What would be the color of the sky if thn r9*jh/8 c7phq+wv-1uszjvs e Earth hadtjq6m(a *ebt8 no atmosphere?
参考答案:
If Earth had no atmosphere,
the “color” of the sky would be black (and dotted with stars and planets) at
all times. This is the condition of the
sky that the astronauts found on the Moon, which has no atmosphere. The reason the sky is blue for Earth, is that
the air molecules scatter light from the Sun in all directions, and preferentially
scatter blue light down to the surface.
If there were no air molecules to scatter the light from the Sun, the
only light we would see would be from the stars/planets and directly from the
Sun and the rest would be black.
