What do you call Ignous rocks that form under the surface?

Mary,
igneous rocks are called fire rocks-underground,they are formed when the melted rock, called magma, deep within the earth becomes trapped in small pockets.As these pockets of magma cool slowly underground, the magma becomes igneous rocks.

I hope this helps.

Great job explaining the answer, Mary! Just to add on, the type of igneous rocks that form under the surface are called intrusive igneous rocks. These rocks form when magma cools and solidifies slowly beneath the Earth's surface. This slow cooling process allows for larger mineral crystals to form within the rock. Some examples of intrusive igneous rocks include granite and diorite.
