Groundwater Precipitation.
Artesian springs form where pressurized water flows through cracks in cap rock.

Water moves downhill as "runoff." It also moves through the ground in porus matierials like sand or gravel, or through cracks or channels in bedrock. Water seeks the lowest level where it forms groundwater, streams, rivers, lakes and oceans. Skye
1 Running water on the surface of the earth erodes the land. Groundwater also can cause erosion under the surface. As water flows through the soil, acid is formed. This acid can cause minerals to be dissolved.2 Minerals that are carried in groundwater can also be deposited in other places. This cycle of erosion and deposition can cause underground caves to form. This happens especially in areas where there is limestone below the surface.3 A cave is an underground opening. It has a connection to the surface of the earth. A cave is formed by the erosion of limestone under the ground. The acid water moves through the cracks in the limestone and makes them larger.
places where groundwater bubbles or flows out of cracks in the rock is called springs.

A non example of runoff is groundwater because groundwater, the water flows under the ground and as for runoff the water flows over the land's surface

it moves because rigo said so Groundwater is not "held" in one place underground--it flows through the aquifer. Groundwater is transported through aquifers because of two main reasons: gravity and pressure. In unconfined aquifers, which we concentrate on because they are more likely to be contaminated, water always flows from high points to low points because of gravity.

Aquifer.
It is a geode. Geodes form in gas bubbles in cooled porous lava flows. Groundwater provides the minerals that crystallize inside these hollow bubbles. Eventually erosion removes the lava rock that provided the mold that shaped the outside of the geode and then humans find them (and usually cut or crack them open to look at the crystals inside).
