How does the angle of the sun's rays at noon affect seasonal temperatures?

Question

Im doing an science experiment. Please tell me an example of a science experiment that has to do this the question. Thanks

Answer 1

It is mostly to do with the angle of incidence of sunlight.

At the equator (within the Tropics) the sun gets very high in the sky at noon - and so the sunlight as it hits the ground is most concentrated.

At high latitude, the sun doesn’t get high, the a beam of sunlight comes in at an oblique angle and the sunlight is spread out over a larger area and is thus more dilute.

Try using a laser pointer and shine the spot directly onto the floor, then try holding the pointer at an angle so the spot gets smeared out. The same amount of energy per sec is emitted by the laser pointer in both cases, but when the spot is smeared out the same energy is spread over a larger area, so it wouldn’t get as heated

This effect also accounts for seasons since the sun is high in summer, the light isn't spread out so much.

Answer 2

During the summer, the sun angel is higher than during the winter.  When the sun is higher, it has more heating power as more heat is concentrated in a smaller area.  That is why summers are warm.  During the winter, the sun is lower and the heat is spread out over a larger area.  Since there is less heat per square unit, the air is colder.  It also depends on what part of the world you are on.  On the equator, the sun shines straight down, and the climate is hot.  In the polar regions, the sun shines low, even during the summer, making the places very cold.  There are other influences that control temperature.  Places near the water have a milder climate since the water can store a lot of heat.  Interior locations have more extreme temperatures, since the soil tends to gain and release heat more quickly.  

Let's say the sun is high in the sky and you have two pieces of paper.  Lay one down, so the sun shines directly down on the piece of paper.  Tilt up the other so the sun shines on it at an angle.  You will notice that the flat paper gets hotter since more of the sunlight is concentrated per unit.  The tilted paper have sunlight spread out over a larger unit, making the paper feel cooler.  I believe that explains the angle of the sun and the temperature.  

Answer 3

The Earth is tilted at 23*.  Sometimes that tilt on the Northern Hemisphere is towards the sun, sometimes away from the sun - can you guess which seasons that covers?  It's the opposite in the Southern Hemisphere.  

I guess no one else has an answer for you.  Here's a couple of  links to sites that have some pictures of the Earths tilt and explains it a bit more.  Do a web search and you'll find more.

Good luck.
