Energy and the Water Cycle
the sun
Gaining Energy
What is the movement of air called?
Wind
What is a phase change?
A change in the state of matter (solid, liquid, gas).
What is the main source of energy INSIDE Earth
Core
What process turns liquid water into water vapor
Evaporation
When water changes from gas to liquid what is happening to its energy
Losing Energy
What causes air and water to move in convection currents?
Uneven heating by the Sun.
What happens to air when it is is heated by the sun?
It Rises
What is an observation in an experiment
Using your senses to notice something in an experiment.
what process happens when water vapor cools into droplets?
What do we call the small water drops that form on cold surfaces?
Condensation
When air warms up, what happens to its pressure and density?
It becomes less dense and pressure decreases — it rises.
Explain cause and effect in this sentence: “When the Sun heats water, vapor forms.”
Cause = heat energy; Effect = water evaporates.
When is your next test?
12/18
How does gravity help move water in the cycle?
It pulls water down as precipitation
What does condensation in our atmosphere form?
Clouds
When air cools down, what happens to its pressure and movement?
It becomes more dense and sinks.
How does energy move during evaporation and condensation?
Evaporation = energy absorbed, Condensation = energy released.
Can you tell me the capital of California?
Sacramento
Explain how energy from the sun and gravity work together in the water cycle
The sun causes evaporation; gravity returns water to Earth
What is happening during Condensation?
Water Vapor loses energy and becomes water droplets
Explain how convection connects to wind formation.
Warm air rises, cool air sinks, creating a cycle — that’s wind!
What kind of energy is starting the water cycle and convection cycle
Heat, Sun Energy
What is Mr. Z's favorite thing to say?
