Test 7 - The Solar System and Earth-Moon-Sun Interactions

Which planet has the shortest year?

• Earth

• Mercury

• Uranus

• Neptune

A layer of gas on a planet helps maintain a certain temperature. The temperature on Mercury ranges from about 430 °C during the day to about -170 °C at night. What is the best explanation for this?

• There is no liquid water on Mercury.

• Mercury is very close to the sun.

• Mercury has little to no atmosphere.

• Mercury has no plant life.

The chart below shows the average surface temperature or temperature range for each of the eight planets. What conclusions can be drawn from this information?

• Earth and the other inner planets have lower average surface temperatures than the other planets.

• Earth has the highest average surface temperature, and Uranus has the lowest average surface temperature.

• Earth and the other inner planets have higher average surface temperatures than the outer planets.

• Earth has the lowest average surface temperature, and Venus has the highest average surface temperature.

Galileo gathered evidence through observing Jupiter and Venus through telescopes that pointed towards a sun-centered solar system. What is the name of this sun-centered model of our solar system?

• Lunar model

• Heliocentric model

• Geocentric model

• Galaxy model

Which of the following best describes the orbit of the planets around the sun in the current model of the solar system?
