Multiple Choice

Approximately what percentage of Earth's water is freshwater?

• 2.5%

• 30%

• 68%

• 97%

Multiple Choice

Which of the following are processes that move water between pools in the water cycle?

• Evaporation

• Condensation

• Precipitation

• All of the above

Open Ended

Describe the role of evaporation in the water cycle and identify its major sources.

Multiple Choice

What role does the Sun play in the water cycle?

• It provides energy for evaporation.

• It causes precipitation to fall.

• It cools water vapor to form clouds.

• It absorbs water from the soil.

Open Ended

Explain how condensation is essential for precipitation to occur in the water cycle.

Multiple Choice

What is the main function of runoff and streamflow in the water cycle?

• Collects precipitation and snowmelt

• Forms clouds and fog

• Absorbs solar energy

• Releases water vapor from plants

Multiple Select

Which of the following factors affect the rate of infiltration into the ground?

• Soil type

• Vegetation

• Slope

• Wind speed

Multiple Choice

Which process allows water to soak into the ground from the surface, recharging soil moisture and shallow groundwater?

• Infiltration

• Evaporation

• Condensation

• Transpiration

Multiple Choice

What role does latent heat play in the transport of energy into the atmosphere?

• It allows water vapor to carry energy upward during state changes.

• It prevents water from evaporating.

• It cools the Earth's surface.

• It causes precipitation to fall.

Multiple Select

Based on the information from the slides, which of the following are characteristics of groundwater?

• It fills tiny gaps between soil and sediments underground.

• It is mostly used for agriculture.

• It is only found in lakes and rivers.

• Its level can rise and fall depending on rainfall and pumping.

Multiple Select

Which of the following statements about the capillary fringe are correct?

• It is located right above the water table.

• Water is pulled upward by capillary action in this zone.

• Plant roots cannot access water in this zone.

• It is part of the saturated zone.

Multiple Choice

Which of the following best describes a confined aquifer?

• It is trapped between layers of less permeable rock or clay and is under pressure.

• It is directly open to the surface and its top is the water table.

• It is always above the water table.

• It cannot transmit water.

Multiple Choice

Which of the following best describes the process of aquifer recharge?

• Water is pumped out of the aquifer for human use.

• Water enters an aquifer when rain, snowmelt, or rivers seep down through soil and rock.

• Water leaves aquifers through springs and wetlands.

• Water evaporates from the surface of the aquifer.

Open Ended

Explain how aquifers support ecosystems and why they are important during dry periods.
