Answer:
TRUE
Explanation:
The earth is comprised of three distinct layers namely the core, mantle and the crust. The core is the extreme interior layer which is comprised of the denser elements like iron, nickel and other siderophile elements. Thee denser minerals are deposited, by sinking into the core of the earth forming the highest density layer. The core was formed about 1 to 1.5 billion years back.
Whereas, the least dense elements were concentrated in the upper region of the earth forming the crust. These are the lighter elements so it did not get sink into the bottom. But still many of these elements are found in association with the core rocks. There occurred constant evolution on the crustal portion of the earth.
Thus, these elements are found in larger proportions in the crust and were formed during the initial formation of the earth.
Hence, the above-given statement is True.
Hey kiddo.
It takes about 365 days, for Earth to orbit the Sun. At 67,000 miles an hour it does so. An elementary way of knowing this concept is knowing how many days are in a year. There are 365 days in a year, thus it takes 365 days for earth to travel around the sun. It may be 366 if you are including the leap year that comes to past in intervals of 4 years. The next leap year is in 2020.
