!give an example of an organic non-clastic sedimentary rock, a chemical non-clastic sedimentary rock, and a clastic sedimentary rock. discuss the environment and mode of formation for each example.

Non-clastic rocks have chemical or organic origins. Names of non-clastic rocks are based on their compositions. A calcite-rich rock with many fossils is called a fossiliferous limestone. ... Sedimentary rocks with non-clastic texture include fossiliferous limestone (above left), chert (above right) and coal (right).Clastic sedimentary rocks such as breccia, conglomerate, sandstone, siltstone, and shale are formed from mechanical weathering debris. Chemical sedimentary rocks, such as rock salt, iron ore, chert, flint, some dolomites, and some limestones, form when dissolved materials precipitate from solution.

the core of the sun is so hot and there is so much pressure, nuclear fusion takes place, hydrogen is changed to helium. nuclear fusion creates heat and photons. when the heat reaches the earth it warms the molecules of the atmosphere, and they warm other molecules and so on.
