Moon 101 Presentation

Made By: Crocker High School

Questions To Answer In Presentation:

Create a PowerPoint summar izing the geologic history of the sur face seen in each of the three Moon 101 images.

What geologic features are present?

How did they form?

How old are they relative to each other and how do you know that?

Image One In Image One, located in Moon 101 Image Sets, we can fir st note that the ar ea is full of visible highlands and mar e. We have cir cled some of the ver y distinct cr ater s because of their age and pr ofound cr ests. Also in the top r ight of this image, we have found tr acks fr om a lunar r over and what could possibly be the lunar r over .

T hese featur es all for m fr om meteor ites and aster oids that str ike the lunar sur face at a cer tain speed. Since the moon doesn’t have an atmospher e, ther e is no pr otection against these objects like E ar th. Some of these meteor oids can str ike the lunar sur face at 10- 20 kilometer s per second.

How Old Are Craters Compared With One Another/How Do We Know?

Oldest to newest: ● Yellow

● Blue

● Red

● Pink

Image Two The image to the r ight shows a r ille(circled in light blue) and simple cr ater (cir cled in dar k blue).

T his r ille was for med when a lava tube collapsed.

T he simple cr ater for med when an object collided with the moon in that location.

Notice the br ighter appear ance of the sur face in the bottom left, this is either a better r eflection of sunlight or a differ ent sur face composition compar ed to the other ar eas.

Image 3 The image seen on the r ight shows the r ille (boxed in the blue), the lunar highlands (boxed in the yellow), and mar e (boxed in r ed).

T he r ille her e was for med when a lava tube had collapsed.

T he highlands wer e for med when less dense compositions cooled and floated to the top of the lava.

T he mar e is the cooled lava that was not tur ned into highlands. T hus, why it is flat like a fr ozen lake would be.
