how is the earths core still warm?
☐ leftover heat from the formation of earth
☐ the movement of liquid metal in the core
☐ radioactive decay
☐ contraction in the size of earth when it was forming

Explanation:

The Earth's core remains warm due to two primary sources: leftover heat from planetary accretion (formation) and ongoing radioactive decay of elements like uranium and thorium in the core and mantle. The movement of liquid metal generates the magnetic field, not heat; contraction heat was temporary during formation.

Answer:

Leftover heat from the formation of Earth, Radioactive decay
