small traces of all elements
All 92 of them.
the chemical composition of human beings are similar to that found in the reminisce of stars after they impload this answer is correct human beings cant be chemically composed like earths crust because we arent formed from silicates and crystals
yes this is true.
The layers of the earth differ in thickness,density,physical state of materials and temperature.
earths mantle is made of silicon,iron,aluminum,calcium,sodium,potassium,magnesium,and mostly oxygen
The eight most common elements in the Earth's crust are as follows (with percentages):Oxygen (O) 46.6%Silicon (Si) 27.7%Aluminum (Al) 8.1%Iron (Fe) 5.0%Calcium (Ca) 3.6%Sodium (Na) 2.8%Potassium (K) 2.6%Magnesium (Mg) 2.1%
earths crust , oceans and atmosphere
A the answer is hydrogen
The oceans, the atmosphere and the biosphere
is it oxygen
These elements are carbon, oxygen, hydrogen for the human body.For the earth crust oxygen, silicon, aluminium, iron.For oceans is water, composed from hydrogen and oxygen.For the atmosphere the important gases are nitrogen, oxygen and argon.
helium is a noble gas and is found in the earth's atmosphere and not in the oceans nor in the earth's crust
earths crust includes ocean floors and
hydrogen
No it does not But it is in the atmosphere and earths crust!!
it has been washed into the oceans as the continental crust has eroded.
i have no clue
Oceanic crust, new oceanic crust is produced by seafloor spreading.
