Groundwater
I
I
Define infiltration
The process by which precipitation that has fallen in land trickles into the ground and becomes groundwater.
Define wells
The holes dug or drilled into the ground to reach an aquifer.
Define over-pumping
It is pumping faster than the water can be replaced.
Define cave
A natural underground opening with a connection to earth’s surface.
Water held underground in the soil or in pores and crevices in rock.
Define zone of saturation
The region below earth’s surface in which groundwater completely fills the pores of a material.
Define artisan aquifer
A confined and pressured aquifer sometimes resulting in a natural fountain.
Define permeability
Tendency of a material to let water pass through it.
Define sinkhole
A depression in the ground caused by the collapse of a cave or by the direct dissolution of limestone by acidic water.
Define spring
It is a natural discharge of groundwater.
Define zone of aeration
The layer above the zone of saturation where air occupies much of the pores.
Define water-table aquifer
An aquifer at the same level as the water-table.
Define porosity
The amount of pore space in a material.
Define stalactite
A form of drip stone that hangs from the caves’ ceiling like icicles and forms gradually.
Define hot spring
a warm or hot spring (self explanator)
Define aquifer
A body of permeable rock below the earth’s surface which can contain or transmit groundwater.
What is the difference between ordinary and artisanal wells
Ordinary wells are dug or drilled into the ground and their water level is the same as the water-table. Artesian wells are formed from artesian aquifers where water that is under pressure spirts from the ground.
What are the three ways in which aquifers can be damaged
Aquifers can be damaged by overuse, subsidence, pollution to groundwater.
Define stalagmite
As water drips to the floor of a cave, it may also slowly build mound-shaped dripstone.
Define geyser
It is an explosive hot spring.
Define aquiclude
An impermeable area that blocks groundwater.
What is the difference between aquifers and aquicludes
Aquifers hold or transport groundwater while aquicludes block groundwater.
Define drawdown
The difference between the original water-table level and results in a cone of depression around the well.
Define recharge
Water from precipitation replenishes the water content of an aquifer.
Which is harder to clean out of groundwater- salt or chemicals and why
Chemicals because the small molecules can pass through rocks and filters unlike salt.
