Last Name, First Name *

Period (Number Only) *

Why is ozone in the stratosphere a good thing, but ozone in the troposphere is a bad thing? What can ozone do to the human body? *

What pH (power of Hydrogen) in a sample of rain water would be indicative of acid rain in the Northeastern United States? *

Name and describe some common effects of acid rain. *

Summarize some common air pollutants, their major sources, and their effects on human health. You should have at least six pollutants listed. *

SMOG is made worse by *

an inversion layer in the troposphere

automobile exhaust

solar radiation

all of the above

only 1 and 2 above

Which of the following does depletion of ozone in the stratosphere by chlorofluorocarbon emissions NOT affect? *

cataracts

skin cancer

weakening of immune system

death to phytoplankton in oceans

warming of the planet on a grand scale

The ozone hole is an area of lowest ozone concentration that mainly exists over what continent? *

North America

Europe

South America

Asia

Antarctica

Look at the graph of Antarctic Temperatures for the past 420,000 years seen on page 474. What has happened to world wide temperatures throughout this time? How would a graph of carbon dioxide in the atmosphere look if we superimposed that over the graph of temperature? *

Summarize how Milankovitch Cycles seen under the heading of Earth's Motions have caused changes to Earth's climate. *

Evidence exists that shows that glaciers once covered places like India that are now on the Equator. What could explain these observations? *

Earth is likely to be warmer when *

there are greater numbers of sunspots on the Sun

there are fewer numbers of sunspots on the Sun

there are more volcanic eruptions of sulfur dioxide

Earth is farther from the Sun

Volcanic eruptions can cause both warming and cooling of Earth's climate. How could this be the case? Explain. *

Anthropogenic (human induced) causes of climate change have been widely discussed lately in the media, scientific community, and in political arenas. Give three examples of human activities that are leading to anthropogenic climate change. *

Shells of marine species in sea floor sediments are analyzed and higher levels of heavy oxygen 18 are found. This means that the climate during that period was *

warmer, as more heavy oxygen was stored in the oceans

cooler, as more heavy oxygen was stored in the oceans

warmer, as less heavy oxygen was stored in the oceans

cooler, as less heavy oxygen was stored in the oceans

Glacial ice cores are analyzed and higher levels of heavy oxygen 18 are found. This means that the climate during that period was *

warmer, as more heavy oxygen was stored in the oceans

cooler, as more heavy oxygen was stored in the oceans

warmer, as less heavy oxygen was stored in the oceans

cooler, as less heavy oxygen was stored in the oceans

Wetter and cooler years in climate records are indicated by *

thicker tree growth rings

thinner tree growth rings

the same sized tree growth rings

tree growth rings cannot be used to gauge past climates
