DAY AND NIGHT

 

Because the Earth’s axis is tilted, rays of sunlight are more direct in summer and less direct during the winter.  This causes differences in the amount of daylight and temperature in the seasons.  The Earth is tilted 23.5 degrees on its axis.  The tilt and the orbiting of the Earth around the Sun causes the seasons.

The Sun radiates a tremendous amount of energy and heat. Energy from the Sun is called solar energy. 

Our Earth revolves around the Sun every 365 days to complete one year.  All for seasons will occur during this time span.  Our Earth also rotates around an imaginary axis every 24 hours to complete one full day.  Whenever the part of the Earth that you live on is facing the Sun, it is day and when it is not facing the Sun, it is night.  Our Sun rises in the East and sets in the West.
