In the early stages of its formation, Earth became hot enough that some of its solid materials turned to liquid. Which of these factors did not directly contribute to Earth’s high internal temperatures?

x would be the most and the least would be y because there are more fruit   and seeds than flock z has insects

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
