- 9.Ice cores recovered in Greenland and Antarctica provide a record of changes in atmospheric temperature and compositon dating back to over 100,000 years ago. Based on ice core data, which of the following statements is TRUE?
- A.
Ice cores indicate that global temperatures have been fairly constant over the last few tens of thousands of years.
- B.
The atmospheric concentration of greenhouse gases such as carbon dioxide and methane have actually decreased over the last 50 years.
- C.
Atmospheric temperature has been steadily increasing over the last 12 thousand years and we are presently in an interglacial cycle
- D.
The concentrations of atmospheric greenhouse gases increase dramatically during periods of glaciation and global cooling.
- 10.How can sunspot activity possibly affect Earth's climate?
- A.
Higher sunspot activity increases the solar wind, which in turn warms Earth's upper atmosphere
- B.
Lower sunspot activity allows more solar radiation to escape the Sun and reach Earth, thus warming the planet
- C.
Higher sunspot activity pushes Earth's orbit further from the sun, thus cooling the planet
- D.
The amount of sunspot activity never changes and therefore cannot affect Earth's climate
- 11.Changes in the angle of tilt of Earth's rotational axis occurs approximately in ____
- A.
1
- B.
26,000
- C.
41,000
- D.
100,000
- 12.Which of the following examples will result in positive feedback?
- A.
Greater snow cover during climatic cooling reduces the activity of carbon dioxide sinks such as photosynthesis and formation of carbonate rocks, thus causing carbon dioxide to build up in the atmosphere
- B.
Warming of the climate increases evaporation in the oceans, leading to greater cloud cover such that more solar radiation is reflected back into space.
- C.
An increase in plant activity during global warming results in more carbon dioxide being removed from the atmosphere
- D.
Climate cooling increases the snow cover on land, thus increasing global albedo and causing more solar radiation to be reflected back into space
- 13.How did global climate overall change throughout the last 60 million years of the Cenozoic Era?
- A.
Global climate was cold throughout the entire Cenozoic Era as evidenced by 60 million year old glaciers found today in Antarctica
- B.
Cenozoic climate was warmest 60 million years ago and has gradually cooled since then, culminating in the Pleistocene Ice Age beginning 2 million years ago
- C.
Global climate today is the warmest it has ever been over the last 60 million years
