Potluck
Give an example of a cultural ecosystem service.
recreation (hiking, swimming, safari tour)
What types of surfaces cause an increase in runoff?
Impermeable; urban areas; pavement, concrete, etc
What soil texture has the best drainage?
sand
How can mining impact groundwater negatively?
leaching of chemicals from discarded spoils, removal of trees leads to less; shafts provide unfiltered path for water.
Where does all weather on Earth take place?
troposphere (below tropopause)
What explains/causes seasons, wind motion, and ocean currents?
solar radiation
Where does La Nina form and what happens to sea surface temps?
Tropical East Pacific (off coast or Peru) & cooler than normal (extra wind) more fish
What type of boundary has subduction?
Convergent (o-c; o-o)
What could we do to reduce runoff in urban areas?
permeable pavement, more grass spaces, greenrooves
Which layer contains a high concentration of ozone (O3)
stratosphere
The beginning of which season has the shortest day of the year (the fewest daylight hours)?
Winter (NP pointed away from the sun) winter solstice
What current explains the humid, wet Southeast US conditions?
Gulf Stream (warm ocean current)
What forms mountains?
Convergence (volcanoes or continental collisions)
What is an example of a tragedy of commons experienced in the ocean?
overfishing, ocean acidification, nonpoint pollution (runoff)
What explains the presence of deserts at 30* Latitude?
Horse latitudes where sinking air creates high-pressure systems & clear skies (no rain)
-additionally: sinking air heats (compresses) and dries out (bonus for that part)
How could extreme climates (very hot or cold) explain a larger ecological footprint?
Need to use more energy to heat or cool more times of the year.
If you remove trees from the shoreline of river, what would happen to the temperature and dissolved oxygen?
temp increases; DO decreases (warmer water & more runoff cause dead zones)
Using your soil triangle (notes): what is the texture if the soil is 25% clay, 20% silt, and 55% sand?
sandy clay loam
What are the 2 most impactful nutrients when considering chemical water quality from runoff?
Nitrogen and phosphorus
rain shadow effect
Hot spot (hawaii)
Overpumping can lead to irreparable failure of a well in coastal areas due to...
Salt water intrusion into groundwater aquifer.
Where do most earthquakes occur?
Pacific plate boundaries
Plate boundary will be accepted if no other team answers (or no loss of points if next team says pacific plate)
adding sand, humus, manure, or companion crop
What season would we experience in N Hemisphere at the bottom of the diagram (front)?
fall
