What are they?

The earths rotation around the sun, they occur when the earth experiences amounts of daylight. Sunlight hits parts of the earth that causes changes yearly in the climate they are called seasons.

How they change...

  • tilt of earths axis
  • different amounts of sunlight
  • sun rays striking earth
  • earth moves halfway Autumn and spring start to begin

The planets...

1. every planet in the solar system has a season

2. seasons are hardly noticeable

3. northern line is called arctic circle

4. southern line called antarctic cirle

Longest seasons

- Neptune has longest winter

- lasts more than ten years

-Uranus also has longest

- lasts 21 years

-this cause is 23.5 degree of earths rotation

Earth having seasons

If earth was straight up and down there would be no seasons, the earths axis is tilt about 23 degrees.

Also have to do with earth traveling around the sun.

In december southern part tilts toward the sun that's why in the winter the sun doesn't rise

Throughout the year every part of the earth has the same amount of daylight hours, earth at the most extreme is called the solstice.

Earth moving...

Seasons result from earth moving closer and farther away from the sun

orbits the same distance from sun

summer occurs in North/South hemisphere

winter hemisphere tilts away from sun

Other seasons...

  • season's years are distinguished by climate
  • earth's axis is an invisible line
  • Common seasons: Winter, Spring, Summer,Fall/Autumn
  • Lots of cultures have a monsoon season
  • Some people only pay attention to dry and damp seasons
