Which of these is a freshwater reservoir? a. gulf of mexico b. pacific ocean c. atlantic tidal basin d. antarctic polar ice

Antarctic polar ice is a freshwater reservoir. The antarctic polar ice

undergoes physical changes such as freezing.

The antarctic polar ice contains fresh water and a smaller volume which

makes it easier for it to undergo freezing as it has a lower freezing point as

to when compared with salt water bodies.

Gulf of Mexico, Pacific ocean and Atlantic tidal basin all contain salt water

which makes freezing more difficult as it contains a larger volume and high

freezing point.

Antartic polar ice is the answer.

they both have a y in them

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).
