Yeah
Granite, because it is composed of various and different quantities of minerals, does not have a specific formula. However, granite is composed mainly of the minerals potassium feldspar, quartz, hornblende, and micas, which are in turn composed of varying amounts of the elements silicon, oxygen, aluminum, calcium, iron, magnesium, manganese, and titanium.
Sandstone is a sedimentary rock composed mainly of sand-size mineral or rock grains. Most sandstone is composed of quartz or feldspar because these are the most common minerals in the Earth's crust.
Limestone composed of mainly Cacieum Carbonate(CaCO3)
The carbonate sands would indicate that they are the weathered and eroded remains of the skeletons of small marine animals (like corals) whose exoskeleton is composed of these minerals.
No, inorganic as it consists mainly of quartz and other minerals
Slate is mainly composed of the minerals quartz and muscovite or illite
Ultramafic rocks are made of ferromagnesian minerals.
No, silt contains quartz and feldspar and is inorganic
Yeah
Marble is composed mainly of the mineral calcite, but because of the presence of other minerals, marble is a rock, not a mineral.
Fe (Iron) and Mg (Magnesium) that's why it's called ferromagnesian
Igneous rocks are composed mainly of silicate minerals. Granite is mostly quartz, feldspar and mica. Basalt is mainly feldspar, pyroxine and amphibole. Diorite can be a mixture of all of these minerals. Peridotite is mainly olivine (peridot) and pyroxine.
The crust is mainly composed of rock. The rock of the crust is composed of silicon minerals. It also has great rates of oxygen in it.
Chert is actually not a mineral. Chert is a type of sedimentary rock that is made up of many minerals. It is composed mainly of the minerals chalcedony and quartz.
Cells are not composed primarily of inorganic molecules. This is because cells are found in living things which are made up of organic matter.
The Sun is composed mainly of hydrogen in helium, with trace amounts of a few metals and gases.
