Among the reasons why the earth’s core is believed to consist mainly of molten iron is (are)

a. The density of iron
b. The electrical conductivity of iron
c. The relative abundance of iron in the universe
d. That earthquake S waves do not pass through the core

Expert Solution

The earth’s core is believed to consist of iron as the main constituent due to the following reasons:

(i) It has the right density as that of iron.

(ii) It is a good conductor of electricity that proves the earth magnetism.

(iii) Due to the presence of iron in relative abundance in the universe.

Hence, the options b, c and d are incorrect.

The reason for the iron to be the main constituent of the earth does not include the magnetic properties of iron.

Hence, the correct answer is option (a).

The reason for the iron to be the main constituent of the earth does not include the magnetic properties of iron.
