size of the particles in the material
shapes and uniformity of the material
amount of cementing agent in the pore space of the material
All of the above are correct.
The permeability and porosity of an aquifer is very high, air and pretty much any liquid can pass trough it with ease. Where as shale has very little porosity making it virtually impossible for air or liquid to pass through.
clay and solid rock has porosity
Yes, clay is more porous than sand. Typical porosity of silt and clay is 35-50% and 33-60%, respectively. Sand has porosity of 20-35%.
An aquifer is an underground fresh water source.
aquifer is the correct answer
The characteristics to consider in this case include; the aquifer material, porosity, permeability, and aquifer depth.
The permeability and porosity of an aquifer is very high, air and pretty much any liquid can pass trough it with ease. Where as shale has very little porosity making it virtually impossible for air or liquid to pass through.
The larger the particle size, the higher the porosity. Also keep in mind that angular particles have a higher porosity than round particles. *Good way to remember porosity is that the spaces between particles are "pore-like."
Porosity refers to the measure of how much of a rock is open space. The two factors concerning particles in a rock that have the greatest effect on the rock's porosity are shape and distribution.
size and shape are 2 of them
Shape and Distribution
shape and sorting
Factors that affect evaporation include temperature, humidity, wind velocity, exposed surface area, porosity of soil, grain size of soil particles, soil water content, matric potential, and sun intensity.
An aquifer is a body of permeable rock that can contain or transmit groundwater. Some factors that affect potential aquifers are permeability, thickness and hydraulic properties.
big particles=low porosity small particles=high porosity
Ang kahulugan ng "porosity" sa Tagalog ay "papak" o "bukas-bukas." Ito ay tumutukoy sa dami o kahabaan ng mga butas o espasyo na makikita sa isang bagay tulad ng lupa o kahoy.
