_______ and heat caused by overlying rocks and ___________________ elements produce magma.

pressure for first word

magma large

The first word you are looking for is "pressure." pressure from the overlying rocks and heat cause certain elements to melt and produce magma.

To find the answer, it is helpful to understand the process of magma formation. Magma is created when solid rock, deep within the Earth's crust, melts due to a combination of high temperatures and pressure. The overlying rocks exert a force on the underlying rock, increasing the pressure. As the temperature rises, the solid rock starts to undergo partial melting, leading to the formation of magma.

Therefore, the pressure exerted by the overlying rocks is one of the factors that contribute to the creation of magma.
