Water cycle

INFILTRATION
Factors that affect the amount of water that seeps into the ground (infiltration)
1. Type of rock or soil on which the water falls

*POROSITY- The amount of PORE SPACE between the particles.
Depends on:
Particle shape and sorting
Diagrams-
Sorted
Unsorted
Angular
Rounded
Shape
Sorting
(Factor 1: Type of rock or soil continued)
*
Permeability
RATE at which water passes through pore space
* Water passes easily through materials with more pore space
(usually)
* Fine grained particles are usually less permeable or IMPERMEABLE
(shales and clays)







NOTE~ a material can be porous and not permeable. HOW????
Capillarity-how much water "sticks to" the particles
One day water said:
Smaller particles retain more water.
Unsorted particles retain more water.
2. Climate
In a hot and dry climate
Evaporation ____________

Infiltration _______________
3. STEEPNESS OF SLOPE
As gradient increases
Runoff_________________
Infiltration_____________
4.VEGETATION
As vegetation increases
Runoff______________
Infiltration___________
Transpiration__________
5. LAND USE
Populated places = more pavement
Infiltration ________________
As particle size increases capillarity __________
How come?
Which has greater capillarity?
Which retains more water?
HOLY SPONGEBOB!!!
The holes are not connected!
Which has the greatest particle size?
As particle size increases permeability ____________________

(Other factors that affect infiltration)
How permeable is frozen ground? Why?
Where does your water come from?
Find the impermeable layers.
Why is it important to dispose of toxins properly?
The End
salt water encroachment
