Answer: The statement that correctly describes the rotation and revolution of Mercury is that
"Mercury's rotational period lasts about 58 Earth days and its orbital period lasts about 87 Earth days. This is due to its eccentric orbit and proximity to the Sun".
Explanation: Mercury is the smallest planet among all plants in the solar system. It revolve the sun in 87earth days and rotate round it's orbit in 58 earth days. This means that Mercury revolve more faster round the sun than its rotation.
Mercury is proximity to the sun. This means that Mercury can only be seen near the western horizon after sunset or eastern horizon before sunrises. This is why it can revolve round the sun more faster.
The eccentric orbit of the Mercury makes it rotational movement very slow.

<u>Answer</u>:
When Uranium-238 decays, it emits 8 Alpha particles and 6 beta particles before finally becoming the stable daughter product. The atomic number and mass number of the daughter product is 92 and 234 respectively.
<u>Explanation</u>:
In the process of decay of Uranium-238, it emits alpha particles, and the resultant product is Thorium-234, which turns into Protactinium-234, and this Protactinium-234 undergoes the beta decay to form the Uranium-234.
As per the question, a stable daughter product is created after the emission of alpha and beta particles, this implies that Uranium-234 is a stable product after the decay of Uranium-238. Therefore, the atomic number is 92 (number of protons) and the mass number is 234 (protons+neutrons) which is also the element of the naming.
The landscape of the moon is full or craters made from meteor strikes. It has dead volcanoes and lava flow. I do not know the other part of the question, though, I am sorry.
