What would a diagram of molecules look when showing the phases of matter:
Gas______ , Solid ______, Liquid _______
Gas= spread out
Solid= tightly packed
Liquid= loose, begining to spread
Double the Points= Complete Answer
Why do we experience Tides at the Beach? Are the Tides stronger or weaker at night? Why?
Gravitational Pull of the Earth, Moon and Sun. Moons gravity pulls on the Earth's oceans as the Earth rotates. Moon closer to the Earth so greater pull.
