Meteorite

Question 5

A small, icy body that orbits the Sun

Answer 5

Comet

Question 6

Planets that have a rocky crust and dense mantles and cores

Answer 6

Terrestrial Planets (inner solar system)

Question 7

Planets made mostly of hydrogen, helium, and other gases

Answer 7

Gas giants (outer solar system)

Question 8

Process of change in crust due to the movement of hot material underneath the surface

Answer 8

Tectonics

Question 9

Process where molten rock moves from a planets interior to the surface

Answer 9

Volcanism

Question 10

Small, solid, rocky body that orbits close to the sun

Answer 10

Asteroid

Question 11

List the planets in order starting closest to the sun. Label which are inner and outer planets, and which are terrestrial and gas giants.

Answer 11

Mercury, Venus, Earth, Mars-inner, terrestrial

Jupiter, Saturn, Uranus, Neptune-outer, gas giants

Question 12

How did the solar system form?

Answer 12

From a cloud of gas and dust, the gas and dust stuck together in clumps forming the planets, moons, and other space bodies

Question 13

What is impact cratering? How are craters formed?

Answer 13

A small space object hits a planets surface, making a big hole in the ground called a crater

Question 14

How do the distances between the inner planets compare to the distances between the outer planets?

Answer 14

The inner planets are closer together, and the outer planets are more spread apart.

Question 15

Which planets show evidence of tectonics?

Answer 15

Terrestrial planets

Question 16

Which planets have volcanoes?

Answer 16

Terrestrial planets

Question 17

What are the white bands on Jupiter made of?

Answer 17

Clouds

Question 18

What are the rings around the gas giants made of?

Answer 18

Small particles

Question 19

Are the asteroids, planets, and comets orbiting in the same plane or different planes?

Answer 19

Same plane

Question 20

Do the gas giants have any of the 4 processes?

Answer 20

No

Question 21

How is a moon different from a planet?

Answer 21

A moon is smaller and a moon orbits a planet, instead of orbiting the Sun

Question 22

What are the 4 processes? Describe each one.

Answer 22

Tectonics-hot mantle moves crust, volcanism-molten rock moves from the interior to the surface, impact cratering-space objects leave craters when they hit a planets surface, weathering/erosion-rock breaks down

Question 23

Why is a comet sometimes bright?

Answer 23

Sunlight shines on them

Question 24

What object is between Mars and Jupiter?

Answer 24

Asteroid belt

Question 25

Describe the atmosphere of Mars.

Answer 25

Thin, causes weathering and erosion

Question 26

Why is a meteor visible?

Answer 26

Because it is a brief streak of light that glows

Question 27

What are Jupiter and Saturn mostly made of? What about Uranus and Neptune?

Answer 27

Jupiter and Saturn-hydrogen and helium

Uranus and Neptune-methane and ammonia

Question 28

True or false: Gas giants have a deep atmospheres.

Answer 28

True

Question 29

True or false: Planetary rings are made mostly of gases.

Answer 29

False, they are made of small particles.

Question 30

True or false: clouds form the white stripes and patches on gas giants.

Answer 30

True

Question 31

True or false: All planets have rings.

Answer 31

False, only the gas giants have rings.

Question 32

True or false: None of the terrestrial planets have moons.

Answer 32

False, Mercury and Venus are the only planets that don’t have moons.

Question 33

True or false: The inner planets are farther apart than the outer planets.

Answer 33

False, the outer planets are farther apart than the inner planets.

Question 34

True or false: A comet is bright because it burns up in Earths atmosphere.

Answer 34

False, a comet is bright because sunlight shines on it.
