It's the line where part of the moon doesn't light the night. and, if you look, that line serves a purpose of telling what kind of moon night it is without looking at a calendar.

What else can I help you with?

What is the terminator on the Moon and what causes it?

The terminator is the line that separates "day" and "night" (the light and dark part of the Moon). It is interesting to note that close to the terminator, you can see more details, because of the shadows cast by mountains and craters.


What is the name of the dividing line between light and shadow across the moon's disk?

The dividing line between light and shadow across the moon's disk is called the terminator. This is the line that separates the illuminated side of the moon from the dark side.


What is the line that separates the light and dark sides of the moon?

The terminator.


What is the line called that separates the dark half from the light half of the earth?

The line that separates the dark half from the light half of the Earth is called the terminator. This line represents the boundary between day and night, where the sun's light is directly illuminating one side of the planet while the other side remains in shadow. The position of the terminator changes throughout the day as the Earth rotates on its axis.


What are the dark and light parts of the moon?

The abrupt change (line) between light and dark on the moon is called the terminator. The shadow on the moon is there because the sun only lights up half of the moon (which is a sphere) at a time. Also, people on earth always see the same side of the moon. This is because the moon rotates at the same rate as it orbits (kinda tricky). This phenomenon is called tidal locking. The side of the moon we never see interestingly enough has the biggest impact crater in our solar system. So basically as the moon revolves around the earth and the terminator moves across the moon, more and more of the bright part is 'clipped away' until we eventually end up with a moon that looks totally black. This happens at the end of every month and is called the new moon. Here is the link to the wikipedia article. http://en.wikipedia.org/wiki/Lunar_phase

What does a dark line in a spectrum mean?

A dark line in a spectrum, also known as an absorption line, represents a specific wavelength of light that has been absorbed by a substance between the source of light and the observer. The presence of dark lines in a spectrum can provide information about the composition and properties of the absorbing material.

What is a dark line found in a spectrum is called?

A dark line found in a spectrum is called an absorption line. Absorption lines are created when atoms or molecules absorb specific wavelengths of light, resulting in dark lines in the spectrum where that light is missing.
