It is mostly carbon but also contains hydrogen, sulphur, oxygen and nitrogen. It is a sedimentary rock formed from peat, by the pressure of rocks laid down later on top.]]> 2020-06-22 12:20:30 UTC https://padlet.com/atrainor6/2be6p800o77sy9ye/wish/636051753 https://padlet.com/atrainor6/2be6p800o77sy9ye/wish/636140157 Graphite is a gray crystalline allotropic form of carbon which occurs as a mineral in some rocks and can be made from COKE! And is most recognizably used for pencils. Another use is for nuclear reactors. Often mistaken for lead!]]> 2020-06-22 13:36:10 UTC https://padlet.com/atrainor6/2be6p800o77sy9ye/wish/636140157 https://padlet.com/atrainor6/2be6p800o77sy9ye/wish/636670096 Sandstone is a clastic sedimentary rock composed mainly of sand-sized mineral particles or rock fragments or organic material. Most sandstone is composed of quartz or feldspar because they are the most resistant minerals to weathering processes at the Earth's surface, as seen in the Goldich dissolution series.

They form from deposits that accumulate on the Earth's surface. Sedimentary rocks often have distinctive layering or bedding.]]> 2020-06-22 23:46:18 UTC https://padlet.com/atrainor6/2be6p800o77sy9ye/wish/636749921 https://padlet.com/atrainor6/2be6p800o77sy9ye/wish/637620411 Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. Marble is typically not foliated, although there are exceptions. In geology, the term marble refers to metamorphosed limestone

Granite is also what's called a “plutonic” rock, meaning that it forms deep underground. ]]> 2020-06-23 16:52:34 UTC https://padlet.com/atrainor6/2be6p800o77sy9ye/wish/637717717 https://padlet.com/atrainor6/2be6p800o77sy9ye/wish/640007059 composed of large parts of particals of inferior quality or apperanece not fine in material or close in texture.
