This project and its actions were made possible due to co-financing by the European Fund for the Integration of Third-Country Nationals EAL Nexus resource Rocks - sedimentary Subject(s): Geography, Science Age group(s): 8–11, 12–14, 15–16 Topic: Types of rocks Licence information | This resource is free to use for educational purposes. ©British Council 2014 Source | This resource was originally developed from a resource on TES by j33ffa , Charlotte Hurley and Alison Fisher and has been adapted by EAL Nexus. Limestone – sedimentary rock (rock formed from sediment) Limestone is formed from the shells and skeletons of sea animals so may contain fossils. © Hannes Grobe. It is very heavy so it cannot be used for light tall buildings. It reacts with acid rain, which corrodes the buildings. © Coyau It is easy to cut and carve into detailed shapes. © Serouj heavy 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. The surface of sandstone is rough. Sandstone wears away easily in the rain and cold. © Connie Ma It is easy to carve, but can crumble. © Whitegoast.unk Uses: • buildings • paving • carvings • sharpening tools Shale – sedimentary rock (rock formed from sediment) Shale is made of very fine rounded grains of sediment that have compacted together. Shale often contains fossils. Shale is grey to black in colour. Shale contains mud and flakes of clay. © Michael C. Rygel Shale can be split into thin sheets. Shale is often found in lakes, by rivers, on floodplains and offshore from beaches. Uses: • tiles • bricks • pottery Chalk – sedimentary rock (rock formed from sediment) Chalk is formed from the shells of one type of sea creature. Chalk is white. © Michael King Chalk doesn’t weather easily, so chalk cliffs still stand by the sea. Chalk is crumbly. Chalk is porous and can hold a large amount of water. Uses: • toothpaste • fingerprint powder • blackboard chalk Limestone Sandstone Shale Chalk 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.
