How and why earth material seperated into layers.​

Biology
1 answer:
Daniel [21]3 years ago
3 0

Answer:

After several million years, the Earth separated into several layers. Iron, nickel and other heavy metals mostly settled to the core; lighter elements remained in the mantle around the core. The lightest elements, such as oxygen and silicon, floated to the top and cooled, forming a solid crust. Because the Earth was not completely liquid, the layering process was uneven; pockets of heavy elements remained in the crust.

In this case, the membrane is only permeable to water movement and not ions and water molecules move from the side with pure water (which happens to have higher water potential) to the side with 4% sodium chloride until equilibrium in water potential is established between the two sides.
