ECOREGIONS OF TEXAS: WATER SHEDS & AQUIFERS ECOREGION: a region that is smaller than a biome, and is defined by its: * location * climate * plants (vegetation) * animals

Slide 2

KEY TO REGIONS 1. Piney Woods 2. Gulf Prairies/Marshes 3. Post Oak Savannah 4. Blackland Prairie 5. Cross Timbers/Prairie 6. South Texas Plains 7. Edwards Plateau 8. Rolling Plains 9. High Plains 10. Trans-Pecos

Slide 3

What is a Watershed? A watershed is: * The area of land where all of the water on it drains off of * All the water drains into the same low-lying place called a basin * Watersheds can be mountains, hills, drainage ditches, bayous, fields, streets, etc * There are 2,110 watersheds in the Continental USA

Youtubevide: What is Groundwater: http://youtu.be/oNWAerr_xEE?list=PLhW3-DBLasDwIa_TCDSYy9xhVT243YIp0 WHAT IS GROUNDWATER?

Slide 9

AQUIFERS * Are underground layers of rock that are saturated (filled) with water that can be brought to the surface through natural springs or by pumping. * The groundwater contained in aquifers is one of the most important sources of water on Earth * About 96 percent of our freshwater is groundwater *The rest is found at the surface in streams, lakes, rivers and wetlands.

BRAINPOP: http://www.brainpop.com/science/earth system/groundwater/preview.weml DRILLING WELLS: to get drinking water from AQUIFER Some of the best places to drill are along the sides of valleys where the well will be high enough to avoid flooding but can reach to the bottom of the valley where the water is stored. A B Wheres the best location to drill a well? A or B

Slide 13

Locations of Water Watershed- The land from which surface runoff (rain or snow melt) drains into a stream or lake (called a water basin) Runoff- Water that doesnt soak into the ground or evaporate flows across surface to lower ground (back to lakes and oceans) Surface water- Precipitation, water pooling or flowing across grass, soil, pavement towards river or sewers Percolation water moving downward through openings in the soil Ground water- water below the surface of the Earth. Moves slowly through soil particles (pores in between) Aquifer - Are underground layers of rock that are saturated (filled) with water that can be brought to the surface through natural springs or by pumping.

Slide 14

Aquifer Aquifer- a layer of permeable rock (like limestone) that allows water to flow thru freely Aquifer Recharge Zone- areas at a crack or fault where water runs into aquifer Zone of Saturation- any permeable rock pores are saturated or filled up with water Water Table- upper surface of zone of saturation

Slide 15

On the bottom 1/3 of your paper, please include a picture of the aquifer Impermeable Rock (bedrock)

Slide 16

Groundwater (write on the bottom 1/3 of paper) Permeable water passes thru soil/rock freely (ex: limestone) Semi permeable some water passes thru Impermeable NO water passes through (bedrock)
