Greenhouse effects in order, beginning with the Sun emitting radiation and ending in Earth's
surface experiencing an additional rise in temperature. correct answers 1. The sun emits radiation
2. Solar radiation penetrates the atmosphere
3. Earth's surface and greenhouse gases emit infrared radiation.
4. Greenhouse gases absorb infrared radiation released from the Earth system
5. Greenhouse gases re-emit infrared radiation released from the Earth system.
6. Some infrared radiation re-released from the greenhouse gases return to Earth's surface.
7. Earth's surface experiences a further temperature increase.
How does the human production of greenhouse gases contribute to global warming? correct
answers Human activities have lead to an increase in naturally occurring greenhouse gases and
manufactured fluorinated gases, such as chlorofluorocarbons, that trap infrared radiation.
Sequence of events in an El Niño-Southern Oscillation (ENSO) correct answers Initial stages of
the ENSO
1. Air pressure are low in the Western Pacific and high in the Eastern Pacific
2. Equatorial winds push warm water from east to west
3. Warm water moves towards South America
4. Cold-water upwelling halts along the South American coasts .
5. South American coastlines fisheries become less productive
6. Increased precipitation occurs in South America
Factors contributing to the motion of ocean gyres correct answers -differences in ocean surface
temperatures
-the direction of predominant winds
-effect of Earth's rotation on water and wind
How is ice melting the Arctic Ocean predicted to affect the climate of Europe? correct answers
The influx of cold water disrupt ocean currents that circulate warm water around Europe, cooling
overall temperatures.
Why a coastal mountain range has different climates on the windward (wind-facing) and leeward
(wind-sheltered) sides. correct answers Ocean winds become cooler as they travel up the
windward slope, causing water vapors to condense as rain. The air is dry when it reaches peak
elevations and it becomes warmer as it descends the leeward slope.
Why do distantly related species of plants in different parts of the world often assume similar
growth forms when they experience similar climates? correct answers Similar selections
pressures cause convergent evolution of species in separate lineages.
