Document Summary

Substantial event causing physical damage, injury or loss of life and/or drastic change to the environment. Elements: a chemical element consists of identical atoms. Atoms: protons (+) and neutrons in nucleus, electrons in orbit (-) Atomic mass #: the number of protons and neutrons. Isotopes: same element (same number of protons) different number of neutrons. Earth material most common elements in the earth, ocean, and atmosphere. What"s abundant in the atmosphere: nitrogen, oxygen, argon. Explain what density is and how it relates to stratification. The density of iron is higher than that of water. This is why iron is in the center of the planet and water is on the outside. Stratification: less dense materials float on top of denser materials, creating layers. Beyond these layers are where impacts come from. The outer core is liquid due to drop in temperature and pressure.
