Give an example of a cultural ecosystem service.

recreation (hiking, swimming, safari tour)

100

What types of surfaces cause an increase in runoff?

Impermeable; urban areas; pavement, concrete, etc

100

What soil texture has the best drainage?

sand

100

How can mining impact groundwater negatively?

leaching of chemicals from discarded spoils, removal of trees leads to less; shafts provide unfiltered path for water.

100

Where does all weather on Earth take place?

troposphere (below tropopause)

200

What explains/causes seasons, wind motion, and ocean currents?

solar radiation 

200

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

200

What type of boundary has subduction?

Convergent (o-c; o-o)

200

What could we do to reduce runoff in urban areas?

permeable pavement, more grass spaces, greenrooves

200

Which layer contains a high concentration of ozone (O3)

stratosphere

300

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

300

What current explains the humid, wet Southeast US conditions? 

Gulf Stream (warm ocean current)

300

What forms mountains?

Convergence (volcanoes or continental collisions)

300

What is an example of a tragedy of commons experienced in the ocean?

overfishing, ocean acidification, nonpoint pollution (runoff)

300

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)

400

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.

400

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)

400

Using your soil triangle (notes): what is the texture if the soil is 25% clay, 20% silt, and 55% sand?

sandy clay loam

400

What are the 2 most impactful nutrients when considering chemical water quality from runoff?

Nitrogen and phosphorus

400
What explains the drier-than-average (for latitude) conditions on the eastern side of the Cascade Mountain range?

rain shadow effect

500
Where can you find active volcanoes NOT on a plate boundary?

Hot spot (hawaii)

500

Overpumping can lead to irreparable failure of a well in coastal areas due to...

Salt water intrusion into groundwater aquifer.

500

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) 

500
What can increase soil drainage?

adding sand, humus, manure, or companion crop
