Seth learned in school that iron reacts with oxygen in the air to form iron oxide. The chemical equation is Fe + O2 → FeO2
Seth wanted to see if this would really happen, so he put 13 grams of tiny iron We) pieces on the window sill outside his
,
house. After two weeks, he saw that the iron no longer looked shiny. He checked the mass of the pieces and saw that it went
from 13 to 21 grams. Seth's friend said this shows that matter is not conserved

when atmosphere interacts with biosphere they focuses on on the sources and sinks of green house gases (ghgs) air pollutants, particular matters, water and energy between the earth's surface and the atmosphere. the biosphere affects the climate. the atmosphere and biosphere are in constant interaction with each other, and all living things rely on gases in the atmosphere for life. organisms such as animals take in oxygen gas form the atmosphere to use in every cell of their body for smooth functioning of daily routine exercises.
