It is the outermost layer of the earth's surface. The Earth’s crust is its lightest, most buoyant rock layer. Continental crust covers 41% of the Earth’s surface, though a quarter of that area is under the oceans. The continental crust is 20 to 80 kilometers thick. Its rocks hold four billion years of Earth history. The remainder of the Earth is covered by oceanic crust. The crust is made of relatively light elements, especially silica, aluminum and oxygen. It’s also highly variable in its thickness. crust is made of relatively light elements, especially silica, aluminum and oxygen. It’s also highly variable in its thickness.

The correct answer is - abolished the boyars.
Peter the Great was not very fond of the situation in which the previous rulers were, where they were heavily dependent on the boyars and also did not had full control of the situation because of them. In order to gain full control and authority in the country Peter the Great decided to abolish the boyars. Instead of the traditional boyar aristocracy, Peter the Great made the state service as the exclusive means of attaining a high position in the bureaucratic system.
The reason why Peter the Great thought that the boyers should be abolished in order for him to strengthen his authority was their influence and power, and he was not wrong. The boyars were the ones that were deciding and controlling the majority of the things in the country. They had very big local influence and power, having their own boyar council as well where they were deciding the politics and economics of the country. Peter the Great did not wanted to be in such a position where other people will decide what should happen in the country and in which manner, as he wanted to be the one that has the only and last say in the matters, so he made his move.
Answer: Native Americans in the British colonies experienced a drastic decline in population due to disease and war brought by Europeans.
Explanation:
Native Americans and indigenous populations around the Americas lost more people to diseases that the Europeans brought than the wars the Europeans visited upon them. It is estimated that the Small Pox and the Plague decimated the Native population, reducing it by an estimated 90%.
The survivors were weak and desolate and so were easily defeated by the Europeans such as the British as seen by the destruction of the Pequots. This was a turning point that allowed the British to easily claim land in the original colonies and establish dominance there.
