The type of rocks produced by changing other rocks with high temperature and pressure underground are called metamorphic rocks.

Here's a breakdown:

* Metamorphism: This process refers to the transformation of existing rocks (igneous, sedimentary, or even other metamorphic rocks) into new rocks under intense heat and pressure deep within the Earth's crust.

* High Temperature and Pressure: These conditions cause the minerals within the original rock to recrystallize and change their structure, leading to the formation of new minerals and textures.

* Examples of Metamorphic Rocks: Marble (from limestone), slate (from shale), gneiss (from granite), and quartzite (from sandstone) are all examples of metamorphic rocks.
