There is about 50% of the Earth that is lit at one time. Ray of light fall paralell across the Earths surface, only lighting 50% of the Earth at one time.
it depends what phase the moon is in search phases of the moon then you'll understand
The Beacons of Gondor will be lit throughout Middle-Earth.
Half of the Earth at a time.
Daytime.
Only if you are referring to earth as a percentage of earth, then earth is 100% of earth
One hemisphere is always lit except when the moon is occulted by the earth.
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).
because the sun is hot and bright
craters
Very slightly more than 50%.
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.
The percentage of the Moon that is lit by the Sun varies depending on its position in its orbit. At certain points, half of the Moon's surface may be illuminated (50%); this is known as a First or Third Quarter Moon. This occurs because we see different portions of the illuminated half from Earth as the Moon orbits.
