IM SORRY THIS ISNT CHEMISTRY BUT GEOLOGY DOSENT APPEAR AND I NEED HELP WITH IT. THERE IS 2 OTHER SAMPLES BUT THEY CANT FIT IN. THE SAMPLES ARE IN ORDER. 4. Examine the photographs of sediment samples in the Unknown Samples Gallery, which is under Materials in the Lesson Resources. Match the pictured samples to the environments described in the Student Guide.

Explanation:

Sedimentary rocks

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).

b.

the accuracy of the data.
