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
