Material on the moon is like our crust and mantle. Very little iron is there.
No atmosphere on the moon due to high energy impact.
Same oxygen atoms are on the earth and moon that are different from ones found in comets and meteoriods!
Collision Theory Evidence !
What theory best describes the formation of the moon? Collision Theory Mastery Question
What evidence supports the collision theory of lunar formation?
Similar surface composition
No atmosphere due to the force of impact
Similar oxygen atoms – different than on other celestial objects
Why do you think we have not yet found the point of impact on Earth? Self-expressive Question
Comparisons: 1/4 our diameter 1/6 our gravity About 240,000 miles away
Lunar far side looks very different from the side of the moon we always see!
NASA's Apollo missions Goal was to put men on the moon to explore and conduct scientific experiments. Neil Armstrong was the first person to walk on the moon. He did so on July 20, 1969. Video clip of Apollo Missions

Why is the footprint still visible? Why hasn’t it changed?
No agents of weathering and erosion
Understanding Question – connection to previously learned material
