GEOL 1001 Chapter Notes - Chapter 1: Oceanic Crust, Peridotite, Basalt
Document Summary
Geologic processes phenomena and materials play a role in your everyday life (ex: sinkholes, oil production, earthquakes) Contains all matter and energy: matter. Anything that takes up space; things you can touch or feel. Mass is simply defined as the amount of matter. Weight is equal to mass x gravity (force due to gravity) Density s the amount of mass in a given space; d = mass/volume. Ability to do work (heat, light, magnetism, gravity) All energy and matter is packed into one point. Apparently occurred 13. 7 billion years ago (ga = billion years ago, ma = million years ago) Within a few seconds, all the hydrogen atoms formed. Within 3 minutes, the temperature is less than 1 billion degrees, diameter of the universe is 53 million km, and hydrogen atoms begin fusing to form helium. Stars are nuclear fusion reactors: fuses light elements (hydrogen, helium, get heavier => iron (fe) heavier elements => all goes back into space.
