Sedementary rocks: rock made of layers of compressed sediments.
sediment: small pieces of rock.
Pressure: The force of objects pushing on other objects.
weathering: Wind water and ice break down existing rocks.
Erosion: Wind water ice or gravity caring the sediments away.
Deposition: A process by which wing bar water drop sediment in a new location.
compaction: more and more sediments are layered on each other the weight of new layers compact or press the sediment together.
Cementation: The layers become stuck or glued together making sedimentary rocks.
process: A series of natural occurrence that produces change or development.
fossil fuels: call oil and natural gas formed over millions of years from deposition of organic materials in sedimentary rock layers.
organic matter: The waste and remains of plants and animals.
Decay: to rot and break down into smaller parts.
Oil: A flammable liquid produced from remains of marine organisms buried under layers of sediments for millions of years.
imprint: A mark or depression made by pressure.
Coal: natural resource made from remains of swamplands millions of years ago.
natural gas: inflammable material without a definite form produced from remains of marine organisms are buried under layers of sediment found near oil deposits.
Fossil: served parts or traces of animals and plants that lived in the past.
