New material• Wetlands three types:• 1. Freshwater bogs

New material• Freshwater bogs formation

New material• Wetlands three types:• 2. Freshwater marsh

New Material• Wetlands three types:• 3. Freshwater swamp

• Explain the purpose of wetlands?• Limnetic Zone – sunlight penetrates, great deal of life

and photosynthesis • Profundal zone – Darker (but not pitch black) where

sunlight cannot get through. Little plant life here, plants would have to reach up through to the Limnetic Zone to survive

• Benthic zone – bottom of the pond / lake. Feels silty from decomposing leaves, sticks,… high nutrient, but low O2

New Material

Zone of the pond / lake

• Discuss and define the following with the use of your notes as a table:

• Water table• Artesian Well• Unconfined Aquifer• Ogallala Aquifer (where is it located?)• Impact of available water due to Global Climate
