How can you determine the relative ages of the moon's maria and highlands? a. compare the relative magnetic field above each region radioactive dating of rocks from each region b. compare the number of craters that are seen on each region c. compare the relative depth of the regolith

what is the actual question though?

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.

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
