O Gravity causes materials to undergo radioactive decay, which produces heat and leads to the melting, sinking, and rising of materials. O Gravity absorbs heat, which cools materials and causes them to sink and rise. O Gravity releases heat into space, which cools materials and causes them to sink and rise.
