Fossil Fuels and Sedimentary Rocks
Term | Definition |
---|---|
Cementation | dissolved minerals become deposited in the spaces between sediments. These minerals act like glue to hold the sediments together |
Compaction | the weight of layers of sediment upon layer of sediment causes pressure that will squeeze sediments together |
Sedimentary Rock | rock formed when particles of other rocks are deposited in layers and are compacted and cemented |
Coal | a solid fossil fuel that is formed from the remains of plants over very long periods of time. Forms in swampy areas! |
Fossil Fuel | a natural, nonrenewable fuel, such as coal, oil, or natural gas formed in sedimentary rocks, over longs periods of time, from the remains of living organisms |
Natural Gas | a flammable material, in a gaseous form, produced from the remains of marine organisms buried under layers of sediment found near oil deposits. Used for cooking, and heating homes |
Oil | a nonrenewable natural resource produced from the remains of organisms buried under layers of sediments for millions of years |
Sandstone | a sedimentary rock composed mostly of sand-sized grains of mineral, rock, or organic material |
Organic Matter | the waste and remains of plants and animals |
Sediment | solid material that is moved and deposited in a new location |
Nonrenewable Resource | a natural resource that is used up faster than it can be made by nature. Once it is used up, there is no more available |
Deposition | laying down of sediment carried by wind, water, or ice |
Fault | a crack in the Earth’s crust along which movement takes place |
Fossil | preserved remains of plants and animals whose bodies were buries in sediments |
Shale | a fine-grained sedimentary rock containing silt- and clay- sized particles |
Limestone | a sedimentary rock composed of tiny fossils, shell fragments, and fossilized debris. |
