and Correct Answers/ Latest Update /

Hydrologic Cycle
Ans: the circulation and distribution of water on the surface of
the land, underground, and in the air
5 processes of hydrologic cycle
Ans: condensation, precipitation, runoff, evapotranspiration,
infiltration
Condensation
Ans: water vapor in the air condenses to form droplets that
eventually merge and fall as rain

When does 30% of rainfall occur?
Ans: between november and april
When does recharge of aquifer systems take place?
Ans: Winter
Runoff
Ans: the water that does not soak into the ground or percolate
into aquifers
Unsaturated aquifers
Ans: absorb rainfall directly or through sinkholes
Saturated aquifers
Ans: cause runoff into lakes and streams

Evapotranspiration
Ans: evaporation and transpiration (evaporation from plants)
Florida evapotranspiration rate
Ans: high due to solar radiation levels
Permeability
Ans: speed with which water can move through soil
Rooting zone
Ans: only area where plants can absorb water with roots
What are the qualities of a sandy area?
Ans: high flow rate, as much as 6 ft deep rooting zone
What are the qualities of flatwood soils/pastureland?
Ans: 2-3 ft deep rooting zone

Ans: region below the land in which all the pore spac es in the
rock/soil are filled with water, "water bearing"
What percentage of Florida's drinking water do aquifers contribute to?
Ans: 90%
Two functions of aquifers
Ans: transmit groundwater from the point of entry to points of
discharge, store large volumes of water
Unconfined aquifers
Ans: water is free to percolate through an unsaturated zone of
soil or rock to the water table
Confined aquifers
Ans: water is confined under pressure by impermeable layer(s)
over the aquifer
Artesian wells
Ans: free-flowing wells caused by pressure in confined aquifers
