Answer and Explanation:deposition has been occurring on earth for a very long time. as time goes by, more deposits form layers on the earth, including the remains of animals and plants that would later become fossils, burying the previous deposits in another layer of newer deposits. therefore it follows that layers which are found deeper are older than those found in layers near the surface....

<h3>Stoichiometric problems</h3>
The balanced equation of the reaction would be as follows:

The mole ratio of methane to carbon dioxide is 1:1.
10 grams of methane will give 10/16 = 0.625 moles
0.625 moles of carbon dioxide would give 0.625 x 44.01 = 27.506 grams.
Thus, 10 grams of methane will produce approximately 27 grams of carbon dioxide stoichiometrically.
The reaction obeys the law of conservation of mass because the atoms of all the elements before and after the reaction are balanced.
