- What is ground water?
- water that seeps into the soil
- What is surface water?
- water that flows over the surface
- Where is surface water found?
- lakes, rivers and streams
- What is zone of saturation
- the lower layer of soil that has all pore spaces filled with water
- What is zone of aeration
- the upper layer of soil that has pore spaces filled with water and air
- What is pore space
- spaces between soil particles
- What is the water table
- the boundary that separates the zone of saturation and the zone of aeration
- 5 steps ground water takes
-
1- water seeps into ground
2- water hits rock and can't go farther
3- water fills the pore spaces
4- lower layer of soil becomes filled with water
5- upper layer of soil is filled with water and air - What is the head of stream
- beginning of a stream where a channel is cut into the land
- What is the mouth of stream
- the point at which the stream empties into another body of water
- What is the stream channel
- course along which the stream flows
- What is a delta
- a flat plain created by the sediment dropped at the streams mouth
- which soil has more space - clay or sand?
- sand because in our experiment we poured water on top of both and it seeped through the sand but not the clay
- What is the difference between ground water and surface water?
- Ground water is fresh water hidden underground. Surface water is fresh water that comes from lakes and streams.
- 4 steps to getting water from a well
-
1- drill hole deep into ground
2-put a plastic or steel pipe into hole
3-attach an electric pump to the pipe
4-pump will push water upward through pipeinto home - How do utility companies clean water?
-
-add chemicals
-remove the sediment
-bubble air into it to make it fresh - What is erosion?
- water wearing away rock and soil
- What is the water cycle?
-
-sun heats water
-water turns to ags called water vapor and rises(evaporation)
-as goes higher -gets colder- turns back to liquid
-water drops stick together and form cloud (condensation)
-precipitation - rain, sleet or snow
