The asthenosphere is the viscous region of the upper mantle of the Earth that lies just below the lithosphere.
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.
Nitrogen Well, Oxygen is the most abundant element on earth if you include the Air, Water and Land. Oxygen makes up 50% of the earth. But Nitrogen is contained most in the air (atmosphere), making 78% of the air.
solid, liquid and gas are the three states of a substance essential for life on earth.
Nitrogen is the substance that makes up most of earth's atmosphere making up 78% of the gases
By viscous, I think you mean viscosity. Viscous is a adjective referring to the thickness of a substance; therefore, yes, ketchup is somewhat viscous.

viscous
The lithosphere is the least viscous because it is brittle.
Viscosity is the thickness of a substance; how easily it flows. Molasses> very viscous Water-> not so viscous

A zoogloea is a colony or mass of bacteria embedded in a viscous gelatinous substance.
This is probably the interstitial fluid.
The more dense a substance is, the more viscous it is.
No. For instance oil is more viscous then water but has a lower density
water is the and most found substance also earth and air
