CHAPTER 10

Terms in this set (19)

Is Europa in the Sun's habitable zone?
No
Venus's atmosphere has much more carbon dioxide than Earth's because ________.
Venus lacks oceans
In a runaway greenhouse effect, more water begins to evaporate from the oceans, which in turn ________.
increases the strength of the greenhouse effect, causing even more warming
Key evidence that Venus once had much more water than it does today comes from ________.
Venus's relatively high ratio of deuterium to ordinary hydrogen atoms
Based on all current evidence, if Venus had been born at Earth's distance from the Sun, then Venus today would probably ________.
have oceans and an atmosphere much like Earth
Which of the following is most likely to render our planet no longer habitable in the future?
A runaway greenhouse effect, between about 1 to 3 billion years from now
Scientifically speaking, which of the following ideas relevant to global warming is subject to the greatest uncertainty?
Predictions of future consequences of global warming
A carbon dioxide concentration of 400 parts per million (ppm) means that carbon dioxide represents ________ of Earth's atmosphere.
less than 0.1%
Suppose that Greenland's ice sheet was to melt completely. What effect would that have on sea level?
Sea level would rise many meters.
Earth has been gradually warming over the past few decades. Based on a great deal of evidence, scientists conclude that this warming is caused by _____.
human activities that are increasing the concentration of greenhouse gases in Earth's atmosphere
What is the definition of a star's habitable zone?
the range of distances from the star where liquid water can be stable on the surface of a suitable planet
Europa is located outside the Sun's habitable zone and yet may be habitable. How can this be?
Europa is tidally heated, allowing liquid water to exist beneath its icy surface
The Moon is in the habitable zone of the Sun at the same distance as the Earth but is not habitable. How can this be?
the Moon is too small to retain an atmosphere necessary for liquid water to be stable
If life is present on Venus today, it will most likely be
found in the atmosphere where highly acidic droplets of water can be found
Compared to today, in the future, the Sun's habitable zone will be
wider and farther from the Sun
The moist greenhouse effect refers to
the warming process by which water vapor rises into the upper atmosphere above the ozone layer where it is then broken apart by ultraviolet radiation
A star less luminous than our Sun will have a habitable zone that is
narrower and closer to the star than the habitable zone of the Sun
If the Earth were to be moved to where Venus is today,
the oceans would evaporate and carbonate rocks would decompose producing a runaway greenhouse effect much more severe than the one that exists on Venus today
As global warming continues, weather patterns will change causing
some parts of the Earth's landmass to become warmer while other parts will experience more extreme winters. The ocean temperatures will continue to rise
