What is the primary factor that determines the porosity of a material?

• Particle size

• Particle shape

• Particle arrangement

• Particle density

Which of the following materials is likely to have the highest porosity?

• Granite

• Sandstone

• Clay

• Limestone

How does porosity affect the storage capacity of an aquifer?

• Higher porosity increases storage capacity

• Higher porosity decreases storage capacity

• Porosity has no effect on storage capacity

• Porosity only affects permeability, not storage
