unsorted sand and rock
Which of the following materials is the LEAST porous?
Evaporation
adds water to the atmosphere
Desalination
allows saltwater to be used for drinking
Water
becomes less dense when it freezes
Confined aquifers are found
between two layers of impermeable soil

is the top of the saturated zone
As ocean depth increases
temperature decreases, pressure increases, salinity increases, density increases
Adhesion
water's attraction to other substances
Most lakes
were formed from melting glaciers
