Based on planetary orbits alone, which comparison is most likely correct?

• Mars is denser than Neptune

• Venus has a smaller tilt than Uranus

• Earth years are shorter than Saturn years

• Days on Jupiter are shorter than days on Mercury

Astronomers discover a new small, irregularly-shaped object in the solar system composed of frozen molecules of gases and other compounds. It is not orbiting a planet. How would it be classified?

• Satellite

• Comet

• Meteroid

• Dust

Which of the following statements best describes how the planets in our solar system formed?

• They formed from a nebular cloud of dust and gas.

• They are condensed rings of matter thrown off by a recently formed Sun.

• They are the remains of an exploded star once paired with the Sun.

• The Sun captured them from smaller, older, nearby star.

The four planets closest to the Sun are all made of dense, rocky material. Which of the following is TRUE?

• The similarity between these planets is caused by the Sun's gravity pulling heavier materials closer to the Sun during the formation of the solar system.

• The similarity between these planets is caused by the Sun's gravity pushing lighter materials further out during the formation of the solar system.

• The similarity between these planets is due to random chance.

• The similarity between these planets is caused by the Sun's heat, which burned off any lighter materials on these planets during the formation of the solar system.

Why is it relatively warm around the equator at all times of the year?

• The equator receives no rain at all times of the year.

• The equator receives no cloud cover at all times of the year.

• The equator receives indirect sunlight at all times of the year.

• The equator receives direct sunlight at all times of the year.

Which best explain the long summer days in Edinburgh?

• Earth is closer to the Sun in the summer, so more of the rays of the Sun reach Edinburgh.

• Edinburgh is tilted toward the Sun in the summer, so it is exposed to more sunlight.

• The rate of rotation of Earth changes as the seasons change, exposing Edinburgh to more sunlight.

• The location of Edinburgh near the Arctic Circle results in the city receiving direct sunlight in the summer.
