A graph with vertical axis K E and horizontal axis Mass with a concave line sloping sharply upward.

A graph with vertical axis K E and horizontal axis Mass with a straight line sloping sharply downward.
A graph with vertical axis K E and horizontal axis Mass with a curved line going first upward and then downward.

The last one or second one

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

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.
