Document Summary
Geology: the description and understanding of the composition, behavior, and history of the earth. Solar system starts in a nebula (remnant of a supernova) Heavy metals in solar system indicates that our solar system developed in a. The nebula develops angular momentum and organizes into a disk. Rocky and icy grains in the nebula formed into planets. Rocky grains --> condense closer to the sun to form the terrestrial planets. Icy grains --> condense farther from the sun to form the jovian planets. Uranus has a rotation perpendicular to its orbit about the sun. Age of the earth is determined from the age of asteroids that have impacted earth. Theory #1: co-accretion earth and moon developed at the same time. Development at the same time and same time would mean that the earth and the moon must have similar composition (they don"t). Theory #2: spin-off earth"s rotation was so fast that the moon got thrown off.
