Answer:
Oxygen
Explanation:
The earth has been divided into three major categories crust, mantle, and core which are further segregated into sub-parts. Since the crust is the outermost layer of the shell, the outer crust of the earth consists of a combination of silicon and oxygen in the majority followed by some percentage of other metals as well. <u>The percentage of Oxygen includes nearly 50% i.e. 46.6% followed by 27.7% of Silicon and the other 25.3 % includes aluminum, iron, sodium, magnesium, etc</u>. Thus, '<u>oxygen</u>' is the correct answer.

The math suggests that for every parsec the rate of moving away is 71 km/s, so when two galaxies are separated by two parsecs we come to 142 km/s speed of moving away from each other. If we take the first light ever (from what is known so far) the cosmic microwave radiation, is 46 billion light-years away from us at all directions, which comes at 4,200 megaparsecs, which comes at 13.7 billion light-years, so it will come to 29,820,000 km/s. It all depends from the distance between the galaxies which is calculated by their type of colour and movement in comparison to other galaxies.
