Space Geology

Imagine that you have a cup full of the average composition of the Solar System. You take it to the Solar Furnace in Spain and heat it unt mulberry sale il everything turns into a vapor. Under carefully controlled conditions you allow the vapor to mulberry sale begin to cool down and watch what happens. Some elements will begin to “precipitate” from the vapor at much higher temperatures than others. For example, Calcium (Ca) and Magnesium (Mg) are very refractory and leave the vapor state at temperatures greater than 4000 degrees kelvin. Others, such as Hydrogen and Helium remain in the vapor until absolute zero kelvin is approached. Elements begin to condense as a function of decreasing tempera mulberry sale ture.

As noted several times during the course, in the early history of the solar system meteorite bombardment of planetary surfaces (including Earth) was a very important process. A good introduction to impact structures is located at Impact structures

The Students for the Exploration and Development of Space (SEDS) at the University of Arizona have produced a wonderful WWW Home Page which I will refer you to rather than give you my notes for this chapter. As you read make sure you think about mulberry sale the differences between the inner and outer planets and the terresterial versus the “gas bags”.
