What determines the pressure at a given point under the water surface?

 

[bigboss]

depth

 

[Doc Al]

depth

Exactly! Pressure depends on the depth beneath the surface. Use that to revise your answer.

 

[bigboss]

so it would be the bottom of the brick, because it has the most depth, thus the most pressure

 

[Doc Al]

so it would be the bottom of the brick, because it has the most depth, thus the most pressure

Correct.
