Answer:
d) Principle of Conservation of Matter
Explanation:
Principle of Conservation of Matter -
According to the law of conservation of matter, matter is the substance which ac not be created and even it can not be destroyed , hence we need to have the same number of atoms before and after the reaction constant during a chemical change or process of chemical as were number of atoms and type of atoms present before the chemical change .
Hence , from the options , the correct answer is the Principle of Conservation of Matter .

divide both sides by ten
Answer:
Because the gravity of the Earth is pulling on air molecules and pressing it against the ground, our atmosphere is thinner and thinner the higher up you go.
Explanation:
Earth is a planet that has an active core, thus it has a reasonably strong gravitational pull. Gravity manages to keep all things on the surface of our planet and the ones that are in the atmosphere to pull them down or keep them near. This affects the atmosphere as well.
The atmosphere is composed of gases, all of which are made out of atoms and molecules. They are very light, so Earth is pulling them towards it. This has resulted in a situation where the majority of the gases are close to the surface, in the lowest parts of the atmosphere, and as we go up there is less and less of them, so the atmosphere is thinner and thinner as the elevation increases.
