Heat can transfer between two objects touching one another. What type of heat transfer is this? What will the temperature of both objects be after these objects remain in contact for a long period of time?

Explanation:

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.

so, the best possible answer to this question will be option d- to harden materials to form different parts of earth’s layers
