That depends in part on what you mean by "substance", and whether you measure by volume, by mass, or by number of moles! The most common elements (water is not an element) in the Earth's crust (atmosphere, oceans, land, up to a depth of a few kilometers), by mass, are oxygen, silicon, and aluminium - in that order.
Iron
Oxygen is the most abundant element on Earth. It comprises 49.5 percent of the total mass (amount) of the Earth's crust, waters, and atmosphere.
Plankton
Hydrogen dioxide is the most common oxide on the surface of the earth. This substance is sometimes called the universal solvent. It's chemical formula is a familiar one - H2O - and we know it as water.
there are only three, and they are the most common for any substance rarely ever will you see plasma, anyways they are solid (ice) liquid (water) and gas (water vapor)
