Structure of the Earth
Made up of layers; core (s), mantle (s), crust (s) and atmosphere (gas)
1 of 5
Miller-Urey Experiment
1952; H2O + NH3 + CH4 + H2 + a high voltage spark (simulating lightning in a storm) --> 11 different amino acids
2 of 5
Primordial Soup
Organic molecules (Carbon - C, Hydrogen - H2, Nitrogen - N2, Oxygen - O2) formed some kind of soup, and the amino acids in it combined to make proteins from which life began
3 of 5
States of Matter
(aq) = aqueous, (s) = solid, (l) - liquid, (g) = gas
4 of 5
Continental Drift
Wegener's theory 1915, that continents moved relatively to each other, appearing to drift across the ocean bed, was not accepted for many years
