- Q1What is the most important factor that determines Earth's temperature?Proximity or distance from the sunProximity or distance from the moonGas composition of the atmosphereThe amount of water on Earth45s
- Q2Earth is currently 150 million km away from the Sun. If Earth was 200 million km away from the Sun, it would no longer support life because-The temperature would be to coldthe oxygen would leave the atmospherethe surface water would evaporatethere would be less exposure to the solar wind45s
- Q3The layer of ozone in the upper atmosphere of Earth is important to life because it shields Earth from -TemperatureSolar WindsMeteorsUltraviolet Radiation45s
- Q4Which of the following characteristics of the planet, Earth, is essential to the survival of every living organism?The MoonThe Earths OrbitAbundance of WaterThe Earths Rotation45s
- Q5Which of the following characteristics of Jupiter best explains why Jupiter does not support life, while Earth does? Jupiter -Lack of WaterThe Moons of JupiterJupiter's RotationJupiter's Orbit45s
- Q6Which of the following characteristics of a planet will have the greatest influence on determining whether or not its temperature will be suitable to support life?The number of volcanoesThe gravitational forceThe rotation of the planetThe distance from the sun45s
- Q7Which of the following data could be collected about a planet in a distant planetary system, which might give scientists information about whether or not life exists on that planet?The number of other planets in our solar systemorbit of the planetRotation of the planetThe presence of an ozone layer45s
- Q8If Earth were much smaller than it is now, it would not support life because it would not have enough mass to -collect needed radiant energy from the Sun.The Earth would not have enough gravity to support an atmospheremaintain a gravitational pull on the Moon.rotate on its axis once per day.45s
- Q9Which of the following discoveries about Mars suggests conditions that may have once supported life? Mars has -The tallest mountain in our solar systemSmall amounts of water in the soiltwo moons orbiting the planetSmall atmosphere45s
- Q10All of the following characteristics of Jupiter's moon, Europa, are conditions that make it suitable for supporting life EXCEPT -Has an Atmospheresurface temperature of -260 F.Gravity on the surfaceWater on Surface45s
- Q11Earth's atmosphere contains water vapor and carbon dioxide. These greenhouse gases are important because they-Create the gravitational field of the earthtrap thermal energy in the atmosphere.Protect against magnetic particlesThey are what animals need to breath45s
- Q12A planet's ability to support life is partly determined by its orbit around the Sun, which is a result of the combination of the planet's momentum, and the Sun's -high temperaturesGravitational Pullgas compositionabsolute luminosity.45s
- Q13The ozone layer is degraded by certain chemicals that create holes in the ozone layer. If the presence of these chemicals significantly increases, it is reasonable to predict that organisms would -experience colder temperatures.run out of drinking water.be more exposed to ultraviolet radiation.have a difficult time breathing.45s
- Q14Scientists are constantly exploring the universe, looking for new planets that support life similar to the life on Earth. A new planet that supports life would be expected to have all of the following characteristics EXCEPT -Gaseous AtmosphereProtection from radiationan orbiting moon.Liquid Water45s
- Q15The Sun releases streams of charged particles called solar wind. What protects living organisms on Earth from the harmful effects of solar wind?High-level cloudsThe magnetosphereThe ozone layerOcean reflectivity45s
