Chapter 1
Water that is safe for drinking is called this
freshwater
Water changing from liquid to gas is called this
Evaporation
Water vapor turns into liquid water when it does this
Cools
Moving air is called this
Wind
Dirty water that comes from sinks, toilets, and showers is called this
Wastewater
Most of Earth’s water is found in this place
Oceans
Water vapor cooling and forming clouds is called this
Condensation
Cooling water vapor causes this process to happen
Condensation
Water vapor in the air is part of this Earth system
What is the atmosphere
A process that removes solids from water is called this
Filtration
Only about this percent of Earth’s water is freshwater
3%
Rain, snow, sleet, and hail are all forms of this
Precipitation
Warm air can hold this compared to cold air
more water vapor
When warm air rises, it often carries this with it
water vapor
Gravel, sand, and charcoal are materials used in this process
Filtering Water
Why would a city like East Ferris run out of usable water even if water still exists nearby?
Because not all water is freshwater or easily accessible
Why does more evaporation often lead to more rain?
More water vapor in the air can form more clouds and precipitation
Why does rising air often cool down as it moves higher in the atmosphere?
Air pressure decreases, causing temperature to drop
Why might wind move moist air toward West Ferris but not East Ferris?
Wind patterns can carry water vapor in certain directions
Why do water treatment systems use multiple steps instead of just one filter?
Different steps remove different types of pollutants
Explain why East Ferris needs to find a new water source
Limited freshwater supply, increasing demand, water being used faster than it is replaced, population growth
Use the water cycle to explain why West Ferris gets more rain than East Ferris
→ More evaporation → more water vapor → more condensation → more precipitation
Explain why cooler temperatures over West Ferris cause more clouds to form
Cooler air leads to more condensation, creating more clouds
Use a system model to explain how wind, temperature, and water vapor interact to create more rain over West Ferris
Wind brings moist air, rising air cools, condensation forms clouds, rain falls
Use evidence to explain how a filtration system can help solve East Ferris’s water problem
It can clean wastewater into usable freshwater, increasing supply and reducing shortages
