Fichas del conjunto (11)
- 1Formation of metamorphic rockMetamorphic means that the rock has changed form.
- 2Types of metamorphismMetamorphic rocks can be formed deep beneath the Earth's surface, where the pressure is very high.
- 3Metamorphic changesHeat and pressure can melt rock, causing a process called recrystallization when new crystals grow as the rock cools down.
- 4Uses of metamorphic rocksMetamorphic rocks are used for a variety of purposes. Many metamorphic rocks are very hard and suited for building work.
- 5The rock cycleThe rock cycle is a model geologists used to explain the endless cycle of change that rocks undergoes.
- 6Contact metamorphismMetamorphism by contact with hot magma as it pushes through the mantle and crust.
- 7FoliationProcess where minerals under pressure become squashed flat and the rock develops layers or bands.
- 8Metamorphic rocksRocks formed when high temperature and pressure alter existing rocks.
- 9Regional metamorphismMetamorphism over a wide area below the crust caused by huge movements of the Earth's crust.
- 10Rock cycleModal geologists use to explain the endless cycle of rocks
- 11Tectonic platesMassive plates that make up the Earth's crust.
