question: Mark studies rocks for a living. He is curious if rocks deeper in the Earth will be warmer or cooler. If Mark were to take the temperature of a rock that is half a mile into the Earth's surface, and then take the temperature of a rock 1 mile into the Earth's surface, he would find that the rock 1 mile into the Earth's temperature is
