SOLAR SYSTEM

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: -Rotation causes the day-night cycle which also creates a corresponding cycle of temperature and humidity creates a corresponding cycle of temperature and humidity.

Detailed explanation-3: -The earth revolves around the sun and rotates around its own axis. The rotation of the earth causes day and night. The part of the earth which faces the sun experiences the daytime whereas the part away from the sun gets no sunlight and hence the night.

Detailed explanation-4: -Variations in the length of day and night time from season to season on the earth’s surface is due to the axial tilt of earth’s rotation axis with respect to its orbital axis.
