1 Question 1 Which of the following are terrestrial planets? 1)only Earth 2)the Earth, Moon, and Venus 3)Mercury, Venus, Earth, and Mars 4)Mercury, Venus, Earth, Moon, and Mars 5)Mercury, Venus, Earth, Moon, Mars, and Ceres

2 Question 1 Which of the following are terrestrial planets? 1)only Earth 2)the Earth, Moon, and Venus 3)Mercury, Venus, Earth, and Mars 4)Mercury, Venus, Earth, Moon, and Mars 5)Mercury, Venus, Earth, Moon, Mars, and Ceres Terrestrial planets are rocky.

3 Question 2 The major difference(s) between the terrestrial and jovian planets involve(s) 1) mass. 2) density. 3) rotation speed. 4) density and rotation speed. 5) mass and density.

4 Question 2 The major difference(s) between the terrestrial and jovian planets involve(s) 1) mass. 2) density. 3) rotation speed. 4) density and rotation speed. 5) mass and density. Jovian planets are more massive, but less dense, than terrestrial planets.

5 Question 3 Which of the following defines density? 1) mass times surface gravity 2) mass divided by volume 3) size divided by weight 4) mass times surface area 5) weight divided by size

6 Question 3 Which of the following defines density? 1) mass times surface gravity 2) mass divided by volume 3) size divided by weight 4) mass times surface area 5) weight divided by size Density can be thought of as MATTER / THE SPACE IT OCCUPIES Lots of matter in a small space = HIGH density Little matter in a large space = LOW density

7 Question 4 Compared with terrestrial planets, jovian planets share all of the following characteristics except 1) low density. 2) large size. 3) many moons. 4) ring systems. 5) slower rotation.

9 Question 5 Asteroids are evidence of 1) a planet that once orbited the Sun but later was destroyed. 2) ancient material from the formation of the solar system. 3) a collision between Jupiter and one of its larger moons. 4) comets that were trapped by Jupiter’s gravitational field.

10 Question 5 Asteroids are evidence of 1) a planet that once orbited the Sun but later was destroyed. 2) ancient material from the formation of the solar system. 3) a collision between Jupiter and one of its larger moons. 4) comets that were trapped by Jupiter’s gravitational field. Asteroids, Meteoroids, and Comets may have not changed at all since the solar system formed.

11 Question 6 The condensation theory explains why 1) our planet Earth has water and rain. 2) stars are more likely to form large planets orbiting very near. 3) terrestrial planets are different from jovian planets. 4) the Moon formed near the Earth. 5) Pluto has such a circular orbit.

12 Question 6 The condensation theory explains why 1) our planet Earth has water and rain. 2) stars are more likely to form large planets orbiting very near. 3) terrestrial planets are different from jovian planets. 4) the Moon formed near to Earth. 5) Pluto has such a circular orbit. The condensation theory explains how the temperature of the early solar nebula controls which materials are solid, and which are gaseous.

13 Question 7 Any theory of the origin of the Solar System must explain all of these EXCEPT 1) the orbits of the planets are nearly circular, and in the same plane. 2) the direction that planets orbit the Sun is opposite to the Sun’s spin. 3) the terrestrial planets have higher density and lower mass. 4) comets do not necessarily orbit in the plane of the solar system.

The planets do orbit in the same direction that the Sun spins. Most also spin in that direction, and most also have large moons that orbit in that direction.
