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

A)
solid; high pressure

B)
liquid; high pressure

C)
solid; high temperature

D)
liquid; high temperature

is is b

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

I hope this helps

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.

thank you @pypski and @nadstar

The correct answer is A) solid; high pressure.

To understand why Earth's inner core exists as a solid due to high pressure, we need to explore the conditions at the center of the Earth.

The Earth is composed of several layers, including the crust, mantle, outer core, and inner core. The inner core is located at the very center of the Earth and is primarily composed of solid iron and nickel.

The temperature at the Earth's core can reach up to 7000 degrees Celsius (12,632 degrees Fahrenheit). At this extreme temperature, one might expect the material to be in a liquid state. However, the high pressure at the inner core overrides the effect of temperature, causing the iron and nickel to remain in a solid state.

The immense pressure at the inner core is created by the weight of the Earth's layers above it. The pressure increases with depth due to the weight of the overlying rocks and materials. This high pressure compresses the iron and nickel to such an extent that they remain solid despite the extremely high temperature.

Therefore, the correct answer is A) solid; high pressure.
