a material that has high porosity and high permeability a material that has high porosity and low permeability a material that has low porosity and high permeability a material that has low porosity and low permeability
I am hesitating between 4 options to answer the following question, which option should I choose?
Question: The empty spaces in a material are called pores. Porosity is the amount of empty space within a material. Permeability describes how well the pores in a material are connected. Which of these materials would make the most effective aquifer?
Possibilities:
- a material that has high porosity and high permeability
- a material that has high porosity and low permeability
- a material that has low porosity and high permeability
- a material that has low porosity and low permeability

a material that has high porosity and high permeability
