- sedimentary
- large rocks are eroded down these piece settle on the sea bed as sediment layers build up the heat and
pressure turns the lowest layers into
- sedimentary rock
- conglomerate made of stones held together with clay or
calcium
- sandstone this is A porus rock made of layers of sand
- coal formed by dead plants
- shale made form tiny particles of clay and is also known as mudstone
- chalk made from the skeletons of sea creatures and
has lots of calcium in it .it can be many colours but if
white its chalk
