Antarctica contains 26.4 million cubic kilometers (km) of ice. Assume that the average temperature of this ice during the summer months is -20 °C. If all of this ice melted, how many km of liquid water would form at 4
°C?

Express the volume in cubic kilometers to two significant figures.

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).

gold is my favorite solid.
