Question

. The core of the earth internal is made up of hard rock true or false

Answer 1

false
the inner core, which is a ball-shaped layer made almost entirely of metal.

The outer core is made up of mostly of a combination (called an alloy) of iron and nickel, along with small amounts of other dense elements like gold, platinum, and uranium.

Answer 2

The statement “the core of the earth’s internal is made up of hard rock’s” is a false statement.

It has been found that the earth has an inner core that is solid and molten core by a Danish Seismologist Inge Lehmann. The inner core of the planet Earth is made up of iron and nickel alloy which is completely a solid where the outer layer is liquid that can be seen around the inner core.

It has been estimated that the radius of the inner core is about 70 percentage of the moon surface which is 1,220 kilometers and the temperature is similar to the temperature of the surface of Sun which is 5,430 degree Celsius.
