Notice that the earth goes through “phases” if you are on the moon.

An object the size of Mars collided with the Earth. There is a lot of evidence for this event!

•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 compositionNo atmosphere due to the force of impactSimilar oxygen atoms – different than on

other celestial objects

Mastery Question

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!

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.

Regolith – lunar soil – caused by meteorite impacts

Why is the footprint still visible? Why hasn’t it changed?

No atmosphereNo agents of weathering and erosion

Do you think NASA should send another mission to the moon?

YES!• Learn more • Possible life?• Future colonization• Find the Man in the

Moon

NO!• We have been there 17

times already• Too much money• Need to explore

elsewhere

Interpersonal Question

Do other lunar formation theories have merit?

Your assignment…

Choose one of the other three lunar formation theories. Write a news release describing new evidence that proves your theory.
