Possible causes of short-term climate changes can be explained by all of the following except

• earthquake activity

• reduction of solar energy because of interstellar dust (impact event)

• large volcanic eruptions

• burning of fossil fuels by humans

During the Pleistocene, Earth’s temperature was relatively static although it was cooler than today.

• True

• False

What is the main cause of the current ice age?

• Volcanic eruptions

• Milankovitch cycles

• Human activity

• Asteroid impacts

Plate tectonic activity is an important factor in global climate changes because atmospheric and oceanic circulation patterns may be greatly affected by the location of landmasses.

Volcanic activity may put sufficient particulate matter into the atmosphere to block incoming solar radiation, effectively causing short-term climate change.

• True

• False

There is little evidence to indicate that any warming has occurred within the human timespan, much less that any warming event is caused by human activity.

A geologist can recognize deposits made directly by a glacier, because the deposits tend to be poorly sorted with angular sediments.

• True

• False

The extinction of dinosaurs was important to the evolution of mammals because

• this opened many new habitats for mammals

• with less competition, mammals were able to diversify

• with new adaptive opportunities, mammals were greatly able to increase in numbers

• all of these are true
