INSOLATION:
The INSOLATION (SUNLIGHT) fromthe Sun is the source of Earth’senergy
The Sun gives off the entireElectromagnetic spectrum ofenergy….
Earth gets the visible light and heat(infrared) and a little UV. EveryOTHER light is blocked byatmosphere.
*Angle of insolation: theangle that sunlight hits Earth’ssurface.
The angles of insolation can rangefrom 00 to 900.
Rays that strike at 900 are calledvertical rays (or direct rays).
Very hot & sunny places get insolation(sunlight) at close to a 900 degreeangle.
Very cold places get insolation(sunlight) at much less than 900 degreeangle.
*places with the most vertical sunlighthave the highest temperatures.

Mar. 21: vernal equinox (spring):equator gets vertical rays
June 21: summer solstice : Tropicof Cancer gets vertical rays
sept. 21: autumnal equinox (fall):equator gets vertical rays.
Dec. 21: winter solstice : Tropicof Capricorn gets vertical rays

It takes time for things toheat up.
Even though solar noon has thegreatest angle of insolation1pm to 2pm is the hottest part of theday…
*Even though June has themost insolation.July to August are thehottest part of the year…
It takes time forthings to cool.
even though December gets theleast insolation.This is why January to Febuary isthe coldest time of the year…
*Duration of insolation:1.The length of daylighthours (or how long ittakes the sun to moveacross the sky).
The sun’s apparent path
Everyday the sun appears to rise inthe east, move across the southernsky & set in the west.
On June 21st, the sun’s path is longestduring the summer solstice , so the dayis longest
*ON DEC 21ST, the sun’s path isshortest during the winter solstice, sothe day is shortest.
*The longer the sun’s path, thelonger the day is.What is the longest day inNew York state?What day is theshortest?
the longer the day, the moresunlight an area gets.What is the longest day inNew York state?What day is theshortest?

There are four important days thatyou MUST know….
What day is “A”?
“A” is December 21st because the Sunhas a SHORTEST apparent pathacross the southern sky.
What day is “C”?
“C” is JUNE 21st because the Sun hasa LONGEST apparent path across thesouthern sky.
What TWO days might “B”?
“B” CAN MARCH 21ST ORSEPTEMBER 23RD.
