Document Summary
Hypothesis is a statement that proposes a possible explanation for a particular observed phenomenon. Null hypothesis a statement of no effect . Predictions what you expect to happen if your hypothesis is true. Study designs have good sample sizes, unbiased, are achievable, have some kind of comparison and is ethical. Accretion growing by sticking/ clumping together. Differentiation (low density materials move to outside while high density materials move to middle) Jovian (outer) plants huge, gaseous and icy, very low density, less rocky material compared to ice. Terrestrial (inner) planets small, rocky and metallic, high density, more rocky material compared to ice. 1 solid less dense than liquid ice is less hence that water hence ice floats. Fossil a remnant of a long dead organism, preserved in stone. Fossil records give info about history of past life. Chemical evidence can show that life was there (traces of organism poo) 4. 5 ga earth was hostile to life.
