During the formation of metamorphic rocks, what lead to increased heat? check all that apply. sun warms rocks. magma pockets rise. friction occurs between sliding rocks. lava at earth’s surface flows over rocks. rocks beneath earth’s surface are forced towards the mantle.

The metamorphic rocks are formed by the solidification of the lava after the volcanic eruption. Sometimes because of underground heat and pressure the rocks will become magma. This results in the contact metamorphism when the existing rocks comes in contact with the newly produced magma. These rocks experiences friction among themselves and exerts pressure over the earth crust.

On the basis of the above description, the following statements are relevant:

Magma pockets rise.

Friction occurs between sliding rocks.

Lava at earth’s surface flows over rocks.

Options (2), (3) and (5)

Explanation:

Metamorphic rocks are those that are formed when a particular rock type is subjected to extremely high pressure and temperature condition. These are high-grade rocks and are straightly obtained from the previously existing sedimentary or igneous or other metamorphic rocks. For example, Quartzite, Gneiss, Schist, and Marble.

The main heat supply for the formation of this type of rocks is from the friction that occurs when two rock types that take place along a fault plane, geothermal energy (heat) and also the heat supplied from the magma present below the earth's surface.

The magma in the large magma chambers, when rises upward, and it radiates heat energy to the adjacent country rocks, as a result of which the rocks experiences a relatively higher temperature. Again, the geothermal heat energy is responsible for the increasing temperature of the rocks where the rocks are pushed towards the mantle where the temperature is extremely very high.

When two plates slide past one another along a fault plane, it generates a certain amount of heat energy that increases the temperature of the rocks.

These are some of the reasons how heat energy is supplied to a rock that helps in the process of metamorphism.

Thus, the correct answers are options (2), (3) and (5).
