Examples of Gravity separation - Answers.com

if you had a pan of gold and dirt you would swish the pan around and wait for the gold to sink to the bottom because it is heavier. AND THAT IS GRAVITY SEPERATION. Also gravity is like when you throw a ball in the air and it alway's comes back down. These are Gisselle's a.k.a ( Dont leave me Alone ) example's of gravity.
