Question

Name the most important results of the Apollo missions to the Moon was:
a) the discovery of subsurface water
b) the determination of the age of moon rocks
c) first observation of surface features called craters
d) proof that craters were produced by volcanic eruptions

Answer 1

Hint: Before landing onto the Moon, the surface features had been observed long before Apollo missions. Therefore, there might be some other objects with the pre-information that the moon has surface features called Craters.

Complete step by step answer:
a) the discovery of subsurface water
For discovering the subsurface area, they need huge equipment, but it was the first landing on the moon’s surface. So, it wasn’t possible at that time.

b) the determination of the age of moon rocks
Hence, the surface features had already been observed through the telescope. So, the objective was to study the geology of the rocks. So, the collected samples as well as photos of the surface, which helped determine the age of moon rocks.

c) first observation of surface features called craters
Already mentioned that the craters have been observed from the earth with the telescopes and satellite data.

d) proof that craters were produced by volcanic eruptions
This theory would only be possible after the geology of the rocks had been known to us. Therefore, it comes to the next procedure after collecting the samples of rocks from the surface.

So, the correct answer is “Option B”.

Note:
The Apollo program was designed to land humans on the Moon and bring them safely back to Earth. Apollo 1 was to be the first manned mission of the moon landing program, designed to test out the setup by orbiting Earth.
