groundwater
When magma comes in contact with underground water, it creates hot springs, or geysers.
underground aquifers
Here's a hint: glacier ice comes from precipitation, aquifer water comes from a hole in the ground where minerals are. Ever hear of colligative properties? Specifically, freezing point depression?
Pressure from underground pushes water up to the surface.
Percolation affects the movement underground because, when the water is passing through it dissolves all salt and minerals.
Caverns can be under water and underground.
caverns
Caverns are typically formed through a process known as karstification, where groundwater dissolves soluble rocks like limestone and carbonate rocks over time. This dissolution, along with other factors such as erosion and tectonic forces, can create underground cavities and passageways that eventually turn into caverns.
water seeps through the ground and dissolves the limestone bedrock.
Caves
Under ground Caverns are Caused When a New Lake is being Formed, That keeps a Cave under the lake that soon Collapse Because the wieght of the lake/Water, Causes Erosion That Then Is Deposition because the Lake water fills up The under ground Cave.
There are two possible meanings: One: an underground map is used to show the stations on an underground railway system. Two: an underground map could be used to show caves, mines, and caverns, etc, that has been explored and surveyed by pot-holers. ANS 2 - Underground maps show aquifers and similar bodies of subterranean water.

A spring
Bluespring Caverns, located in Indiana, was formed through a combination of natural geological processes. The caverns were created by water dissolving the limestone bedrock over thousands of years, resulting in the formation of underground passageways and chambers. The constant flow of water continues to shape and modify the caverns to this day.
