Earth's inner core exists at temperatures as high as 7000oC. It exists as a _______ due to the _________.

Question

A)
solid; high pressure

B)
liquid; high pressure

C)
solid; high temperature

D)
liquid; high temperature

Answer 1

is is b

Answer 2

The inner core is solid, the outer core is liquid, and the mantle solid/plastic. This is because of the relative melting points of the different layers (nickel–iron core, silicate crust and mantle) and the increase in temperature and pressure as depth increases.

The immense pressure from the other parts of the planet keep the extremely hot iron of the Earth's inner core from melting. The iron in the inner core maintains a temperature of around 9,000 to 13,000 degrees Fahrenheit.

I would go with A

Answer 3
