1. POROSITY is the open space in soil.
The more open space, the greater the POROSITY.

2. PERMEABILITY is related to POROSITY.
BUT THEY MEAN DIFFERENT THINGS.

3. As the porosity of a soil sample increases
1) Its permeability remains unchanged
2) Its permeability increases
3) Its permeability decreases
4) It becomes impermeable

4. Different ground has different porosity.

5. Porosity IS NOT effected by size.=
Less pores,
but bigger
More pores,
but smaller
Porosity IS effected by...

6. Packing of Grains Shape of Grains Mixed Sizes of Grains Less porous
More porous
Less porous
Packing of Grains
Flatter sediments are less porous
Shape of Grains
Mixed Sizes of Grains

7. NONE, they are all equal! Which beaker has the greatest porosity?
Which beaker has the largest sized pores?
Which beaker has the greatest porosity?
NONE, they are all equal!
(more small pores = less big pores)

8. THEY ARE ALL EQUAL! Which beaker can hold the most water?
(more small pores = less big pores)

9. (1) A & C (2) B & D (3) C & D (4) D & A
The diagram shows columns A, B, C, and D that contain different sediments.
Water was poured through each column. Which columns of sediment has the most space for water?
(1) A & C (2) B & D (3) C & D (4) D & A

10. The diagrams below represent three containers, A, B, and C, which were filled with equal volumes of uniformly sorted plastic beads. Water was poured into each container to determine porosity and infiltration time.

11. Which data table best represents the porosity and infiltration time of the beads in the three containers?
