name:____ date:__ period:____
directions: write either true or false before the number of the question or statement.
______1. the largest volcano in our solar system is on mars.
______2. mars has a very thin atmosphere compared to earth; therefore, its air pressure is greater than earth’s.
______3. the planet closest to the sun is mercury.
______4. the largest planet is saturn.
______5. the highest winds in the solar system are on neptune.
______6. earth’s moon can always be seen from any point on the earth.
______7. earth’s moon has many craters; they have not disappeared because there is no weather, thus, there is no erosion to erase the craters.
______8. venus is slightly larger than earth.
______9. the average temperature of venus barely fluctuates because of its incredibly thick atmosphere and high pressures. it has an average temperature well over 800 degrees fahrenheit during the day and night.
______10. jupiter, saturn, uranus and neptune are known as the four ‘gas giants.’
______11. rotation determines the length of day and night on a planet.
______12. the planet most famous for its rings of ice and dust is saturn.
______13. for most planets in our solar system, the sun rises in the east and sets in the west.
______14. the “gas giants” revolve (orbit) faster than the “terrestrials.”

Explanation:

1. Olympus Mons on Mars is the largest volcano in the solar - system, so it's True.
2. Mars has a thin atmosphere compared to Earth, and its air pressure is lower, so it's False.
3. Mercury is the closest planet to the Sun, so it's True.
4. Jupiter is the largest planet, not Saturn, so it's False.
5. The highest winds in the solar system are on Neptune, not Earth, so it's False.
6. The Moon is not always visible from any point on Earth due to the rotation and revolution, so it's False.
7. The Moon has many craters that remain because of lack of weather - related erosion, so it's True.
8. Venus is slightly smaller than Earth, so it's False.
9. Venus has a thick atmosphere and high pressure, resulting in little temperature fluctuation and high average temperature, so it's True.
10. Jupiter, Saturn, Uranus, and Neptune are known as the Gas Giants, so it's True.
11. Rotation determines day - night length on a planet, so it's True.
12. Saturn is famous for its ice and dust rings, so it's True.
13. On most planets, the Sun rises in the east and sets in the west (except for Venus and Uranus which have retrograde rotation), so it's True.
14. Gas Giants have longer orbital periods than Terrestrial planets, so they revolve slower, so it's False.
