-is a structure below the surface of the ground that carries water and
can serve as a source of water.
-is a well in which water shoots out of the ground.
-artesian well diagram
-is a gas denser than air; each molecule consists of one carbon atom and two
oxygen atoms. Carbon dioxide is used to produce the bubbles in soda pop.
-is carbonated water; a weak acid made of carbon dioxide and water.
This acid can eventually cause the decomposition of most silicate minerals.
-is an underground cavity.

-New Mexico, Carlsbad Caverns-2
cave formation process
-A standard limestone cave needs four factors to form: relief, limestone, fractures,
-making a cave
-is also known as dripstone. Cave onyx consists of banded layers of calcite deposited
within a cave.
-New Mexico, Carlsbad Caverns-Lumpy And Bacon Slab Stalactites
-calcite onyx cabochon-1
-calcite onyx cabochon-2
-is the same as a cave, but you can charge more admission if you call it a cavern.
-New Mexico, Carlsbad Caverns-large cave
-is a cave feature made of dripstone that forms when a stalactite and a stalagmite merge together.
-New Mexico, Carlsbad Caverns-large column
cone of depression
-occurs as the water table drops in the vicinity of the well due to ooverpumping.
-cone of depression
-is a quantity of contaminated groundwater moving beneath the surface.
-consists of layers of minerals deposited inside of a cave, usually as stalactites or
-New Mexico, Carlsbad Caverns-stalactites and stalagmites
-is a measure of how fast the temperatures rises with depth.
-is an explosive eruption of hot water and steam from a hole in the ground.
-If over pumping has continued for a long time, the surface of the ground drops.

-warning about earth fissures
-is water in found in the ground.
-is a twig like stalactite often covered with crystals.
-aragonite cave formation
-calcite cave formation
-A supply of water at a high elevation that is connected to an enclosed body of water at a lower
elevation creates pressure in the lower body. Typically the pressure increase is about 1 pound of
pressure for every two feet of the water column.
-hydraulic head-Opal's Pals
-is H2S, a stinky gas associated with certain hot springs, such as in Yellowstone National Park.
It is also a major component of sewer gas.
-is created by hot mineralized water coming from an igneous intrusion that then changes
the composition and structure of the minerals in the surrounding country rock.
-hydrothermal alteration-close up
-California, Lassen Peak-hydrothermal alteration of volcanic ash
-is a landscape marked by sinkholes and underlain by a large number of limestone caves.
-is a chemical process in which water moving through permeable rock materials dissolves
some minerals and then carries these minerals to another area.
-Water getting into a joint leaches out some minerals and deposits others in a curved
semi-concentric pattern which can be observed when the altered rock is broken..
-is a cave in which mineralized dripping water is still present and stalactites and stalagmites
are still growing.
-is created when an open fracture is filled with minerals deposited by hydrothermal action.
-is where water flows out of the ground.
Old Faithful Geyser
-is the most famous geyser in Yellowstone National Park in Wyoming.
-Yellowstone-Old Faithful Geyser
-Old Faithful Geyser
-occurs when groundwater is pumped out of the ground faster than new groundwater can flow into
the area and maintain the same level of the water table.
-cone of depression diagram
-is semi permanently frozen ground.
-is the ability of a fluid to flow or pass through a material.
-is a measure of the amount of open space in a rock. It is also the measure of how much liquid can be
stored within the rock.
-is a funnel-shaped topographic feature in which water drains downwards at the bottom of the sinkhole.
These depressions can form directly over caves or may result as a collapse features which were undermined
by the dissolution of the underlying ground.
-is a cave dripstone feature that hangs down from the ceiling of a cave.
-New Mexico, Carlsbad Caverns-stalactites-1
-New Mexico, Carlsbad Caverns-stalactites-2
-New Mexico, Carlsbad Caverns-lumpy and bacon slab stalactites
-is a cave dripstone feature that forms on the floor of a of cave.
-New Mexico, Carlsbad Caverns-stalactite and stalagmite approaching each other
-New Mexico, Carlsbad Caverns-stalactites and a large stalagmite
-is the top of the saturated zone. The water table is the level to which water will rise in a well.
Yellowstone National Park
-is a large area in the northwest corner of Wyoming that is famous for its geological attractions of geysers, hot springs,
boiling mud pots, and waterfalls.

zone of aeration
-is the region of the ground above the water table where the spaces between grains are mostly filled with air.
