5. Earth’s average distance from the sun
WRITE IN NOTEBOOK
Asteroids: chunks of rock left over from when the planets formed
Largest of the solar system bodies
Most common in the ASTEROID BELT (located between the orbits of Mars and Jupiter)

What if an Asteroid struck the Earth?
WRITE IN NOTEBOOK
Comets: asteroid-like objects covered in dust, ice, gases, and metals that develop a fuzzy, cloud-like shell called a coma when they orbit close to the sun,
the ice instantly melts, creating a long, visible tail (a dirty snowball)
Form far away from the Sun
HALEYS COMET

Halley’s Comet
WRITE IN NOTEBOOK
Meteoroid: Large pieces broken off from an asteroid or comet
WRITE IN NOTEBOOKMeteor: A meteoroid that burns up in the Earth’s atmosphere.
Creates a flash of light = ‘shooting stars’
Smallest of the solar system bodies
WRITE IN NOTEBOOK
Meteorite: A meteoroid that does not burn up in the Earth’s atmosphere
It lands and crashes onto the Earth.
Barringer Crater created 50,000 years ago
Hole created when massive meteorite struck Arizona

Homework: “I am” Activity
Directions: 1.Each statement gives you a hint for which one it is.
2.The words can be used more than once.
3.Use your notes to help you fill in the blanks
Due Tuesday in class
How can Earth Sustain Life?3 main reasons….
Think about this….
1. Distance from the Sun Sun = major source of heat and light for
entire solar system Earth = formed in right location = just enough solar radiation = not too hot or too cold,
moderate temperatures

2. Earth’s atmosphereBlanket of gases surrounding EarthProtects humans from harmful radiation It is breathable Made of: nitrogen (78 %), oxygen (21%), and 1 % inert gases (argon, carbon dioxide, water vapor)

Video on layers of the Atmosphere
Picture of the atmosphere
5 Atmospheric Layers: Troposphere: closest to the ground, where all
weather happens (clouds found here) Stratosphere: ozone layer, where airplanes fly Mesosphere: where meteors/rock fragments burn
up Thermosphere: where northern lights ‘Auroras’
occur Exosphere: where spacecraft/satellites orbit, upper
limit of Earth’s atmosphere
WRITE IN NOTEBOOK
3. Earth contains liquid water
Only planet in solar system to contain liquid water
Liquid water is essential for life to exist If we were closer to the sun, our oceans would boil
away while if we were farther away, our oceans would freeze
WRITE IN NOTEBOOK
1. Read the article – Class set2. Answer the questions in your
notebook with your table partner 3. Answers need to be written in
COMPLETE sentences for ANY credit.
