Question

The modern Earth is a layered planet with an inner core, outer core, mantle and crust. Describe how this structure developed, during what time period, and its relationship to the Moon forming event.

Answer 1

The primary layers of the Earth, beginning from its center, are the internal core, the outer center, the mantle, and the crust. These layers shaped as the forming blocks of the Earth, called planetesimals, clash and crash into underneath their very own gravity 4.5 billion years in the past. At that point, the heaviest factors (like iron and nickel) fall to the center, even as the lighter elements (like silicon, oxygen, and carbon), form the mantle and crust concentrating at the upper surface.

The moon formed at the same time when the collision occur. The impact gathered some material into earth's orbit, later the blasted material accreted due to gravitation and formed the moon.
