Atmospheric Pressure

• Earths atmosphere is a thin layer that exerts force at a pressure of 100kPa at sea level
• What is the effect of altitude on Atmospheric pressure?

  As altitude increases the amount of air pressure decreases. This is due to their being less air particles in the air so the air is less dense.
• This graph is just representing what the slide previously showed about how altitude increases pressure decreases

  
• This is a demonstration on how there is less air particles as the altitude increases so the air is less dense therefore less atmospheric pressure
