show The water table is the top level of groundwater in an aquifer.  
🗑
What is the same about the words evaporation, condensation, precipitation, and sublimation?   show
🗑
show No, water must first evaporate into the atmosphere before it can condense and fall back to Earth as precipitation.  
🗑
How much of Earth's surface is covered by water?   show
🗑
show 3/100  
🗑
show About 25 percent  
🗑
What would Earth be like if the hydrosphere covered only 25 percent of its surface?   show
🗑
show It gets warmer  
🗑
How would a mouthful of ocean water taste?   show
🗑
show Southern Florida- It is warmer in southern Florida, so evaporation is faster.  
🗑
show Cold water is heavier than an equal volume of warm water.  
🗑
show Salinity  
🗑
show In warmer areas, water evaporates quickly, so warm ocean water has higher salinity.  
🗑
show Rain or snow  
🗑
show Groundwater  
🗑
What occupies an aquifer?   show
🗑

🗑
show The water table

🗑
What acts as a filter to remove small particles from water that flows through it?   show
🗑
show Water is treated to kill bacteria and remove pollutants.  
🗑
How could pollutants get into groundwater?   show
🗑
What are formed when parts of ice break off from glaciers or ice sheets?   show
🗑
show To filter out harmful chemicals and bacteria.  
🗑
show Water vapor  
🗑
What are the five steps of the water cycle?   show
🗑
What is another possible path in the water cycle- when ice changes directly to water vapor without melting first?   show
🗑
What is the changing of liquid water to water vapor (gas)?   show
🗑
show Condensation  
🗑
What is it called when the water falls from clouds as rain, snow, sleet, or hail?   show
🗑
show Rivers, Streams, Lakes and Ice  
🗑
show A watershed  
🗑
What forms when water vapor turns into ice crystals?   show
🗑
show During Respiration  
🗑
show Sunlight, or the sun  
🗑
What is needed to raise water vapor to the clouds and move it by winds?   show
🗑
show Yes, it is heat  
🗑
What warms the air or water in the immediate area?   show
🗑
show The soil  
🗑
When groundwater slowly moves through aquifers into rivers, lakes and the ocean, how many years can it take?   show
🗑
show Oceans, Lakes, Rivers and Puddles

show Melting, Evaporation, and Sublimation  
🗑
show Frost and Dew  
🗑
