Heat Capacity

1) Which of the following contains the greatest number of carcinogens?

A) a thick vanilla milkshake

B) a Twinkie snack

C) chewing tobacco

D) tap water from most cities in the United States

2) You examine an ice core sample from 10,000 years ago when global temperatures were

 unusually high. Based upon past studies and insights from current GHG levels, we expect that

 atmospheric levels of carbon dioxide:

A) and methane were unusually low.

B) and methane were unusually high.

C) were high but methane levels were low.

D) were low but methane levels were high.

3) In his movie, An Inconvenient Truth, Al Gore warns of increasing levels of carbon dioxide in

 the atmosphere which suggest that:

A) methane levels will soon rise, destroying the ozone layer.

B) global temperatures will also continue to rise.

C) the oceans of the world are losing carbon dioxide.

D) clouds are thinning and global precipitation is declining.

4) Evidence from proxies indicate eight major oscillations in global temperatures over the past

 800,000 years, most likely the result of:

A) rising and falling sea levels that greatly impact photosynthetic activity.

B) variations in solar activity that produce different levels of radiation.

C) Milankovitch cycles of periodic variations in Earth’s orbits around the sun.

D) lunar cycles in which the moon orbits at different distances from the Earth.

5) In general, temperatures along an ocean coastline vary less than temperatures 100 miles

 inland. This moderation of temperatures along coastlines is because:

A) as the oceans evaporate it cools off the coastlines.

B) the sun shines more intensely away from the ocean coastlines.

C) ocean temperatures change more quickly than air temperatures.

D) they have an innate heat capacity.
