Answer

Brief Explanations:

The outer - core is composed mainly of iron - nickel alloy. High temperatures in the outer - core cause this alloy to melt, resulting in a liquid state. A tarry consistency doesn't explain the liquid state. The outer - core is denser than the mantle. Extreme pressure would tend to make it solid rather than liquid.

Answer:

The iron - nickel alloy melts due to hot temperatures.
