A cone-shaped deposit of calcite on the ceiling of a cave is called a

• cavern.

• stalagmite.

• stalactite.

• column.

When karst topography forms in dry regions, sinkholes may form very close together and form dramatic arches and

Rock becomes chemically weathered when

• the water table drops below sea level.

• toxic wastes leak into the groundwater.

• the rock becomes impermeable.

• carbonic acid dissolves minerals in the rock.

Calcite formations standing on the floor of a cavern are called

• stalactites.

• aquifers.

• stalagmites.

• depressions.

A region that clearly shows the results of chemical weathering is called

• sink topography.

• limestone topography.

• karst topography.

• an artesian formation.

Uncollapsed rock between sinkholes can form arches called

• columns.

• subsistence sinkholes.

• natural bridges.

• recharge zones.

The layer of an aquifer in which the pore space is completely filled with water is called the zone of

• aeration.

• saturation.

• capillaries.

• porosity.

A second water table that sits above the first water table is called a(n)

• gradient.

• capillary fringe.

• aquifer.

• perched water table.
