When force increases...

• pressure increases

• pressure decreases

• pressure stays the same

• pressure increases then decreases

When area increases...

• pressure increases

• pressure decreases

• pressure stays the same

• pressure increases then decreases

Any substance that can easily flows and therefore can easily change shape.

• Fluid

• Liquid

• Gas

• Solid

As elevation increases,

• pressure decreases.

• pressure increases.

• pressure stays the same.

As depth increases,

• pressure decreases.

• pressure increases.

• pressure stays the same.
