Why do geologists think earth's core contains mostly iron answers com?

There's two main reasons why geologists think that the Earth's core is made out of iron:

1. The seismic waves that travel through the core are moving at a velocity that depends on the properties of the material the waves travel through, and the best fit in this case is the Iron (Fe).
2. The iron is the most abundant metal in the universe.

Answer:

The core corresponds to almost one third of the entire earth mass. It is mainly composed of iron and nickel metals. Therefore, the nucleus can also be called nife due to the presence of these two chemical elements.

This layer is divided into inner and outer core. The outer core temperature ranges from 2,900 to 5,100 km, is more fluid and its temperatures range from 3,000 ° C to 3,800 ° C. The inner core is 5,100 to 6,370 km and is solid.

In 2013 alone, scientists were able to pinpoint the core temperature of the Earth, which can reach 6,000 ° C, the same as the sun.

According to scientists, the temperature of the earth's core is so high that iron can be brought into liquid state. The material, however, returns to solid state as a result of pressure, which causes it to group together again.
