What source of energy below is the most important in driving the water cycle?

• Geothermal energy changes water to steam so condensation can occur

• Sunlight heats up Earth's surface water creating the process of evaporation

• Wind helps change surface water into water vapor during the process of evaporation

• Gravity is necessary to pull water downhill when it rains thus allowing water to flow into rivers and streams

Lab partners are designing an experiment that shows the important steps of the water cycle. For their experimental design, which of the following procedures could best be used to demonstrate the difference between condensation and evaporation?

• To show condensation- increase the temperature within the cycle; to show evaporation-decrease the temperature

• To show condensation- decrease the temperature within the cycle; to show evaporation- increase the temperature

• To show condensation- maintain a constant temperature within the cycle; to show evaporation- increase the temperature

• To show condensation- maintain a constant temperature within the cycle; to show evaporation-decrease the temperature

Refer to the diagram below of a student's lab setup of the water cycle. In this experiment, the total amount of water inside the container is measured at the beginning and then again after a full cycle has occurred. Which of the following best predicts the outcome of the experiment and explains why?

• The beginning amount of water in the container would be less than the ending amount of water in the container because the water evaporated, decreasing the water level.

• The beginning amount of water in the container would be more than ending amount of water in the container because the process of condensation increases the water level.

• The beginning and ending amounts of water in the container would be equal because the water that was evaporated increased the water level but then came back as precipitation which decreased the water level again

• The beginning and ending amounts of water in the container would be equal because the water that was evaporated decreased the water level but then came back as precipitation which increased the water level again.
