Grade 5 Water Cycle, Weather, Climate

Your lab team has selected an experiment to determine the effects of temperature on the rate of evaporation. They have filled 4 plastic cups with water at different temperatures. Each cup of water is covered with another plastic cup that is turned upside down. They then begin to observe the amount of condensation that is collected in the top cup. What phase of the water cycle is being modeled when water falls from the top of the cup back to the bottom?

• Precipitation

• Evaporation

• Freezing

• Condensation

What is the effect of temperature on the evaporation of water?

• The lower the temperature, the higher the evaporation rate

• The higher the temperature, the higher the evaporation rate

• The higher the temperature, the lower the evaporation rate

• There is no relationship between temperature & evaporation rate

The water cycle is a continuous movement of water on, above, and below the surface of the Earth. The water cycle is called a "cycle" because there is no beginning or end. Water can exist as a solid, liquid, or gas at various stages of the water cycle. Which of the following BEST explains how water is changed from one state to another as it moves through the environment?

• Evaporation-Precipitation-Condensation-Run-off

• Evaporation-Run-off-Condensation-Precipitation

• Run-off-Precipitation-Condensation-Evaporation

• Evaporation-Condensation-Precipitation-Run-off

Jenny and her family are on vacation in the Hawaiian Islands. One of the islands they visit has an area where it rains every day. Which statement below would explain how constant rain (precipitation) over a period of time would affect the landscape on this Hawaiian Island?

• There would be no obvious change to the landscape

• The island would change shape due to weathering & erosion

• The island would disappear completely due to flooding

• The island would collide with other islands, forming an earthquake

Air expands as it gets warmer, so it can hold much more humidity than cold air. The amount of humidity increases as the liquid water on the surface of the Earth evaporates into the atmosphere. Which tool is used to measure moisture content in the air?

• 
• 
•

Constance and her family visited an area in San Gorgonio that relies on wind energy to fuel wind turbines. The tour guide explained that the wind speed would need to be about 14 miles per hour before the wind turbines can generate electricity. Constance wondered what caused the wind to blow and how reliable wind energy is in providing electricity to the factories and schools in the area. Which of the following statements is the BEST explanation that the tour guide could give to Constance about the cause of the moving wind?

• Uneven heating of the Earth causes currents from outer space to cause the turbines to move

• Uneven heating of the Earth creates areas with different air pressure, which causes air to move from high to low pressure areas

• The revolution of the Earth around the Sun causes wind currents

• The wind is fueled by wind turbines that receive electricity from power lines
