Center of The Earth Is Made of Iron?

Center of The Earth

The center of the earth is mainly composed of lumps of iron.

Iron exists at high temperatures of 5,000 to 6,000 degrees.

Why is it so hot?

4.6 billion years ago, small planets collided with each other and became the earth.

The energy generated at the time of the collision still remains inside the earth.

Also, the energy of radioactive elements is reheating.

Most substances inside the earth are liquid due to their high temperature.

Therefore, heavy metal atoms such as iron gather in the center due to attractive force.

When examining the inside of the earth with CT or MRI, it seems that iron lumps are certainly observed.
