Because the Sun only covers half the planet at a time, so the one on the sunny side will get a lot of light from the sun, but the artificial light from light bulbs are in homes and on during night.
Because the earth relies on the light from the sun. Only half of the planet can be lit at any time - due to the fact that light travels in straight lines.
About half of the moon is always lit by the sun. This is because only one half of the moon is visible from Earth at any given time. The amount of light that can be seen from Earth reflects different phases of the moon as it orbits.
No. The Earth is roughly a sphere, so only half the Earth is lit at a time.
Half of the Earth at a time.
You can often see the entire "near side" of the Moon, because even though the sunlit half is very bright, the other part is dimly lit by reflected Earthlight. However, the official answer to your question is probably "one quarter". You can only see one-half of the Moon, and only half of that is lit up by the Sun.
Beause there is only one sun in our solar system.
Roughly half of the moon is lit by the sun at all times. The moon revolves around the earth so we only see the part of the moon that actually faces the sun, which is how the moon has phases.
The moon is ALWAYS 50% (+/-) illuminated. Though we only see all of the half lit side when the moon is opposite the sun (Full Moon).
I think this person means changing phases and don't worry I'll make my answer as true and clear as it can be. Yes half of the moon is lit up. except when eclipses occur it is lit up by the suns reflected light.
Half of the moon is always lit up by the sun at any given time, and the moon orbits the Earth so us observers on Earth will see different amounts of the moon lit up. These different "shapes" we see are called the phases of the moon.
Unless there is a lunar eclipse, half of the moon is always lit by the sun. Sometimes we see the lit half dead on (full moon), sometimes side on (half moon) and sometimes we don't see any of the lit surface (new moon) - usually we see something in between.
