GENERAL KNOWLEDGE

Detailed explanation-1: -The Earth orbits the sun once every 365 days and rotates about its axis once every 24 hours. 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: -Earth rotates because Sun attracts the earth and thus pulls earth towards it secondly due to earths revolution around sun it tends to go away from sun in direction of the tangent hence a rotational force (torque) acts on earth and it tends to rotate.

Detailed explanation-3: -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-4: -Day and night are because of the Earth rotating on its axis. Earth takes one day to rotate one time on its axis. Complete answer: Earth’s rotation: We have day and night because of the reason that Earth rotates or (spins) on an imaginary line known as its axis.
