actual organic material from a creature or plant (like a bone). Trace fossils are signs of

Alternative fuels‚ also known as non- renewable sources‚ are substances that can be used as fuels‚ other than conventional fuels. Conventional fuels include: fossil fuels (petroleum (oil)‚ coal‚ propane‚ and natural gas)‚ and nuclear materials such as uranium. [ 1] The fuels we use now are finite‚ meaning they have a limited life expectancy. This along with the toxic waste they produce has made environmentalist and government officials alike take precautionary steps so that we do not
