How does a tornado form?


How does humidity change in regards to temperature?


Why does condensation forms on the outside of a cold water bottle?


http://www.education.noaa.gov/Freshwater/Water_Cycle.html


What are some of the greatest challenges associated with our water supply?

EnvironSci book p.293 - 298


What are some of the greatest challenges associated with our water supply?

  • Access to Groundwater (Aquifers are recharged by Surface water)

  • Transpiration (Cottonwood & Willow trees suck up and evaporate water)

  • Competition for Use of water supply (agriculture, drinking water, septic system)

  • Agriculture Nitrates & Phosphorous (from fertilizers)

  • Urbanization (population growth in cities draws more groundwater)


Use a diagram to show the important role that Aquifers play in our water supply

Where does the majority of YOUR drinking water come from?


Where is the majority of the freshwater on earth found?


Where is your drinkingwater?


http://www.education.noaa.gov/Freshwater/Water_Cycle.html


Icebergs: Freshwater or Saltwater?


When WATER becomes as valuable as OIL, where would you live? And why?

http://www.technologijos.lt/n/mokslas/gamta_ir_biologija/S-31667/straipsnis/Vanduo-poreikiai-ir-istekliai?l=2&p=1


Where are the biggest reservoirs of freshwater on Earth?


What causes precipitation to occur?


Explain what happened in the bottle.

  • Demo 1: “Cloud in a bottle” demo (with bicycle tire pump)

  • Demo 2: “Cloud in a bottle” demo (match cloud seeding)

What process is this?


What patterns can you identify?

What factors do you think influences these precipitation patterns

Where would you place

your Farm-ville?

Describe one method that may help us obtain more drinking water

Topography (terrain) Rain


Rain Shadow Effect

  • Study the Hawaiian Island terrain maps with your group.

    • http://www.wrcc.dri.edu/precip.html

  • Then study the Avg Precipitation maps over the islands.

    • Q. What patterns can you identify in regards to precipitation and terrain?


Rain Shadow Effect


What is humidity?

The Gulf Stream

What solutions do scientists think may solve our shortage of drinking water?


Cloud Seeding


What process is this?


Transpiration


What is happening in this picture?

Why would someone attempt to do this?


Describe one solution scientists think may solve our shortage of potable water


What are the problems associated with privatizing potable water?


Blue Gold


What are some sustainable practices that you can adopt to save our potable water?


What are the issues that arise when we interfere with the movement of our groundwater?


What are the effects of El Nino?


El Nino

  • Where does the name “El Nino” come from?


Normal Pacific Ocean Currents

But every 4 - 12 years…


El Nino Pacific Ocean Currents


  • Is this a normal year? …or an El Nino year

http://scienceofdoom.com/2010/08/25/clouds-and-water-vapor-part-two/


Indonesia

Normal rain

South America

Normal rain


Indonesia

Drought!

South America

INTENSE Rain!


Ocean Nutrient upwelling

In terms of Nutrients, what does Ocean upwelling do off the coast of South America?


Ocean Nutrient upwelling

How does an El Nino year affect Nutrient cycling in off the coast of South America?


Normal

El Nino

La Nina

How do we collect this data?

http://www.pmel.noaa.gov/tao/jsdisplay/


What does normal climate look like around the Pacific?

Purple = precipitation

Red = surface temperature

Blue = nutrient Upwelling


What does climate look like during an El Nino year?

Purple = precipitation

Red = surface temperature

Blue = nutrient Upwelling


How does El Nino affect precipitation patterns, ocean temperatures, and nutrient upwelling?


How does El Nino differ from La Nina?


What does climate look like during a La Nina year?

Purple = precipitation

Red = surface temperature

Blue = nutrient Upwelling


How does a La Nina year affect farmers in South America and Indonesia?
