Answer:
<u>says Earth was struck by a Mars-sized object and the debris coalesced into the Moon </u>
Explanation:
- The formation of the moon is highlighted by the Giant impact hypothesis or the big splash. It suggests that the moon has been formed out of the debris left by the collision of earth and the mars about 4.5 billion years ago.
- Thus earth and moon have similar orbital spins, moon samples indicate that surface was once molten rock, it has a relatively small iron core, and is if the lower density of the earth.
- In 1898 G.Darwin suggested that moon and earth were formed from the same rocks. Like it has been found that the debris continued to spin around the orbit of the planet and layer on accumulating to form the moon, which is suggested by the <u>debris coalescence hypothesis.</u>
The correct answer is - e. longer life expectancy.
The chronic diseases most commonly affect the older population, due to the weakening of the body as it gets into the latter stages of its existence. Since the life expectancy has increased significantly in the last century, and it is further increasing, even though with lower tempo nowadays, there's more and more people that reach older life, thus the number and percentage of the chronic diseases is ever-growing, especially in the developed countries where the population is in general aging as well.
I think it was the North Sea.
