Nick's class did an experiment. They put the same amount of water into four paper cups. To start, the temperature was the same in each cup. They put the cups in four different places. They left them for thirty minutes. Next, they used a thermometer to find the temperature of each cup of water. Predict which location should have the highest temperature.

A) the cup on the desk in the classroom
B) the cup in a sunny spot on the grass
C) the cup outside, in the shade of a tree
D) the cup in the dark corner of the classroom

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).
