Reasons for The Seasons.

1. When in it is winter in the northern Hemisphere which areas on earth get the most concentrated light?Which areas get the most concentrated light when it is summer in the northern hemisphere?
whether it is winter or summer in any case the equator get the most sunlight unless it is facing away from the sun.
2.Compare your observations of how the light hits the area halfway between the equator and north pole during winter and during summer?
When we could see the grids i noticed that as the grids get more away from the center where the light is pointing they become more into rectangle then squares. I also noticed that in summer we have longer shadows and in winter we have smaller since the earth is tilted to the right making bigger shadows.
3.If the square projected on the ball from the acetate become larger what can you infer about the amount of heat distributed in each square?
As the squares become rectangle it is showing that the rectangle are showing that there you receive less heat than the places where there are squares.
4.Which areas on earth are consistently coolest and which areas are consistently warmest?why?
The areas on earth that are consistently cold are the ones farther from the equator since they receive less sun light. The coldest places are the north and south pole.
5.What time of the year will the toothpick's shadow be longest?When will the shadow be shortest?
During the summer shadows are long since the earth is tilted to the sun and during the winter it is tilted away from the sun.
6.How are the amounts of heat and light received in a square related to the angle of the sun's rays?
If the angle is different then the amount of heat the earth would get would change since if it is going directly to the north pole there would be perfect square on that but on the rest it would be.
What causes the seasons?
The reason we have seasons is that the earth is constantly rotating and the tilt is changing periodically.

  1. Remember that the reason we have seasons is the tilt. The tilt itself does not change but the revolution of the Earth around the sun puts the northern hemisphere facing the sun which gives us summer. Or away from the sun which gives us winter. You are right about the direct and indirect light. Good job on that.
