Question

‘The inner core is in solid form’. Substantiate the statement.

Answer 1

Due to increased pressure, the inner core of earth solidify

Explanation:

• The inner core of the earth is in solid form.
• As we move from the outer core or surface to the inner core of the earth the pressure increases gradually.  
• This increase in pressure is responsible for making the inner core dense and solid.
• Also, the inner core has many deposits of minerals that exist in solid form.  
• Due to increased pressure, iron and Nicole solidify in the inner core.

Answer 2

The inner core is in solid form.

Explanation:

• The inner core of the earth is made of a solid ball of 1,220 km in radius and is about 20% of the radius of the planet, the evidence has been collected from the seismic waves and the magnetic fields.  

• As the seismic waves are reflected at the boundary of the inner core and outer core due to the Lehmann discontinuity and can be detected by seismographs.

• The estimated thickness ranges from 1950 to 300 km which implies the inner core is crystal iron. The magnetic field of the earth is affected by the presence of heat that flows through it.

• As given by the theory of the planetary formation, the inner core is believed to be in a solid iron and nickel alloy form.
