properties of water
expands as a solid, neutral ph, high specific heat
what is cohesion
attraction of water molecules have to other water molecules
what is adhesion
attraction of water molecules to other substances
what is transpiration
water vapor leaving plant leaves
what is condensation
water going into gas to water (what forms clouds)
what is precipitation
water released from clouds in various forms
what is evaporation
water changing from liquid to gas
what is infiltration

what is a watershed
is an area of land that drains into a particular body of water
what are headwaters

what is an estuary
where the mouth of the river mixes with the ocean - makes brackish water

Chesapeake Bay
what do all lakes and ponds have in common
are areas naturally filled with water -ponds are smaller than lakes
where is the littoral zone
nearest to the shore; waters are warm, shallow, and sunlit
where is limnetic zone
an open area too deep for emergent plants; is still warm and sunlit
where is the profundal zone
is cold and aphotic 2nd to bottom
what is photic
means sunlit
what is aphotic
means it is not sunlit
