Why is liquid water rare on Mars?

• It freezes immediately

• It evaporates quickly due to low pressure

• There is no sunlight

• The ground is too hot

What can the behavior of water on Mars teach us?

• About Mars’s pressure and temperature

• About Earth’s wildlife

• About distant galaxies

• About space travel

What is the relationship between pressure and boiling point of a liquid?

• As pressure increases, boiling point decreases
