Aquifer are underground areas of saturated permeable rock or sediments above layers of impermeable rock that have the ability to hold/retain ground water, preventing it from percolation and infiltration, thereby serving as a form of natural water storage .
if it is a sedimentary rock the fossils get cemented together
it forms a sedimentary rock
When rock layers are folded, a geological fold happens. These folds form under various conditions such as stress, hydrostatic pressure, pore pressure, and temperature gradient.

The slab of volcanic rock that is formed when magma forces itself across rock layers is called a dike. This will eventually build into mountains.
Aquifers are permeable layers of rock that have non permeable layers of rock under them so water remains in the permeable layers
Aquifers are made of permeable rock layers
Permeable rock strata are called aquifers.
Aquifers.
Aquifers are layers of rock that hold a lot of water and allow it to circulate.
Usable groundwater is to be found in aquifers. Aquifers are porous, permeable rocks sandwiched between two layers if impermeable rocks. Sandstones and porous limestones can form good aquifers.
a water-bearing stratum of permeable rock, sand, or gravel
aquifers
This type of layer is found within the earth and is called an Aquifer.
Aquifers are layers of rock (primarily limestone) that gather water in thier porous holes. People have made machines to extract this water, and they are very useful. Aquifers are used primarily in the coastal plains region of the USA.
When water moves on to of rock, the rock becomes what is called an aquifer. Aquifers must be both permeable and porous. Aquifers may occur at various depths.
Subsurface water is found in layers called aquifers.
