Answer:
1. =
The Lapse Rate is the rate at which temperature changes with height in the Atmosphere. Lapse rate nomenclature is inversely related to the change itself: if the lapse rate is positive, the temperature decreases with height; conversely if negative, the temperature increases with height
2=
Oxygen fuels our cells and helps provide the basic building blocks that our bodies need to survive. ... Every day, about seven hundred billion cells in our bodies wear out and must be replaced. Without oxygen, our bodies cannot build these new cells. Oxygen is also a particularly important part of our immune system.
3= In the atmosphere, air molecules near the surface of the earth are held together more tightly than the molecules in a higher atmosphere because of the gravitational pull of the earth on all the molecules above the surface molecules
