Fog usually contains about 0.05 to 0.5 grams of liquid water per cubic meter of air.

Fresh grass typically weighs about 0.5 to 0.7 kilograms per liter (roughly 1.1 to 1.5 pounds per quart).

Heat is energy, so it has mass equivalent through E = mc^2.

Lava typically weighs about 2,600 to 3,100 kilograms per cubic meter, depending on composition and trapped gases.

Lightning is not a solid object with ordinary weight, but its energy has a tiny mass equivalent.

Pollution in the air can range from trace amounts to many tons over a city, depending on what you measure and over what area.

Just 1 millimeter of rain falling on 1 square meter equals 1 liter of water, which makes rainfall easy to turn into weight.

Snow usually weighs between 50 and 500 kilograms per cubic meter depending on how dry, fresh, compacted, or wet it is.

Sunlight has zero rest mass, but its energy has an equivalent mass through E = mc^2.

The Amazon Rainforest's total biomass is estimated to weigh around 80 billion tons, including trees, plants, soil, and organic matter.

The Amazon River carries roughly 209,000 cubic meters of water per second.

Earth's atmosphere weighs about 5.15 quadrillion metric tons, or roughly 5.15 x 10^18 kilograms.
