Rocks

Foliated metamorphic rocks are among the most visually distinct types of rocks found on Earth due to their layered or banded appearance. These rocks are formed under significant pressure and temperature conditions that cause minerals to realign into parallel layers or planes. Foliation develops as a result of directed pressure, typically in regional metamorphism, where … Read more

These rocks originate from the cooling and solidification of molten rock material, known as magma when it is beneath the Earth’s surface and lava when it erupts above … Read more
