Tough Terrestrials
Order the terrestrial planets from closest to farthest from the Sun
Mercury, Venus, Earth, Mars!
Order the gas giants from closest to farthest from the Sun
Jupiter, Saturn, Uranus, Neptune
Fill in the blanks:
Gravity keeps the planets in ________ and inertia keeps the planets ___________.
Gravity keeps the planets in ORBIT and inertia keeps the planets MOVING!
Describe an asteroid
A small, irregularly shaped rocky object that orbits the sun
When is your test?
THURSDAY (for Cochran's class)
Who is Earth's Twin AND What is a major difference between this planet and Earth?
Venus and Venus is the hottest planet!
Which TWO gas giant have the most satellites?
Jupiter and Saturn
What do gravity and inertia help maintain in the solar system?
BALANCE
Where would you find most asteroids in our solar system?
Between Mars and Jupiter in the asteroid belt.
How can you EARN 5 bonus points (name 2 ways)?
Take the practice test until you earn a 90% of above.
Create notecards based on your study guide.
Which planet is rusty and dusty?
Mars
Order the gas giants from largest to smallest
Jupiter, Saturn, Uranus, Neptune
Use the white boards to sketch arrows to show how gravity and inertia impact the planets. Label the gravity arrow as G and the inertia arrow as I.
G arrow should be curved
I arrow should be straight
Describe a comet
A small body of ice, dust, and rock that follows a highly elliptical orbit around the sun.
The craters on Mercury are created by which of the following:
a. Comet
b. Meteor
c. Meteoroid
d. Meteorite
c. Meteoroid
Order the terrestrial planets from largest to smallest
Earth, Venus, Mars, Mercury
Uranus and Neptune and Methan gas in the atmosphere
Which planet has the strongest gravitational pull AND which planet has the weakest gravitational pull?
Strongest: Mercury
Weakest: Neptune
What is the difference between a meteor and a meteorite?
Meteor is burning/burned, enters Earth's atmosphere, creates a flash of light; meteorite is not burning/burned, is a rocky body.
Why can't a meteor create a crater on Earth?
A meteor is burned in Earth's atmosphere and will not reach Earth's surface.
Why does Merucry have so many craters AND how does this also explain why it's not the hottest planet?
No atmosphere! No protection from the meteoroids and comets. No atmosphere means the heat isn't trapped around the planet!
Provide 3 differences between terrestrial planets and gas giants
Terrestrial planets are more dense, closer to the sun, and have a rocky surface
Gas giants are less dense, larger, cooler, have rings and lack a rocky surface
Why does Mercury have the strongest gravitational pull and Neptune have the weakest?
Mercury is closest to the sun and Neptune is furthest from the sun.
A shooting star is actually a _________________.
A meteor
Name a Gas Giant that does not have rings.
You can't....they all have rings!
