What is the difference between dusk and dusk?

In order to understand the difference between dusk and dusk, it is important to understand several important terms with regard to the observed movement of the Sun in relation to Earth. There are four terms that are interconnected and help clarify the meaning of "dusk". Dawn is the moment when the light of the sun begins to illuminate the area, although the sun is not visible, and the sunrise is a point in which the sun becomes visible; Sunset is a moment when the sun is no longer visible, and dusk is a point in which the area darkens. Twilight is the time between dawn and east and between sunset and dusk, during which light is dispersed indirectly from the sun to the lighting of the area.

Twilight and dusk are different concepts, even if they are closely connected with regard to the sun moves around the sky. Although Twilight is commonly associated with the West and Twilight, it actually occurs twice a day. In the morning is Dawn mum in which the sun begins to illuminate the sky and dusk is a period of time when the atmosphere is scatteredsunlight that provides indirect lighting. This is followed by sunrise when the sun appears on the horizon in the morning.

At the end of the day there is a similar process that takes place otherwise in which dusk and dusk occur. The sunset is a moment when the sun is no longer visible above the horizon that begins in the evening of the twilight, when the indirect lighting of sunlight is created by the atmosphere. This twilight technically ends in twilight when this light is replaced by darkness. The basic difference between dusk and dusk is because dusk is a period when evening light is still indirectly in the sun, while dusk is when this light disappeared for the night.

timing for dusk and dusk can be affected by number factors. The position of the observer on the ground, with regard to its latitude, may have a direct impact on when twilight and dusk will occur. Seasonal changesY based on the tilt of the Earth can change the twilight time in the morning and evening. There are also three different types of twilight, based on the position of the Sun: civilian twilight occurs when the sun is not visible, but its center is below the horizon less than 6 °; Naval twilight is observed when the center of Sun 6 ° to 12 ° below the horizon is; And astronomical twilight happens because the sun is 12 ° to 18 ° below the horizon.
