  1. Reason for seasons By Jaclyn Schmitz

  2. Different seasons • Here in Canada we experience four seasons: Winter, Spring, Summer, Fall • Of course, not everywhere has all of these seasons. Places located closer to the equator stay warm all year round (lucky!)

  3. Busted! • A lot of people think the reason why we have seasons is because the earth gets farther and closer to the sun as it revolves around it • THIS IS NOT TRUE! The earth stays about the same distance from the sun all year round

  4. So why do we have seasons? • The reason why we have seasons is because the earth is tilted. • It is tilted at an angle of 23.5 degrees • This means all year long the earth is “pointed” kind of lopsided • The tilt of the Earth means the Earth will lean towards the Sun (Summer) or lean away from the Sun (Winter) 6 months later. In between these, Spring and Autumn will occur. • If the earth was straight up instead of tilted we would not experience seasons the same way

  5. Hemispheres and the seasons • You can tell what season it is in each hemisphere by looking at where the tilted axis is pointing • If north hemisphere is pointed toward the sun, it will be summer in the northern hemisphere, and winter in the southern hemisphere Here the northern hemisphere is getting more direct sunlight since it is pointed toward the sun

  6. Hemispheres and the seasons • You can tell what season it is in each hemisphere by looking at where the tilted axis is pointing • If south hemisphere is pointed toward the sun, it will be summer in the southern hemisphere, and winter in the northern hemisphere Here the southern hemisphere is getting more direct sunlight since it is pointed toward the sun

  7. More information - summer • During the summer, the sun's rays hit the Earth at a steep angle because the sun is higher in the sky. The light does not spread out very much, thus increasing the amount of energy hitting any given spot. The long daylight hours during the summer months allow the Earth plenty of time to reach warm temperatures. This is why the days are hotter in the summer months. • Because the sun is higher in the sky our shadows are shorter than they are in the the other three seasons. http://resources.woodlands-junior.kent.sch.uk/time/seasons.htm

  8. More information - winter • During the winter, the sun's rays hit the Earth at a shallow angle because the sun is lower in the sky. These rays are more spread out, which minimizes the amount of energy that hits any given spot. The long nights and short days prevent the Earth from warming up. This is why we have cold winters. http://resources.woodlands-junior.kent.sch.uk/time/seasons.htm
