Properties of Water
What property allows water to move upward through a plant’s stem?
What is capillary action?
What drives the water cycle?
What is energy from the Sun?
Which process connects surface water and groundwater?
What is infiltration?
What could best prevent loss of wildlife in wetlands?
Reduce pollution runoff into wetlands.
What human activity most often causes algae blooms?
Applying too much fertilizer.
Which property of water allows it to absorb a lot of heat before changing temperature?
What is high specific heat?
Why are warm ocean currents near the surface?
Because warm water is less dense than cold water.
What is the name of the underground layer that stores water?
What is an aquifer?
What family practice can reduce outside water demand?
Using non-potable or recycled water.
What type of pollution comes from a single, identifiable source?
What is point source pollution?
Why does ice float on water?
Because solid water is less dense than liquid water.
What part of the water cycle involves water vapor forming clouds?
What is condensation?
What is the main cause of groundwater depletion?
What is overuse for irrigation?
Which two Dust Bowl solutions reduced soil erosion?
Rotating crops and planting windbreaks.
What type of pollution comes from widespread runoff or multiple sources?
What is nonpoint source pollution?
What process involves water sticking to other materials?
What is adhesion?
What process releases water vapor from plant leaves?
What is transpiration?
What effect would high precipitation have on a lake and nearby groundwater?
Both water levels would increase.
What farming methods help minimize impact on climate change?
Cover crops, drought-tolerant plants, and leaving land untouched.
How did the Dust Bowl impact farmers and families?
Soil erosion and migration due to crop loss and poverty.
What process allows water to stick to itself, creating surface tension?
What is cohesion?
How do ocean currents affect global temperatures?
They distribute heat energy around Earth.
How is most of California’s freshwater transported from north to south?
By aqueducts.
What were Dust Bowl strategies mainly designed to protect?
Topsoil in farmland.
What would happen if a farmer over-fertilized soil before heavy rain?
Fertilizer would run off into water supplies, harming crops and ecosystems.
