What will happen to air pressure as you climb up a mountain?

• stays same

• increase

• decrease

• none of above

A box on the floor has a weight of 120 N. The surface area the box takes up is 4m².

What is the pressure exerted by the box?

• 30 Pa

• 50 m²

•  50 Pa

• 0.02 Pa

Four glass tanks contain water.

In which tank is the pressure of the water on the base greatest?

• 
• 
• 
• 

Where would you find the largest pressure?

• At the bottom of the ocean

• At the top of Mt Everest

• Close to ground on the Scotch oval

• In a rockpool on the Great Barrier Reef

In what direction(s) does air exert pressure?

• everywhere

• no where

• there is no pressure

• downward

Air pressure is greatest when near Earth's surface because?

• The air molecules are farther apart.

• The air molecules are closer together.

• Air molecules collide.

• Air molecules are tightly packed.

Air pressure is greater _______.

• at the top of the mountain

• at the bottom of the mountain

• at the center of the mountain

Air pressure does not crush objects on earth

• because more air pushes down than up

• because gravity keeps air pressure away

• because air pressure pushes in all directions

• because the Earth has an opposing force of gravity

If density of air is high, pressure is:

• high

• low
