This celestial body is the main energy source that drives the water cycle.
What is the Sun?
This flow of water in Earth's oceans is caused by the unequal heating of Earth by the Sun.
What is ocean currents?
This type of heat transfer causes warm fluids to rise and cold fluids to sink.
What is convection?
This effect causes winds and currents to curve instead of traveling in straight lines.
What is the Coriolis Effect?
Rain, sleet, snow, and hail are all variations of this stage in the water cycle.
What is precipitation?
Earth's atmosphere and oceans near this imaginary line receive more heat from the Sun on average.
What is the equator?
In the process of convection, this temperature of air rises because it is less dense than the air around it.
What is warm air?
The Coriolis Effect occurs because Earth is doing this.
What is rotating around an axis?
Gravity powers these two processes in the water cycle.
What are precipitation and runoff?
These two factors create density differences in Earth's oceans.
What are temperature and salinity?
A lava lamp can be used to demonstrate this process that occurs in both Earth's atmosphere and oceans.
What is convection?
The Coriolis Effect causes Earth's winds to move in these two directions.
What are East and West?/Clockwise and Counterclockwise?
A puddle shrinking on a sunny day is an example of this water cycle process.
What is evaporation?
Ocean currents at the surface are mainly caused by this blustery force.
What is wind?
In the process of convection, this temperature of air sinks because it is denser than the surrounding air.
What is cold air?
The Coriolis Effect has this opposite effect on rotating storms in the Northern and Southern Hemispheres.
What is they rotate in opposite directions?

Clouds form during this stage of the water cycle.
What is condensation?
The Coriolis Effect causes these large circular currents to form in Earth's oceans.
What are Gyres?
The uneven heating of Earth by this creates convection currents in both the oceans and the atmosphere.
Without the Coriolis Effect, all wind would move in these two directions.
What are North and South?
