An Intro To O-Chem
Scientists love to name things, classify them, so that there can be a greater order of knowledge. There are many examples of this. One such is in the field of chemistry. Each different type of atom has a different name to it. If there is one proton and one electron it is hydrodgen. If it has two protons, two electrons and two neutrons, it is helium. This goes on and on for each element. When you put several atom together you get a molecule. These are also named. Water has two hydrogen atoms and one oxygen atom. It is called dihydrogen monoxide. Di- meaning two, mono- meaning one and an -ide is placed at the end to classify it as a compound. Organic chemistry is the same way. One carbon with four hydrogens around it is methane. Two carbons with hydrogens surrounding it is ethane. Three carbons - propane, and four carbons - butane, etc. If you have a double bond in the chain, the ending of -ane goes to -ene. If there is a triple bond, the ending goes to -yne. Chains of carbons that come of the longest chain are also names. This is all done to keep science in an order of understanding.

Crystal Clear

An important tool for geologists out in the field is a hand lens. It is like a little magnifying glass that help geologists look at what crystals or minerals are in the rock that are not as visible with the naked eye. Most have power or magnification 10 times greater than normal vision. You can get some that are 15 or 20 times, and some even greater, but you start loosing depth very quickly and you'll need to look at a flat surface. Gemologists will also use a hand lens before, during, and after cuting a gem to inspect it.

Divergent Boundaries

Another type of plate boundary is a divergent plate boundary. Divergence occurs when extention takes place. You can remeber that divergence sound like divide. At theses boundaries a ridge will occur. It may look like there is mountain build but that happens with compression. As the plates split, the crack is filled in with underlying magma, which solidifies when it comes in contact with the cold ocean water, making new oceanic crust. This process continues and the older crust proceeds away from the ridge. As it gets older and cools down, it becomes more dense and sinks even lower into the Earth. These boundaries can also occur on land as well as under the ocean. Part of the mid-Atlantic ridge goes through part of Iceland. Another rift valley that is occuring is in the eastern part of Africa. As that rift valley splits it will eventually sink below sea level and be split off from the rest of Africa.

If the Earth did not experience plate tectonic, the land would never replenish itself. The land would evenually be all weathered away and eroded to to the oceans and there would be no land to live on.

Abide With Me, Tis Evenin' Tide

Some times the ocean itself seems alive. Why are there tides and what causes them. It all starts out with gravity. Gravity is not a very strong force, compared to electomagnetic forces, or the strong forces that hold quarks together, but it is a long force. It's amazing how far a field of gravity will reach. Such is the case with the tides. Gravitational forces, pricipally from the moon, and from the sun will pull the ocean closer too it which will pull the water in or out to sea according to the possition of the sun and moon. There are several classifications of tides. A Spring tide is when the tide is higher than average. A Neap tide is lower than average. Tides can also be classified as diurnal or semidiurnal, meaning they occur once or twice a day.

Holy Hurricane!

Another terror that comes from the oceans are hurricanes, cyclones, and typhoons. Lets not forget the damage done to our south eastern United States after hurricane season. I will not throw in any opions about New Orleans due to the possible sensitivity of any readers, however, as a geologist, my professional opinion would have been to NOT build the city on unconsolidated sediment. Or in other words: To have not built the city on a delta of sand which is sinking several inches a year. Building below sealevel on the coast is not wise for any geological surveyor. Ever notice that we mostly have hurricanes up the east coast and not the west coast? Well, it is possible but it is more common for them to form in warm tropical regions and follow the ocean currents northward near the coast.

What are the differences between a hurricane, cyclone and typhoon? Hurricanes form in the Atlantic Ocean, cyclones form in the Indian Ocean, and typhoons form in the Pacific ocean.

Tsunami: No Joking Matter

The think I love the most about geological hazards is how much power mother earth has. It could totally wipe us out. I previously spoke about earthquakes and the mass destruction they can do. The most powerful type of earthquake is at a subduction zone. That is when one tectonic plate collides with another and one plate is subducted under the other. The huge amount of friction gives greater strenght to deformation and a very nasty break when it slips. The highest recorded earthquake at a subduction zone (and anywhere on the earth) was classified as a 9.2 on the moment magnitude scale. That scale is a logorithmic function where as an earthquake classified as a 2 would be 10 times more powerful than one classified as a 1. So a 9.2 is over a billion times more powerful than a 1. Another danger of a subduction zone slipping is it will create tsunamis. When the ocean suddenly goes far out to sea, head for high hills because a tsunami is about to hit! If that makes you nervous, maybe you should move inland.

The tsunami that recently occured in Sumatra released so much energy when it slipped, it would be similar to over 10,000 bombs that landed on Hiroshima.

Earth Science Country

Hi, my name is Darwin and I'm a Earth Science Major. I'm working on an emphasis in secondary education. I'm currently attending UVSC right now and will graduate in the Spring of 2007. I am also a student of all sciences. I especially love astronomy. I've done some research with some of my professors the past couple years. I first worked on a report for the state department on Utah Lake. My subject was mineral resources and hydrocarbon potention. I also have done some research in the Santaquin metamorphic complex. We studied fractures and mineralization in fractures to understand stresses in the area, time of deformation, and see if there is any relation to the Wasatch Fault. This blog will contain many topics related to Earth science and similar topics.
Gee Wiz Collection:
The Wasatch Fault extends from Brigham City, UT to Levan, UT and can create and earthquake as large as 7.5 on the moment magnitude scale. As scary as that may sound, earthquakes are usually dormante for very long periods of time, and the area is a beautiful place to live. Utah too much of a desert for you? Then I would check out a home along the coast.
