How do the radiogenic ages of the samples brought back by Apollo 11 and 12 compare to the “typical” ages of rocks from the Earth?
There is no way to compare the ages
They are much older
They are much younger
They are about the same age

3.6 … 0.8
3.6 … 3.2
0.8 … 3.6
3.2 … 3.6
0.8 … 0.8
The mare surfaces at the Apollo 11 landing site were much darker than the mare surfaces at the Apollo 12 landing site. This was due to differences in the amount of ___ in the basalt samples.
The glass from the Apollo 12 site is much richer in ____ than the basalt from the Apollo 12 site.
The viscosity of lunar basalts is much lower than the viscosity of terrestrial basalts. This is due to differences in the amount of ___ in the basalt samples.
The major process that has changed the Lunar surface during the past 2 billion years is ….
Volcanic lava flows
Formation of giant impact basins
Cooling of basalt
Moon-quakes last longer than Earthquakes because the Moon ___
is smaller than the Earth
is drier than the Earth
is older than the Earth
has less gravity than the Earth
Why was it unexpected to find glass on the surface of the Moon?
glass needs an atmosphere to form
glass is only formed in wet environments
glass is quickly destroyed by impacts
glass is unstable on the surface of the Earth
