yes done
Free oxygen
Earth's Atmosphere was named ''Blue Sky'' Because the atmosphere is Blue.
the earth atmosphere is made up of carbon dioxide and oxygen and some helium.
Not all of the elements are present in the Earth's atmosphere.
it is the biosphere and the atomsphere
Yes.
Yes.
All the elements on the earth (excepting of course man made elements) are considered natural chemical elements.
your TV, smart phone, car, head phones, speakers all use rare earth elements. there are many types of rare earth elements that all have different uses.
small traces of all elements
The eighth word that defines all materials on earth is "elements." Elements are the fundamental building blocks of matter and combine to form all substances found on Earth.
