How do Seasons Work?


­­­­­How do Seasons work?

 
The seasons are marked with a particular weather pattern, there are 4 seasons summer, winter, autumn and spring. Each of them are 3 months.
 
Earth’s orbit around the sun creates the seasons. One full orbit around the sun is 3651/4 days, as a result of the earth taking one quarter more of a day this makes it that every 4 years we have a leap year. A leap year adds one more day in the year that day is on February 29th.

Earth is tilted 23.5o on its axis. Some people say that this happens because in the early times there were lots of rocks in space so one big one might have hit the earth and shifted it of its axis. Some people also think that the rock that hit the earth made the moon. Overtime lots of small rocks have hit the moon and created all the craters and holes. Of course none of this is proved and it is all theoretical.

The earths tilt creates the seasons. When the sun is pointing directly at one hemisphere of the earth it creates summer. Other seasons are created when the sun is pointing to other points of the earth. At the North and South Pole there is only 2 season’s, summer and winter, In Summer time the sun never sets and in winter the sun never rises, this is due to the earths tilt.

If seasons didn’t exist the earth would not be the way it is today. According to Don Attwood, an ecological anthropologist at McGill University in Montreal, “humans would probably never have advanced past a state of living in small, scattered settlements, scrounging for survival and often dying of horrific insect-borne diseases”.

  1. Your title was clear and to the point. I thought your introduction was especially good. Your have included most of the required features of an explanation but there were no diagrams to support your text! You need to ensure careful proof reading, especially for punctuation. I thought your conclusion was the best that I read - the use of the quotation was very powerful. Well done!
