Apollo 14 landed on part of a vast ejecta blanket that surrounds the Sea of Rains. The Sea of Rains was formed by the volcanic f
looding of a large impact basin that is referred to as the Imbrium Basin. The Imbrium Basin is over 1000 km in diameter. (i) (1 mark] The rocks brought back by Apollo 14 astronauts were used to determine the time at which a very specific event occurred in the history of the Moon. What was that event? (ii) (1 mark) How many interior rings of mountains on the floor of the Imbrium Basin likely got completely covered over by the volcanic flooding of the basin? Explain the reason behind your answer. (iii) (1 mark] (True/False) Apollo 14 was the first mission to bring along a four-wheeled battery-powered roving vehicle that could be driven across the lunar surface by astronauts. The Apollo 15 landing site was hundreds of kilometers away from the Apollo 14 landing site. Figure 1 shows a picture of the Apollo 15 landing site. Apollo 15 landed on the dark flat area at the upper right of the picture. (iv) (1 mark] (True/False) The Apollo 15 lunar module touched down on a lowlands surface located close to the mountainous rim of the above-mentioned Sea of Rains. (v) [1 mark] The mountains seen at lower right of Figure 1 are part of a high mountain range named the lunar Apennines. Is this mountainous region a highlands terrain or a lowlands terrain? Did the Apollo 15 astronauts make any trips from their Lunar Module to the base of this mountain range?

(vi) [1 mark] (True/False) The Apollo 15 landing site is also close to Hadley rille which can be seen in Figure 1. Hadley rille is an example of an arcuate rille. (vii) (2 marks How was Hadley rille formed? • Apollo 15 Figure 1: The landing site of Apollo 15 as photographed from lunar orbit.
