FOR EXTRA CREDIT (2 points): What 2 metals is the core of the Earth mostly made up of? __

## Step 1The Earth's core is primarily composed of two metals: iron and nickel. These metals are known for their high melting points and are able to withstand the extreme temperatures and pressures found in the core.## Step 2The core is divided into two parts: the inner core and the outer core. The inner core is a solid ball of iron and nickel, while the outer core is a layer of molten metal that surrounds the inner core.## Step 3The outer core is responsible for creating the Earth's magnetic field. This is due to the movement of the molten metal, which generates electric currents and produces magnetic fields.
