What percentage of the earth is organic?
Soil organic carbon is a measureable component of soil organic matter. Organic matter makes up just 2–10\% of most soil’s mass and has an important role in the physical, chemical and biological function of agricultural soils.
What is the percentage of Earth’s mass?
The mass of the Moon is about 1.2\% of that of the Earth, so that the mass of the Earth+Moon system is close to 6.0456×1024 kg. Most of the mass is accounted for by iron and oxygen (c….

How much does all life on Earth weigh?
about 1.1 trillion metric tons
While the mass of Earth’s life forms stands at about 1.1 trillion metric tons (1.2 trillion U.S. tons) and has not changed much in recent years, the so-called “anthropogenic mass” of artificial materials is growing exponentially.
How much mass does the average human take up?
The average human has a mass of about 62 kg, or 62,000 grams. That means the average volume of a human is 62,000 cubic centimeters. To get the total volume of the human race, just multiply that by 7.6 billion: 470 trillion cc. That’s a weird amount to grasp.
What percentage of the Earth is water by mass?
Although water covers 70 percent of the Earth’s surface, water is actually a rare substance that represents just 0.05 percent of the Earth’s total mass.
What percentage of Earth is rock?
Of the rocks exposed on the Earth’s surface, 66 percent (±3.5 percent) are sedimentary and 34 percent are crystalline, at the 95 percent confidence level. Extrusive igneous rocks average about one-fourth of all crystalline rock outcrops, with the highest percentages in Asia and South America.
What percentage of Earth’s mass is iron?
The correct answer is Approximately 32\% – 35\%. By mass, the Earth is composed of mostly iron (35 percent), oxygen (30 percent), silicon (15 percent), and magnesium (13 percent). It is made of distinct layers: a thin crust, upper mantle, lower mantle, outer core, and inner core, as well as transition zones.
What is human made out of?
Almost 99\% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85\% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium.
What percentage of life on Earth is human?
0.01\%
Humans comprise a very small share of life on Earth — 0.01\% of the total, and 2.5\% of animal biomass [animal biomass is shown in the right-hand box on the visualization above].
How much space does a human take up?
The volume of a human is about . 0664 cubic meters, putting the combined volume of all humans at about 485 million cubic meters. When we reduce that to one quadrillionth of its size, we get . 485 cubic centimeters.
What is soil organic matter?
Page 1 Guides for Educators. Soil organic matter (SOM) is the organic component of soil, consisting of three primary parts including small. (fresh) plant residues and small living soil organisms, decomposing (active) organic matter, and stable organic. matter (humus).
How much does the Earth’s mass change per year?
Earth’s mass is variable, subject to both gain and loss due to the accretion of in-falling material, including micrometeorites and cosmic dust and the loss of hydrogen and helium gas, respectively. The combined effect is a net loss of material, estimated at 5.5 × 10 7 kg (5.4 × 10 4 long tons) per year.
What is the mass of the Earth in US customary units?
U.S. customary. ≈ 1.3166 × 1025 pounds. Earth mass ( ME or M⊕, where ⊕ is the standard astronomical symbol for planet Earth) is the unit of mass equal to that of Earth. The current best estimate for Earth mass is M⊕ = 5.9722 × 1024 kg, with a standard uncertainty of 6 × 1020 kg (relative uncertainty 10 −4 ).
What is the total biomass of all organisms on Earth?
The sum of the biomass across all taxa on Earth is ≈550 Gt C, of which ≈80\% (≈450 Gt C; SI Appendix, Table S2) are plants, dominated by land plants (embryophytes). The second major biomass component is bacteria (≈70 Gt C; SI Appendix, Tables S3–S7), constituting ≈15\% of the global biomass.
