Answer to Question 1

Groundwater is an equalizer of streamflow and an agent of erosion.

Answer to Question 2

Porosity is the amount of pore space available to be filled with water within a substance. Permeability is the connectivity of that pore space and thus the ability of that material to transmit fluid. An aquifer is a porous and permeable material that contains groundwater. An aquitard is a layer that is not permeable and prevents or limits the flow of fluid.
