no, Pyroxene is a Mineral not a rock. Rocks are made up of 2 or more minerals
Because a sedimentary rock goes through the rock cycle.
Pyroxene is a group of minerals.
Granite is a coarse grained igneous rock without Pyroxene.
ORGANIC SEDIMENTARY ROCK`s : Is a type of sedimentary rock because sedimentary rock has three types of sedimentary rock called clastic , chemical , and organic sedimentary rock so yes ORGANIC SEDIMENTARY ROCK is a type of sedimentary rock..........................................
Clastic sedimentary rock.
Peridotite is made only of olivine and pyroxene
a mushroom rock is not a sedimentary rock.
Granite is a coarse grained igneous rock without Pyroxene.
It is then sedimentary rock.
The three main rocks found on this planet are sedimentary, igneous, and metamorphic.
Mechanically formed sedimentary rock , Chemically formed sedimentary rock and Organically formed sedimentary rock.
Most of it you got right. Have you ever heard of something called the rock cycle? If you have, good. If you haven't, here is a link to an excellent diagram: http://www.emporia.edu/earthsci/student/henderson1/rock_cycle.gif Anyway, if you look at the diagram, you can see how igneous rock can transform into sediment, then sedimentary rock, or bypass sedimentary rock altogether and go to metamorphic rock. Sedimentary rock can turn into metamorphic rock with heat and pressure. However, to turn into igneous rock from sedimentary rock, it will have to melt down into magma/lava before becoming igneous rock once again.
