The terminator is the line - on any planet - between light and dark.... but it is rarely a 'line' in the true sense here on Earth, it's more of a zone.
The main thing to remember is that the Earth is a sphere. It's the same sort of shape as a basketball. The Earth blocks out the Sun so it can't light the side of Earth facing away from the Sun. A simple experiment: Take a ball and hold it to a light. The half of the ball facing the light will be lit up and the other side will be dark. Rotate the ball and different parts will now be light and dark. That's like what happens as the Earth rotates. That's why a place on Earth has day then night.
Dark reaction needs energy. this energy is supplied by light reaction
Earth does have a dark side. When you are on that dark side it is called night. Both Earth and the moon get their light from the sun. Since they are both spherical and there is only one sun in our solar system, the sun can only light up half of each object at a time.
Well.......both types of eclipse have to do with blocking the sun, or making shade. In a Lunar Eclipse, the Earth gets right between the Sun and the Moon, casting a shadow over the moon. The moon goes somewhat dark, appearing dark reddish in the sky. In a Solar Eclipse the Moon gets between the Sun and the Earth, and the moon casts a shadow on the Earth. From Earth we see the dark disk of the moon sliding over the bright sun, blocking the light.
It is day time on the part that the sun is shining on, while night on the other part. Being more precise, it is different stages of the day on the bright areas. Where the division between the light and dark parts are, it is morning or evening, and on other parts it is different stages of the day. It is the same on the dark side, being different stages of the night, from just after sunset to just before sunrise.
Terminator or Terminus depending on how Latin you are.

Terminator
The line is called the terminator
a contrast between light and dark.
the earth is between the moon and the sun. so that the solar light cant reach the moon that is in the earth's shadow, and becomes dark.

It is dark in california baby
The contrast between light and dark- APEX
You can imagine a rotating cube, that is illuminated by a source of light on one side. The cube would have a dark side and a light side, and as it rotates, the surface of the cube would change from dark to light, and light to dark, much like the existing situation on the planet Earth. The main difference is that the changes in lighting would not be as gradual as they are for a sphere. Surfaces of the cube would go from light to dark, or dark to light, much more suddenly.
