AIM: SWBAT Describe the hydrological cycle and cite a good example of how humans have
disrupted itPlease Do Now: 1) Why are there more sardines
than sharks in an ecosystem?2) Why are the hydrological cycle, and other
biogeochemical cycles, examples of closed systems?

Hydrological CycleThere is a
finite amount of water on the planet

How do living things influence the hydrological cycle?EvaporationWhen the water molecules
absorb the sun’s energy, they go from a liquid state to a gaseous state
BIOLOGICAL INPUT: transpiration, the process by which plants take water up from the soil and it evaporates through its leaves, drastically increases the amount of evaporation happening on land

How do living things influence the hydrological cycle?CondensationWhen water vapor reaches
a high enough part of the atmosphere, it cools down to a point where it is tiny drops of liquid again
BIOLOGICAL INPUT: often water droplets will not condense unless there is a little grain of pollen or a microbe floating in the air for it to start forming around

PrecipitationWhen the water
droplets in the clouds have gotten too big, they fall to earth as rain or snow

What happens to water on the ground?A number of things happens to recently
precipitated water:Gets tied up in a glacier or snow capWill run off into a lake or an oceanWill enter the soil, become part of the ground
water, called infiltrationOr it can enter the biosphere and become
part of the tissue of living organisms

What are Aquifers?Aquifers are underground
reservoirs of waterThey are the result of
infiltrationThey take an extremely
long time to fill upWe are pumping the
water out of them way faster than the hydrological cycle can replenish it
Ex: ogallala aquifer, central valley of california

Subsistence from aquifer depletion

Why Does the Hydrological Cycle Matter?The two abiotic factors that are most
important in determining what can live in an environment are temperature and how much precipitation the area gets

“Quiz” timeWhat you are going to do for your quiz grade
this week is use the dichotomous key I have prepared and determine the identity of an unknown leaf species
It will be good practice for next week outdoors
Should be an easy 100%All you need to do is write down all the steps
you took through the key to arrive at your answerEx: question 1: no, question 2: no, question 4:
yes, chart 8: northern red oak
