Answer:

When it gets dark, it is generally in the evening. Darkness is the absence of light, and it occurs when the sun sets and the sky becomes less illuminated. Let's explore this in more detail.

Day and Night:
The Earth rotates around its axis, causing the occurrence of day and night. During the day, the side of the Earth facing the sun experiences daylight, while the opposite side experiences darkness, which is night. This rotation takes approximately 24 hours, resulting in the cycle of day and night.

Evening:
Evening is the time of the day that occurs after the sun starts setting but before it becomes completely dark. It is the period between afternoon and night. During the evening, the sky gradually becomes darker as the sun moves lower in the sky. This is the time when people start preparing for dinner, wind down their activities, and get ready for rest.

Darkness:
Darkness refers to the absence or reduction of light. When the sun sets completely, the sky becomes dark. This is the time when it is difficult to see without artificial sources of light, such as streetlights, lamps, or torches. Darkness is a natural occurrence during the night when the Earth rotates away from the sun, causing the absence of sunlight.

Summary:
In summary, when it gets dark, it is generally in the evening. Darkness occurs when the sun sets and the sky becomes less illuminated. Evening is the time between afternoon and night when the sun starts setting but before complete darkness sets in. It is during this time that the sky gradually becomes darker and people prepare for rest.
