apparent that the Fukishima Daiichi nuclear power plant meltdown had a disastrous effect on Japan as a whole. On March 11‚ 2011‚ a 9.0 magnitude earthquake hit the coast‚ just off of Japans borders‚ the earthquake its self‚ moved the earth off of its axis. The massive 5 minute long earthquake moved the earth’s tectonic plates‚ which then triggered a 15 meter high tsunami‚ less than an hour later. There was a 5.6 meter high defence wall‚ bordering the power plant‚ which sank about a meter during the

A1) Applying the indicators or hazard warning switch and check functioning of all indicators. (may need to switch ignition on‚ prompt not to start engine) TIP- Most cars will not need to have the ignition switched on to activate the hazard switch‚ so it should be simple to lean into the car‚ switch it on‚ walk around the car checking all 4 main indicators (there are also indicators

INTRODUCTION [SLIDE 2] Many chemical compounds found in the Earth’s atmosphere act as “greenhouse gases.” These gases allow sunlight to enter the atmosphere freely. When sunlight strikes the Earth’s surface‚ some of it is reflected back towards space as infrared radiation (heat). Greenhouse gases absorb this infrared radiation and trap the heat in the atmosphere. Over time‚ the amount of energy sent from the sun to the Earth’s surface should be about the same as the amount of energy radiated back

Nuclear Plants The question of whether the U.S. should have nuclear power plants is very controversial. There are two sides that one can take; however‚ both sides have their own share of problems. If you chose to not have nuclear plants‚ then eventually all natural resources will run out. The oil supply will run out relatively soon‚ and all other sources will run out too. The natural resources that we have now are still harmful to the earth however. The gas which we use for our cars pollutes

(AIU-Online‚ 2010) Even though the Natives outnumbered the Europeans‚ the dominance of the Europeans came after they brought infectious diseases that were unfamiliar to the natives that they had no immunities to which aided in their power as well as the resources or gunpowder‚ steel and crossbows. (AIU-Online‚ 2010) Because there are no real facts or evidence to why or how an entire group of people can disappear the possibilities seem endless. They could have been taken over by another

Fukushima Power Plant Nuclear power plants now account for 14% of the world’s electricity supply [1]. These power plants differ only by the fuel used from oil coal or gas power plants. The concept is otherwise the same. Large nuclei become unstable when struck with a neutron‚ his causes it to split apart and also produce neutrons which are fire out. This then causes a chain reaction and other nuclei are split up. This splitting of nuclei is called nuclear fission and it provides heat which heats

Merchant power plants differ from traditional rate-based power plants as to: 1) how they are financed and 2) where they sell the electricity they generate. A merchant power plant is funded by investors and sells electricity in the competitive wholesale power market. Since a merchant plant is not required to serve any specific retail consumers‚ consumers are not obligated to pay for the construction‚ operations or maintenance of the plant. A traditional rate-based power plant‚ on the other hand
