Question

3]. core with reference to the following points
a. Outer core,, b. Inner core​

Answer 1

Answer:

CORE :-

• Earth's core is the very hot, very dense center of our planet. The ball-shaped core lies beneath the cool, brittle crust and the mostly-solid mantle. The core is found about 2,900 kilometers (1,802 miles) below Earth's surface, and has a radius of about 3,485 kilometers (2,165 miles).

A. OUTER CORE :-

• Earth's outer core is a fluid layer about 2,400 km thick and composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle. Its outer boundary lies 2,890 km beneath Earth's surface.

B. INNER CORE :-

• Earth's inner core is the innermost geologic layer of the planet Earth. It is primarily a solid ball with a radius of about 1,220 km, which is about 20% of Earth's radius or 70% of the Moon's radius. There are no samples of Earth's core available for direct measurement, as there are for Earth's mantle.
