In spite of the very high temperature at the Earth's centre, the inner core is not in a molten state because the
A
Core has a very high melting point
B
Core is full of gases
C
Great pressure at the centre raises the melting point of the rocks
D
Core is impervious to heat
Correct Answer: Great pressure at the centre raises the melting point of the rocks
In spite of the very high temperature at the Earth's centre, the inner core is not in a molten state because the Great pressure at the centre raises the melting point of the rocks. Our inner core is a solid matter. And it remains solid because of its called iron-nickel which helps most the inner core become solid and other solid and hard particles of it.
