Which 2 of the following species provide indirect services to humans? (Check 2)

• Bees, their pollination contributes to food production.

• Bats, they eat harmful mosquitoes.

• Perwinkles, they contain chemicals that we use to fight cancer.

• Mangroves, they block storm waves from causing erosion.

Which of the following is NOT an example of an aesthetic service?

• Oysters filtering the water.

• Green-spaces having calming psychological effects on humans.

• Environmental stewardship being passed from one generation to the next.

• The beauty of biodiversity and it's impact on all generations.

Which of the following best describe Proxy Data?

• Direct measurements that show general, not specific, patterns.

• Indirect measurements such as computers, taken of current situations, that show precise data.

• Data that can easily be gathered and shared between networks by proxy internet servers.

• Natural recorders of history that can be analyzed to reconstruct historical climate.

Which of the following is the best example of instrumental data?

• using a thermometer to check the air temperature.

• measuring the amount of rust on ancient metallic rocks.

• measuring the thickness of growth between tree rings.

• testing the amount of magnesium in a sea-shell.

Which of the following proxy records can *best* indicate the rate of glacial melt and water discharge from the glaciers?

• the shell of N. Pachyderma

• the color of tree rings

• varves (sediment)

• coral growth rings

Which of the following best describes the data collection from ice core logs?

• drilling can only occur in newly formed glaciers, they will show all 4 seasons and contain CH4 methane. The ice is boiled and analyzed under a microscope.

• drilling occurs in areas that do not currently have glaciers. They remove ice from the continental crust, it is re-frozen at the lab to measure how the atoms reorient themselves.

• drilling occurs in areas that have year-round glaciers. Small pieces of ice are removed, crushed, and the gas bubbles are trapped and analyzed for CO2.

• digging is done by hand, the ice is very fragile. The entire log is kept frozen, only one person can examine the specimen at a time. The dark sections represent summer, and we can see how long summer lasted.

How are seasons analyzed in ice core logs?

• There are 2 seasons visible, Winter and Summer, the lighter layer formed in Summer because they have more trapped air bubbles.

• All 4 season can be seen, but fall stands out because the amount of pollen creates a thin yellow layers within the ice core.

• Only Winter can be seen, the lighter shades show whether there was a lot of snow, or a small amount of snow

• Only Summer can be seen, the darker shades show if there were extended periods of rain or if it was arid (dry) conditions.
