Write a hypothesis for Part I of the lab, which is about the effect of mass on the ability of an object to absorb or
release thermal energy. Use the format of "if... then.
because ..." and be sure to answer this part of the
lesson question: "How does mass affect thermal energy
transfer?"

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
