The Water Cycle http://www.youtube.com/watch?v=Yw275056JtA

Zones of a Lake LITTORAL – the area near the shore, receives most amount of sunlight, high biodiversity. LIMENTIC – is open area away from the shore, most photosynthesis occurs here. BENTHIC - is the very bottom of the lake, organisms tolerate cooler temperatures, low levels of photosynthesis = low level of dissolved oxygen.

Zones of a Lake Diagram DO NOT NEED TO KNOW PROF-UNDAL

LOTIC VS. LENTIC LOTIC – MOVING WATER!!!!!! LENTIC – STILL WATER!!!!!!

POP QUIZ! Lotic or lentic??

THE ANSWER IS………… LOTIC!!!!!!!!!!!!!!!!!!

ANOTHER POP QUIZ! WHAT IS THE LOWEST LAYER OF THE LAKE ZONES?

ANSWER ISSSS….. BENTHIC!!!!!!!!!!!!!!!

Watersheds!!!

POP QUIZ YOU NEED TO KNOW THIS! WHICH IS LARGER, FIRST OR FOURTH ORDER?

FOURTH ORDER!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Ground Water Ground water starts at precipitation (aquifer) Is trapped underground until emerged from a spring or well

Riparian Buffer When you plant plants to help a water system Healthy Riparian Buffer : Vegetation is lush growing all along stream banks NO bare soil exposed in and around the stream Stream banks smooth sloping & gradual Trees & shrubs abundant within 100 feet
