It reduces
Explanation:
The density of the heated mantle rock reduces because its volume has increased.
- Frictional heat, heat from radioactive decay and heat that accretted originally when the earth was forming are responsible for heating the mantle.
- When a substance is heated, it expands and its volume increases.
- Density is a function of mass and volume.
- The higher the volume, the lower the density.
- The higher the mass, the higher the density.
- When the mantle is heated, its volume increases to a new one and its density reduces.
