Well I’m no meteorologist, but it seems to me the closer you get to the equator the denser the air mass becomes. The farther away it gets from the equator, it obviously gets less dense. I do notice though that the purple are is Greenland, northern Russia and Northern America. Which leads me to believe that it’s more mountain land and it’s density is compared to that of cooler air.
For the first question, the answer would be the hydrosphere (D). For the second it would most likely be the average yearly weather patterns in a given area (C). For the last question, it would be the biosphere (D).
<span>Copper
is a chemical element with symbol Cu and atomic number 29. It is a
soft, malleable, and ductile metal with very high thermal and electrical
conductivity. A freshly exposed surface of pure copper has a
reddish-orange color. Copper is used as a conductor of heat and
electricity, as a building material, and as a constituent of various
metal alloys, such as sterling silver used in jewelry, cupronickel used
to make marine hardware and coins, and constantan used in strain gauges
and thermocouples for temperature measurement.</span>
