Question

1. why is earths inner core solid? earths inner core is solid because it is at a low temperature. earths inner core is a solid because the elements that make it up are only found as solids. earths inner core is solid because of the pressure from the layers above it. earths inner core is a solid because it is at a very high temperature.

Explanation:

The Earth's inner core is solid due to the extreme pressure from the layers above it. This pressure overcomes the high - temperature conditions (which would otherwise tend to make it liquid) and keeps the iron - nickel alloy in a solid state. The first option is incorrect as the inner core has extremely high temperatures. The second option is wrong because the elements in the inner core (mainly iron and nickel) can exist in liquid form under lower - pressure conditions (like in the outer core). The fourth option is incorrect as high temperature alone would not make it solid.

Answer:

Earth’s inner core is solid because of the pressure from the layers above it.
