No, the outer core is not made of solid metal. It's made of liquid iron and nickel, along with smaller amounts of other elements.

Here's why:

* Temperature and Pressure: The outer core is incredibly hot (around 4,500°C) and under immense pressure from the weight of the Earth above it. These conditions are not conducive to a solid state.

* Fluid Flow: The liquid metal in the outer core is constantly moving, creating electric currents that generate Earth's magnetic field. This motion wouldn't be possible if the outer core were solid.

So, while the inner core is solid, the outer core is a swirling, liquid metal ocean!
