The water cycle |
|
|
Water is found ____ and ____ Earth's surface |
Above and Below |
|
|
Water seeps through the ground through the forces of gravity and capilary action known as |
infiltration |
|
|
As slope______, infliltration __________ |
SLOPE DECREASES INFLILTRATION INCREASES |
|
|
Ground without vegetation usually has _______ run off and _____ infliltration |
HIGH RUN OFF |
|
|
Water will infiltrate until it reaches the _____ |
zone of saturation |
|
|
Define zone of saturation |
Area where spaces between particles are filled with water |
|
|
Zone of aeration |
area where spaces between particles are filled (with water) and partly with air. |
|
|
A full body of water underground is known as an ___ |
aquifer |
|
|
Auqifers exist under layer of ______ and _____ |
permeable rock and sediment |
|
|
The line seperating the soil and the aquifer is known as the ______ |
water table |
|
|
When the land __________ the water table, a new body of surface waters is formed fromt he water stored in the aquifer. IF the surface water dries up, the aquifer can replenish the water |
dips below |
|
|
When the group water moves out and onto the surface of the Earth, they can form streams of water. These areas of released ground water are known as_______ |
Springs |
|
|
Most springs are the result of water not able to reach an _____ |
aquifer |
|
|
Capillary action descrbes the attractive forces of ______-, which explains how water can move against gravity towards the capillary fringe, just above the water table |
water to soil |
|
|
Particle size and _____ can affect capillarity |
loose materials |
|
|
capillarity can also decrease the effect of _____ |
infiltration |
|
|
Porosity |
The percentage of pore space or open space in a material |
|
|
Rounded shape will create _______ porosity |
Greater |
|
|
A loosely packed soil will create _______ porosity |
Greater |
|
|
Sorted particles will create _______ porosity |
greater |
|
|
Permeability: |
The rate at which water will flow or move through a material |
|
|
Run off can occur when: 1. Rate of precipitation exceeds the permeablty rate of the soil 2. __________ 3. SLope is too great for infiltration 4. Water at the surface has not evaporated |
Pore spaces are saturated |
|
|
Most runoff travels to streams where it is carried to ________ |
the oceans |
|
|
Ordinary well |
a well that is dug to the zone of saturation. This type of well can take in the groundwater that is below the water table |
|
|
Artesian Well |
a well that is dug into an artesian aquifer. THis type of well reduces the chance of receiving contaminated water |
|
|
Some water from artesian wells or springs may be _______ |
much warmer |
|
|
The water rises and breaks through cracks in the surface, known as a ______, reaching temp. to 143*f |
hot spring |
|
|
Geyser: |
A hot spring that shoots colimns of hot water and steam into the air. |
