Think back to the "Skate Park" Lab and how the skater rolled back and forth on the ramp when there was no friction. After he rolled up and down the ramp a few times,
how did the potential energy compare to the total energy at the bottom of the
ramp? Make sure you explain in your response whether energy is conserved or not in
the system. Make a claim answering the question, give evidence to support your
a
claim, and provide reasoning for your evidence supporting the claim.

he . if i may ask what i your question exactly?

explanation:

powerful computers now, not then

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.
