Granite
A "metamorphic" rock forms.
Coal.
Heat and pressure causes Metamorphic Rocks to form.
Two causes of blood pressure changes that might occur in a person within a given day are, cardiovascular system and the heat that comes off the heart.
When sedimentary rock is changed by heat and pressure, it forms metamorphic rock. This process is known as metamorphism, where the existing rock undergoes changes in mineral composition and texture without melting.
Rock is continually recycled into new forms of rock by the processes of weathering, erosion and lithification, melting and solidification, or by pressure and/or heat causing recrystallization and changes in mineralization.
You first need to get an oven. Then seal the oven door with silicon glue so no air can get out. Then turn on the oven, a few minutes later, turn the oven off. Since heat causes expansion of Air, it makes more pressure, and pressure causes heat. Then the heat causes expansion, expansion causes pressure, pressure causes heat. and the cycle goes on and on..........
maybe heat can make have the pressure
The primary agent of contact metamorphism is heat from the intrusion of magma into surrounding rocks. This heat causes changes in the mineralogy and texture of the rocks without significant pressure changes.
A metamorphic rock forms by heat and pressure
heat and pressure
Weight causes density, density causes pressure, pressure causes heat. Heat and pressure change rocks into other rocks, which are metamophic.
