2. 1 Which factor makes Earth different from all the other planets in the solar system in its ability to support life? A The Earth is exposed to rays from the sun. B The Earth has only one moon that orbits around it. C The Earth rotates in an elliptical orbit around the sun. D The Earth has a breathable atmosphere. 2 Which represents information that is gained as a result of space exploration? A weather and climate patterns that occur on Earth B existence of the sun and the moon in the solar system C how to use coal and natural gas as energy resources D location of plates found upon Earth’s surface

4.  The Solar System consists of:  The Sun and 8 Planets  Multiple moons  Asteroids, Meteors and Comets  Dust, gases and empty space.

5. › 4 Terrestrial Planets: inner planets Mercury, Venus, Earth, and Mars  4 Gas Giants: outer planets › Jupiter, Saturn, Uranus, and Neptune

6. Mnemonic for the 8 Planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune My Very Enthusiastic Mom Just Sent Us Nachos

7.  Asteroids : chunks of rock left over from when the planets formed  Most common in the ASTEROID BELT (between Mars and Jupiter)

8. Comets: asteroid-like objects covered in dust, ice, gases, and metals that develop a fuzzy, cloud- like shell called a coma  sometimes called a dirty snowball

9.  Meteor:  A meteoroid that burns up as it passes through our atmosphere.  known as ‘shooting stars’

10.  Meteorite :  A meteoroid that does not burn up as it travels through the Earth’s atmosphere  It lands and crashes onto the Earth.

12. Reason #1. Distance from the Sun  Earth formed at just the right location  (not too hot or too cold) Sun = heat and light for entire solar system

13.  Reason #2. Earth’s atmosphere  Gases surrounding Earth that protects humans from harmful radiation  It is breathable  Made of: nitrogen (78 %), oxygen (21%), and 1 % inert gases (argon, carbon dioxide, water vapor)

14.  Reason #3. Earth contains liquid water  If we were closer to the sun, our oceans would boil away while if we were farther away, our oceans would freeze

20.  Why colonize Mars?

21.  Let’s start by reading an article about colonizing Mars.  After reading the article, write a paragraph as to why or why not you would like to be one of the first people to colonize Mars. Include your position and give supporting details found in the article….
