Study Notes
Metamorphic Rocks Formation
- Metamorphic rocks are known as "changed rocks" due to the alteration of minerals when exposed to heat and pressure.
- Heat within the Earth is a significant factor, causing rocks to undergo mineral changes, typically occurring between 100°C and 800°C.
- Rocks begin to melt into magma at temperatures exceeding 800°C.
- Great pressure inside the Earth also affects rocks, altering the form of minerals and resulting in a flattened texture for those buried deep underground.
- Both igneous and sedimentary rocks can transform into metamorphic rocks when subjected to heat and pressure.
- Chemical changes in minerals can occur when rocks are heated, influenced by surrounding magma and chemical solutions.
