Homework
• Read pages 401 to 402 stopping at Freshwater Systems. After reading we will discuss it.

• Could it lead to a situation such as what happened to the Aral Sea?
New Material
What are these pictures of? How and why did this happen?
• The amount of water available on the planet.
New Material
• Water moves by traveling through the course of least resistance. Often forming things such as an oxbow.
New Material
• Is this picture below real?• What is the negative impact of building a dam for
hydroelectric power?• Why was Hurricane Katrina so devastating?
At your tables, discuss the following topics:
• What is the negative impact of building a dam for hydroelectric power?
• Prevents water from carrying nutrients down stream. Also, re-directs water at the cost of the ecosystem

New Material
• Floodplain – New Material
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
Change
