How is it possible for white dwarfs to have a lower luminosity than the sun even though it is much cooler?

Biology
1 answer:
ratelena [41]2 years ago
4 0

Answer:

White dwarfs have an extremely small surface area to radiate this heat from, so they cool gradually, remaining hot for a long time.

Explanation:

As a white dwarf cools, its surface temperature decreases, the radiation which it emits reddens, and its luminosity decreases.

What causes large amounts of air to move?
timofeeve [1]

Answer:

There is a term "atmospheric circulation". It is when the air throughout the globe moves around. When the sun heats air near the equator more, and less at the poles. So the equator is warmer. The warm air near the equator moves either towards the south or the north, toward the poles. The warm air also rises up, and the cold air sinks. This is convection, but at a global scale. THis is also the cause of wind.
