The term used to describe groundwater rising to the surface due to pressure in an aquifer is artesian well.

Here's why:

* Artesian aquifer: An aquifer where groundwater is confined between layers of impermeable rock or clay. This pressure forces the water upward, sometimes even to the surface.

* Artesian well: A well drilled into an artesian aquifer where the water rises above the level of the aquifer, often without the need for pumping.
