Document Summary
Builds and organizes knowledge in the form of testable explanations. Its empirical: derives knowledge from observation and experimentation. Falsification-ability to prove something wrong rather than proving ideas right.

Law-descriptive generalization about how some aspect of the natural world behaves under stated circumstances. Theory-well sustained explanation of an aspect of the natural world. Transitional forms-indirect evidence that evolution has occurred in the fossil record.

Terrestrial planets: mercury, venus, earth, mars, closer to the sun and smaller, metal core, surrounded by rock mantle and crust, secondary atmospheres formed by comet impact and volcanism.
