What are the different states of water?

Answer 5

Evaporation, Transpiration, Sublimation, Condensation, and Precipitation.

Question 6

What is the Coriolis effect?

Answer 6

The Coriolis effect is the deflection of moving objects from a straight path due to Earth’s rotation.

Question 7

What drives deep currents?

Answer 7

The differences in water density.
