From yesterday…..
• Why is the availability of water important to an ecosystem?– Plants need water to live & grow– Animals need water to live
• Is water a biotic or abiotic factor?
Information with Numbers
• What % of the Earth is covered with water?71%
• How much of the water is freshwater?3%
This includes water stored as ‘ice’……So there is actually very little usable freshwater
Water falls to Earth……..
-some soaks into the ground becoming GROUNDWATER!!
Groundwater Vocabulary
• Permeable-allows water to pass through• Impermeable- does not allow water to pass• Zone of aeration- unsaturated• Zone of saturation – water filled all pores• Water table – top of zone of saturation• Aquifers- groundwater stored in underground
layers
Groundwater Zones
Draw and label
• Zone of aeration• Zone of saturation• Water table• Lake• Well• trees
Groundwater Zones
AquifersWater that flows through the underground rock,
or stored in underground layers.
Warm-Up
• 1) Explain the difference between the permeable & impermeable rock layers discussed yesterday.
• 2) Compare and Contrast the Zone of Aeration and the Zone of Saturation.
Water falls to Earth……..
-gravity causes some to flow downhill as SURFACE WATER!!!!
-this is called runoff
SURFACE WATER
• Water that has NOT soaked into the ground• As it moves downhill,
– Forms water in streams & rivers
• Drainage Basin- area that is drained by a river & all the streams that empty into it
