1. Water Cycle and Groundwater Chapter 9

2. Draw a picture below of what you remember of the water cycle: Now examine page 185 in the workbook and add on any new terms to your diagram above (or draw a new one below).

3. Define the following Terms: GROUNDWATER, TRANSPIRATION, PRECIPITATION, INFILTRATION, HYDROLOGIC CYCLE Define the following Terms: GROUNDWATER, TRANSPIRATION, PRECIPITATION, INFILTRATION, HYDROLOGIC CYCLE GROUNDWATER: water that seeps into the ground;subsurface water GROUNDWATER: water that seeps into the ground;subsurface water PRECIPITATION: any form of water falling from clouds PRECIPITATION: any form of water falling from clouds INFILTRATION: process whereby water seeps into the gound INFILTRATION: process whereby water seeps into the gound TRANSPIRATION: process whereby plants give off water TRANSPIRATION: process whereby plants give off water HYDROLOGIC CYCLE: the water cycle HYDROLOGIC CYCLE: the water cycle

4. 4. How much of Earth’s surface is covered in water? 5. Where is most of that water found? Give percents 97% salt water, 2% frozen, and 1% drinking water 71%

5. See pages 302-303 in textbook and copy and label the illustration of the water table. Include groundwater zones. Use colored pencils. See pages 302-303 in textbook and copy and label the illustration of the water table. Include groundwater zones. Use colored pencils.

6. Define the following groundwater zones: ZONE OF AERATION: zone or layer of soil with air pockets or pores ZONE OF AERATION: zone or layer of soil with air pockets or pores WATER TABLE: “stream” of water flowing underground; flows downhill with gradient WATER TABLE: “stream” of water flowing underground; flows downhill with gradient ZONE OF SATURATION: zone or layer of soil where the pores are filled with water ZONE OF SATURATION: zone or layer of soil where the pores are filled with water IMPERMEABLE ROCK: zone or layer where water cannot infiltrate or go through IMPERMEABLE ROCK: zone or layer where water cannot infiltrate or go through

7. FACTORS THAT DETERMINE WHETHER WATER INFILTRATES: A. Pore space available (porosity) A. Pore space available (porosity) B. If the water can seep in (permeable) B. If the water can seep in (permeable) C. Type of sediment (sorted or unsorted) C. Type of sediment (sorted or unsorted) D. Topography of the land-steep slope verses flat land D. Topography of the land-steep slope verses flat land
