a diagram of the Earth and the Sun, when the Earth is facing the Sun it is illuminated and is day. When the Earth is not facing the Sun, it is night. The Earth is also tilted on its axis and polar day at the north pole when facing the Sun is labeled. Polar night when titled away from the Sun is labeled at the South Pole.
How do we experience day and night? When the side of the planet you are on is facing the Sun, you experience day. When the side of the planet you are in is facing away from the Sun, it is night. This means that when it’s day in the United States, it’s night in India on the other side of the planet.
As Earth rotates on its axis, half of it is always facing the Sun. The portion of the Earth that is receiving sunlight is constantly changing as our planet spins. When you are watching a sunrise, you are essentially spinning eastward into the light and the Sun pops up along the horizon. As the day progresses, the Sun will pass across the sky as you continue to spin around until the Sun falls behind the western horizon and out of view.
