Quizizz on Solar System Guided Notes

If you were to observe the Moon through a telescope, you would see many dark impact craters from meteoroids. The Moon is relatively close to the Earth and is also in the path of these meteoroids. Why is the Earth’s surface not covered by the same impact craters?

• The Earth has a thick atmosphere that protects it.

• The Moon’s gravity is greater than the Earth’s gravity.

• The Moon’s atmosphere is made of carbon dioxide, unlike ours.

• The Earth has an electromagnetic field to protect it from rocks.

The planets in our Solar System share some similarities, but their differences often outnumber the similarities. For example, one day on Neptune is only about 16.1 hours, and while Earth and Neptune both have natural satellites, Earth has only one moon, while Neptune has 13. Which of the following is also an accurate comparison of Earth and Neptune?

• Neptune has a more solid surface than Earth.

• Earth has a shorter period of revolution than Neptune.

• Neptune has a longer period of rotation than Earth.

• Earth has a lower average temperature than Neptune.

Teresa is studying the Solar System. She learns that Jupiter has 18 named moons as well as many small unnamed ones, and that Earth has just one moon. Which of the following best explains why Jupiter has so many more moons than Earth?

• 1. Jupiter is much farther away from the Sun than Earth, so it attracts more moons.

• Jupiter has a much greater mass, and therefore a greater gravitational pull, than Earth.

• Jupiter has a thicker, denser atmosphere than Earth, and it condenses rock particles to form moons.

• Jupiter is so much colder than Earth that clumps of ice form moons in its upper atmosphere more readily.
