Answers
1
A planets day is calculated by
Distance from the sun
Rotation
Color
Revolution
2
What keeps objects in orbit?
Gravity
Revolution
Rotation
Friction
3
Why do gas giants have more moons?
More Mass = More Gravitational pull
Less Mass = More Gravitational pull
They are further from the sun
They are closer to the sun
4
A planet's year is calculated by a planets
Revolution
Length of Orbit
Diameter
Rotation
5
Why does Uranus take longer to orbit than earth?
Earth is smaller
Uranus is Closer to the sun
Uranus is Further from the sun
Uranus is larger
6
What went to mars to explore?
Rovers
cyborgs
spacecraft
Wall-E
7
Which is true?
as distance decreases, gravity remains constant
as distance decreases, gravity decreases
as distance increases, gravity increases
as distance increases, gravity decreases
8
Inner planets are also known as
Gas planets
Big Planets
Terrestrial Planets
Rocky Planets
9
What did we send to mars?
A letter
Human
Rover
Monkey
10
What planets are less dense?
Outer planets, because they are made of gas
inner planets, becuase they are made of rock
11
Why would a planets day be shorter?
Slower Spin (rotation)
Larger Orbit (revolution)
Faster spin (rotation)
smaller Orbit (revolution)
12
Which is true?
as mass increases, gravity decreases
as mass decreases, gravity remains constant
as mass increases, gravity increases
as mass decreases, gravity increases
13
What law is this? Every particle attracts every other particle in the universe with a force which is directly proportion
Newton's 1st law
Newton's 2nd Law
Law of universal Gravitation
14
Why do gas planets tend to have more moons?
They have more gravity
they have less gravity
their solid surface causes more density
they have a large magnetic hemogination field
15
Which planet is hottest at it's surface?
Venus
Pluto
Mercury
Mars
16
Why does the moon appear to move across the sky?
Earth's Rotation
Earths Revolution
17
What properties of the planets did we compare?
Size
chemical makeup
Temperature
surface features
18
What separates the inner planets from the outer planets?
Kuiper Belt
Asteroid Belt
Meteoroid
Comet Belt
19
Why would you weigh more on Earth than on Venus?
Venus is smaller more gravitational pull
Earth is larger = More gravitational pull
Venus is closer to the sun
Earth is further from the sun
20

made of rock, far from the sun
Made of gas, have rings
made of gas, close to the sun
Made of gas, extremely small
21

Venus, Earth, Mars, Jupiter
Mercury, Venus, Earth Mars
25
Why would we send an unmanned craft before sending a manned one?
Distance
Just because
Its more interesting
Safety
