SSC MTS EXAM

Detailed explanation-1: -Day and night are due to the Earth rotating on its axis, not its orbiting around the sun. The term ‘one day’ is determined by the time the Earth takes to rotate once on its axis and includes both day time and night time.

Detailed explanation-2: -During rotation, the surface of the earth that faces the sun receives sunlight and have daytime. The other part which is facing away from the sun, have night time.

Detailed explanation-3: -The rotation of the Earth on its axis causes day and night. As the Earth rotates, only one-half of the Earth faces the sun at any given time. The half facing the sun is light (day) and the half facing away from the sun is dark (night).

Detailed explanation-4: -The phenomenon of day and night is due to the rotation of a celestial body about its axis, creating an illusion of the sun rising and setting. Different bodies spin at very different rates, some much faster than Earth and others extremely slowly, leading to very long days and nights.
