Answer 1

yes the earth core is shield of the earth

Answer 2

Answer:

Yes, it is true that the earth's core shields the Earth and this is due to the reason for the production of a magnetic field by the core.

Explanation:

This magnetic field produced by the Earth's core is essential as it saves the Earth's surface from getting stripped off by the Sun's magnetic field.

Without the Earth's magnetic field, produced by the core, the harmful magnetic field of the sun would strip off the earth's surface and the ozone layer protecting it.
