Early one October, you go to a pumpkin patch to select your Halloween pumpkin. You lift the 3.2 kg pumpkin to a height of 1.2 m , then carry it 50.0 m (on level ground) to the check-out stand. What is the work you do on the pumpkin as you lift it from the ground and how much work do you do on the pumpkin as you carry it from the field?

i would think it's food chain

answer and explanation;

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.
