Why can steam at 100°c cause more severe burns than the same mass of liquid water at 100°c? a. because when liquid water changes to a gas, it loses energy. b. the steam has more thermal energy than the liquid water. c. the steam has less thermal energy than the liquid water. d. because the steam takes up more volume than the liquid water. this is science

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.
