Here's a breakdown:
* Permeable: Means the rock has spaces (pores) that allow water to flow through it.
* Aquifer: A body of rock or sediment that can store and transmit groundwater.
There are two main types of aquifers:
* Unconfined aquifer: An aquifer where the water table is the upper boundary. It's directly connected to the surface and can be easily recharged by rainfall or snowmelt.
* Confined aquifer: An aquifer that is sandwiched between two layers of impermeable rock (like clay or shale). The water pressure in a confined aquifer is higher than the surrounding atmosphere.
