GEOL 1001 Chapter : GEOL
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: energy. 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. Within a few seconds, all the hydrogen atoms formed. Stars are nuclear fusion reactors: fuses light elements (hydrogen, helium, get heavier => iron (fe) Anything that did not become a star. Become planetismals => diameter is greater than 1 km and they can exert a gravitational force (suck in debris and smaller objects)
