Scientists claim that one source of Earth's internal heat is radioactive isotopes. How do radioactive isotopes produce energy that contributes to Earth's internal heat? (AKS 4a, DOK 1)
O A. They give off energy and particles as they break down into other kinds of atoms
OB. They release energy when chemically reacting with atoms that are not radioactive
O C. They absorb sunlight on Earth's surface and then radiate the energy to the ground below them
OD. They are electronically charged and produce energy by interacting with Earth's magnetic field
