100
How long ago was it when our solar system was created?
What is "4.6 billion years ago."
100
Three objects we can find in our Solar System besides planets and a star.
What is "Meteroid, Asteroid, and Comet and dwarf planets, moons, rings."
200
The inner planet's that have moons.
What is "Earth and Mars."
200
The outer planet's with rings.
What is "Jupiter, Saturn, Uranus, and Neptune."
200
What is one scientific argument for Pluto being a planet?
- Planet definition shouldn't be location dependent--eg. if Earth was in Pluto's orbit, it wouldn't clear the neighborhood either
200
This helps protect the earth's atmosphere from solar wind.
What is "magnetic field."
200
Where most of the asteroids are found
What is "in the asteroid belt, in between Mars and Jupiter."
300
The inner planet with the largest temperature extremes.
What is "Mercury."
300
The outer planet with the most moons.
What is "Jupiter."
300
One argument for Pluto being a dwarf planet.
What is "Pluto's composition and orbit don't fit with either terrestial or Jovian planets, there are other objects similar and larger in the Kuiper belt."
300
4.6 billion years ago, our solar system started as this.
What is a nebula or "ball shaped cloud of dust and gases."
300
Differentiate between Meteroid, Meteorite, and Meteor.
What is "Meteroid=in space, Meteorite=landed on earth, and Meteor=in earth's atmosphere."
400
The largest inner planet.
What is "Earth."
400
The two most common elements in the outer planets.
What is "Hydrogen and Helium"
400
What is another dwarf planet besides Pluto?
What is "Eris, Ceres or Makemake."
400
The reson why the rocky and gaseous planets have different composition.
What is "because they formed at different distances from the sun at different temperatures."
400
Where can most comets be found in the solar system?
What is "Kuiper Belt and the Oort cloud"?
500
This inner planet has a thick atmosphere of carbon dioxide and volcanic activity.
What is "Venus."?
500
Name one of the surface features of Neptune.
What is "the Great dark spot", "Scooter" or "windiest planet"?
500
What is the composition of Pluto?
Rock and Ice
500
What is one piece of evidence for the formation of the solar system?
What is "the disc shape of the solar system, the orbits of the planets, the different composition of the rocky and terrestial planets or the presence of comets and asteroids."
500
How does the orbit of a comet differ from most other objects in the solar system?
What is "more eccentric or elliptical, longer period."
