The imaginary line that separates day from night on earth is called the circle of illumination. It is basically the region that is experiencing sunshine. The circle of illumination cuts all latitudes into half on the spring and autumnal equinoxes.
The circle of illumination is an imaginary line that separates the Earth into two equal parts, creating equal parts of day and night. It passes through the poles and allows the entire Earth to have an equal amount of time spent during the daylight and nighttime hours. Astronauts can see this line even from outer space. The exact location of the line is dependent on the various seasons.
The circle of illumination also plays a small part in the seasons that are experienced. Because the Earth is in a different place on the circle, there are fewer daylight hours. Winter has the least amount of daylight hours, which means that there is less sunlight to help keep things warm. Places on the Earth that are closer to the north and south poles are more affected by the lower amount of sunlight, making winters colder and more intense.
The day is divided into different parts such as morning, afternoon, evening, and night. There is no exact time when each one begins and ends, because they can vary according to your lifestyle and the hours of daylight at each time of year. For example, morning is generally considered to be from 5 am to 12 pm (noon), with early morning being from 5 to 8 am and late morning being from 11 am to 12 pm. Afternoon is from 12 pm to 5 pm, with early afternoon being from 1 to 3 pm and late afternoon being from 4 to 5 pm. Evening is from 5 pm to 9 pm, with early evening being from 5 to 7 pm. Night is from 9 pm to 4 am.
