Fill in the Blanks Air PressureOnline version This is meant to be a review of the air pressure within earth's atmosphere as well as a review of other characteristics. by Crystal Fullenkamp 1 pop lower more less cooler gravity breathe top harder oxygen different molecules dense decreases bottom top downward transfer mass weight matter temperature less altitudes Air is made of and therefore air has a . The force of pulls the air molecules . Air pressure is like a human pyramid because both have more matter at the and matter at the top . A human pyramid and air pressure also have pressure at the bottom and less at the as the of the matter pushes down . Your ears may as you change because the air pressure inside your head and outside your head is and has to balance out . It is to at the of a mountain because there is air pressure and therefore less to breathe . Air pressure is greater with altitude because there are more air pushing downward due to the force of gravity , making the air more . Air pressure the higher into the atmosphere you go . Lastly , molecules hold and heat . If there are less molecules at the top of a mountain , the at the top of the mountain will be much .
