- BThe Earth's surface temperature would be warmer than it is today
- CThe Earth's surface temperature would be the same temperature as it is today.
- DThere is not enough information to answer this question.
4Earth started with about as much carbon as Venus has. In Venus, the carbon is mainly in the atmosphere. Where is it on Earth?
- AIt was lost when the primary atmosphere escaped.
- BIt is in rocks, the ocean, and in life.
- CIt evaporated from the Earth's atmosphere while other gases were retained.
5What started the runaway icehouse effect on Mars?
- AThe Sun becoming dimmer over time
- BLeaving the door open when the air conditioner is on
- CVolcanic eruptions stopped as Mars cooled
- DGlacier movement
6Earth has roughly ___________ times more atmospheric pressure than Mars and __________ times less than Venus.
- A2,000; 2
- B10; 10
- C2;10
- D200; 100
- E1,000; 200
7Runaway convection in the Earth's atmosphere can lead to:
- AViolent storms
- BSnow
- CAurorae
- DAcid rain
- EDestruction of ozone
8Given the thickness and chemical composition of Venus's atmosphere, by how much would you expect its average surface temperature to change between day and night?
- Aby tens of K (like Earth)
- BThere should be almost no change in temperature.
- CThe answer depends on where Venus is in its orbit around the sun.
- Dby hundreds of L (like Mercury)
9The shape of the Earth's magnetosphere is modified by:
- AThe Moon's today force
- BEarth's own gravity
- CThe solar wind
- DEarth's elliptical orbit
- EAsymmetric in the shape of Earth's core
10The main greenhouse gases in the atmosphere of the terrestrial planets are:
- AHydrogen and helium
- Boxygen and nitrogen
- Cmethane and ozone
- Dmethane and ammonia
- Ecarbon dioxide and water vapor
11Earth releases the energy it receives from the Sun by emitting ____________ radiation.
- AVisible
- BInfrared
- CUltraviolet
- DRadio
- EMicrowave
12Heating from _________ causes the top of the Earth's stratosphere to be warmer than the bottom.
- Athe ozone layer absorbing UV light
- Bconvection
- Cthe greenhouse effect
- Dhigher-energy particles in the solar wind
- Echarged particles trapped by magnetic fields
13If water vapor were released from Venus's surface due to tectonic activity into its upper atmosphere, what would most likely happen to it?
- AIt would rise into the atmosphere and form hurricane-like storms.
- BThe water vapor would relieve the greenhouse effect and decrease Venus's surface temperature.
- CWater droplets would condense into rain and form lakes on Venus's surface.
- DUV light would break apart the water molecules, and the hydrogen would be lost into space.
- EThe water vapor would chemically react with carbon dioxide and form acid rain.
14Like Mars and Venus, Earth originally had a significant amount of carbon dioxide in its atmosphere. Where is the majority of the carbon now?
- AIt has escaped into outer space.
- BIt is bound up in rocks.
- CIt is bound up in the plant life on Earth.
- DIt is dissolved into the oceans.
- EIt it still in the atmosphere in the form of complex molecules.
15Based solely on mass and distance form the Sun, which of the following terrestrial planets would you expect to retain the densest secondary atmosphere?
- AMercury
- BThe Moon
- CVenus
- DEarth
- EMars
16What is the main reason Hadley circulation in a planet's atmosphere breaks up into zonal winds?
- Aa planet's rapid rotation
- Bconvection driven by solar heating
- Cheating from the solar wind
- Dheating from the greenhouse effect
- Ehurricanes developing along the planet's equator
17The presence of gases like carbon dioxide and water vapor in a planet's atmosphere is direct evidence of __________ in a planet's history.
- Acometary impacts
- Bhigh surface temperatures
- Ca lack of asteroid impacts
- Dvolcanic activity
- Ethe greenhouse effect
18All weather and wind on Earth are a result of convention in the:
- Athermosphere
- Bmesosphere
- Cionosphere
- Dstratosphere
- Etroposphere
19In the absence of the greenhouse effect, the water on the surface of the Earth would:
- Abe absorbed into rocks

- Cfreeze
- Dreamin in liquid form
- Eescape into outer space
20____________ in our atmosphere is a direct consequence of the emergence of life.
- ACaron dioxide
- BWater vapor
- CNitrogen
- DOxygen
- EHelium
21Why did the territorial planets lose the majority of the gas in their primary atmospheres?
- AThe solar wind was too strong and blew these gasses off the planets.
- BThey were too hot and their escape velocities too low to hold onto them.
- CTheir high surface temperatures made the gas chemically react with the rock.
- DThe initial gases were so heavy when the planet differentiated that they sank to the core.
- EThe centrifugal force from the planet's fast rotation rates made them fly off.
22The amount of carbon dioxide in the Earth's atmosphere has been increasing over the last 50 years because of:
- Aglobal warming
- Bthe burning of fossil fuels
- Cthe growth of the ozone hole
- Dincreased energy output form the Sun
