Water Cycle & Phase Change

What is the energy source for the water cycle?

• the sun
• the earth
• water
• the moon

What happens to the movement of particles as they cool down?

• They slow down
• Nothing
• They don't move
• They speed up

What happens to particle movement/speed when energy is added to a phase?

• Particles slow down
• Particles go faster
• Particles don't move
• Particles stay the same speed

Which two phases changes add energy/need more energy?

• Freezing, Melting
• Condensation, Evaporation
• Freezing, Condensation
• Melting, Evaporation

Which two phases changes takes away energy/lose energy?

• Freezing, Melting
• Condensation, Evaporation
• Freezing, Condensation
• Melting, Evaporation

When energy is added or taken away from a substance it causes a:

• Chemical Reaction
• Phase Change
• Nothing Happens

What happens to the distance between particles when energy is added to water? 

• Particles move farther apart

• Particles move closer together

• Particles stay the same

As a sample of water turns to ice

• new molecules are formed as the water gains thermal energy
• the mass of the sample is increased as the water gains thermal energy
• the arrangement of the molecules changes as the water loses thermal energy
• thermal energy is absorbed by the molecules, resulting in a change of state

The diagram shows the process of evaporation over the ocean.
What is the most likely effect of this process on the land areas nearby?

• Increased drought conditions
• Decreased erosion of the shoreline
• Increased precipitation
• Increased solar energy

Which of the following best models the interaction between water and the sun's heat energy during precipitation?

• 
• 
• 
•
