Limestone – sedimentary rock (rock formed from sediment) Limestone is formed from the shells and skeletons of sea animals so may contain fossils. It is very heavy so it cannot be used for tall buildings. It is easy to cut and carve into detailed shapes. It reacts with acid rain, which corrodes the buildings. light heavy © Serouj © Coyau © Hannes Grobe. Uses: buildings roads wall filler cement

Sandstone – sedimentary rock (rock formed from sediment) Sandstone is made of sand-sized minerals or rock grains. Sandstone comes in many colours such as brown, yellow, red, grey, pink, white and black, but is usually a reddish-brown. It is easy to carve, but can crumble. Uses: buildings paving carvings sharpening tools Sandstone wears away easily in the rain and cold. The surface of sandstone is rough. © Connie Ma © Whitegoast.unk

Shale – sedimentary rock (rock formed from sediment) Shale is made of very fine rounded grains of sediment that have compacted together. Uses: tiles bricks pottery Shale is grey to black in colour. Shale contains mud and flakes of clay. Shale often contains fossils. Shale can be split into thin sheets. Shale is often found in lakes, by rivers, on floodplains and offshore from beaches. © Michael C. Rygel

Chalk – sedimentary rock (rock formed from sediment) Chalk is formed from the shells of one type of sea creature. Uses: toothpaste fingerprint powder blackboard chalk Chalk is white.Chalk is crumbly. Chalk is porous and can hold a large amount of water. Chalk doesn’t weather easily, so chalk cliffs still stand by the sea. © Michael King

Limestone It is a sedimentary rock. It is formed from the shells of sea animals. It may contain remains of fossils. It is used in buildings and to make cement. It is heavy. It corrodes.

Sandstone It is a sedimentary rock. It is made of sand-sized grains of similar sizes. It can be many colours, but is often reddish brown. It feels rough. It is easy to carve. It can crumble. It can be used to sharpen tools.

Shale It is a sedimentary rock. It is made of very fine rounded grains. Fossils are often found in it. It forms layers which can be split into thin sheets. It can be used to make tiles. It is formed in lakes.

Chalk It is a sedimentary rock. It is formed from the shells of a particular sea animal. It is white. It is porous. It is used to write on blackboards.
