question #6

Converging plate boundries are the plates that move together, these are in the form of trench and island arc systems. Diverging pull apart from each other, which creates mid oceanic ridges as magma from the mantle upwells through a crack in the oceanic crust and cools. In the case of earthqueakes these happen by transform or convergent type plate boundaries, which form the largest fault surfaces on earth, they will move past each other smoothly and aseismically only if there are no irregularities or asperities along the boundary that increase the frictional resistance. Three major types of valcanoes are shield valcano, stratovolcano, and cinder cones. Shield volcanoes are large with shallow-sloping sides. Stratovolcanoes are tall, conical volcano composed of many layers of hardened lava, tephra, and volcanic ash. Cinder cones are steep conical hill of volcanic fragments that accumulate around and downwind from a volcanic vent. The Ring of Fire is an area of frequent earthquakes and volcanic eruptions, it is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and plate movements. I'll use this information in the future because now I know about how the plates effect the earth. I never knew how much of an impact it had on the earth. Others might say that is doesn't matter, but it does because the reason the earth is like this today is because of the plates moving. Common good would support this because people can be informed about it.

question #3 final exam

Renewable energy means using natural factors such as wind or solar effectively. Nonrenewable energy means using natural factors like oil or and nuclear supplies that can not be used again. Energy is changed from one form to another, and can't created or destroyed (law of conservation of energy). From 1961 to 2001 the world consumption of nonrenewable resources has increased over 700 percent. Due to this the earth can't filter out the carbon emissions as fast so it is destroying the ozone layer. When it comes to renewable resources the united states wastes the most, using more than 29% of the world's annual output.
Based on public or common good, i know we need to find an alternate for fossil fuels or else the ozone layer will be gone. According to what i've heard that we have enough oil in Alaska to last for three years, so we can use that time to create an alternate fuel. arguement against it would be what happens if not enough renewable resources are made what will we use for gas?

activity 1

La Niña is cooler than a normal sea- surface temperature in the Pacific Ocean. the storm comes to land based through series easterly trade winds strengthen, cold upwelling from Peru and Ecuador intensifies. the temperatures in the midwest are cooler than normal. info provided by http://www.elnino.noaa.gov/lanina_new_faq.html

my topic relates to activity by when it hits it makes things cooler in the midwest than normal.

the activity was seeing the change in temperature of dirt, snow, and water. we started by heating the objects with a light and then we cooled them by turning off the light.
