Describe the composition and location of the asteroid belt
small, rocky bodies that primarily orbit between Mars and Jupiter
What shape do objects orbit in the solar system orbit and why?
What are two reasons why Mars is not habitable?

No liquid water
How would you describe the orbit of objects in our solar system?
Elliptical
Comets are made of ____ and can be found in these two places...
Ice and Dust
Kuiper Belt and Oort Cloud
The more ___ an object has the ____ gravity it has.
Mass
More
What habitability factor makes sure humans/animals can breathe and plants can grow
Our atmosphere
What are the two categories of planets in our solar system, and what are their compositions (4 each)?
Terrestrial (small, rocky, closer to the sun, and 0-2 moons) and Jovian (larger, gaseous, further from the sun, many moons)
How would you describe our sun? (What is it and size?)
Medium sized star
If I traveled to the moon my _____ would stay the same but but ____ would be _____.
and why?
Mass
Weight
Less
The moon has less mass than earth meaning it has less gravity
Which habitability factor keeps Earth safe from harmful radiation

Write all of the planets in order (closest to the sun -> furthest from the sun)
Including (all planets, Kuiper Belt, Asteroid Belt, Oort Cloud, Habitable zone, and the sun)
SUN, Mercury, Venus, (Habitable Zone- Earth, Mars), ASTEROID BELT, Jupiter, Saturn, Uranus, Neptune, KUIPER BELT, OORT CLOUD
Describe the location and composition of (meteors, meteoroids, and meteorites)
Meteor- Material from outer space that burns up as it enters Earth's atmosphere
Meteoroids- What do we call a meteor before it enters earth's atmosphere
Meteorites- A meteor that survives the passages through the atmosphere and crashes to earth
What would happen if the sun started to lose some of its gravitational pull?
The objects in space would orbit in a different path or float off
