GEOL 1001 Study Guide - Midterm Guide: Magnetic Dip, Protoplanet, Bathymetry
Document Summary
Part 1: what is the big bang theory, elements come from the stars, basics of the planets in our solar system. Notes: universe contains all matter and energy, matter-takes up space, things you can feel. Weight- w=mg force due to gravity. Density- amount of mass in a given space d= mass volume: energy- ability to do work. Hydrogen fused to make helium: within 5 mins: all atomic nuclei formed, accumulation into patchy clouds nebulae . 26% helium: stellar nucleosynthesis (objective 2, 92 naturally occurring elements, stars are nuclear fusion reactors. Now can exert a gravitational force: suck in debris, grows to a protoplanet, becomes a planet, our solar system, formed 4. 57 ga (age of earth: sun contains 99. 8% of mass. Cleared its neighborhood of other objects/pulled all objects" matter into orbit: inner planets. Jupiter & saturn: giant planets, gas giants. Uranus & neptune: giant planets, ice giants.
