Animals can largely benefit
Managing information and thinking:
from having limestone in their diet so it is often added to their feed. Find out why.
Metamorphic Rock
Metamorphic rocks began life as igneous or sedimentary rock. When these two rock groups come into contact with great heat (from magma) or great pressure (due to folding), they can be changed into completely new rocks known as metamorphic rocks.
Marble
Marble is a metamorphic rock. It is formed when limestone is placed under great heat and pressure. In its pure form, marble is white, but it can also be green, red or black. Marble has a hard texture and is used in making headstones, fireplaces, monuments and tiles.
White marble can be found on Rathlin Island, green marble in Connemara, red marble in Cork and black marble in Kilkenny.
