How Sunlight hits EarthHow Sunlight hits Earth There are 2 different types of light There are 2 different types of light
rays:rays:
• Direct rays: hit aDirect rays: hit a flat flat surfacesurface
• Indirect rays: hit at anIndirect rays: hit at an angle angle ((slanted slanted surface)surface)
MINI LAB: MINI LAB: Direct vs. Indirect Rays Direct vs. Indirect Rays
Did you change the amount of light Did you change the amount of light coming from the flashlight?coming from the flashlight?
Which rays cover more area (Which rays cover more area (light light more squaresmore squares)?)?
Which rays are stronger (Which rays are stronger (brighterbrighter)?)?
MINI LAB: MINI LAB: Direct vs. Indirect Rays Direct vs. Indirect Rays
Direct and indirect rays both provide Direct and indirect rays both provide the the samesame amount of amount of solar energysolar energy..
Direct rays Direct rays focusfocus the heat on a the heat on a smallersmaller area. area.
Indirect rays Indirect rays spread outspread out the heat the heat over a over a largerlarger area. area.
How Sunlight Hits EarthHow Sunlight Hits Earth If Earth wasn’t tilted, we would get If Earth wasn’t tilted, we would get
the same amount of sunlight all year the same amount of sunlight all year longlong

How Sunlight Hits EarthHow Sunlight Hits Earth BUT…because Earth IS tilted, the BUT…because Earth IS tilted, the
amount of sunlight we get changes amount of sunlight we get changes as we revolve around the sunas we revolve around the sun

The type of rays we get depends The type of rays we get depends on which on which hemispherehemisphere is tilted more is tilted more
towards the sun.towards the sun. NorthernNorthern Hemisphere tilted toward Hemisphere tilted toward
the sun:the sun:
• N.H. gets N.H. gets moremore direct rays ( direct rays (warmerwarmer))• S.H. gets S.H. gets lessless direct rays ( direct rays (coolercooler))

Earth’s tilt also causes the Earth’s tilt also causes the hours hours of daylightof daylight to change throughout to change throughout
the year.the year. The hemisphere that is tilted The hemisphere that is tilted towardtoward

Earth’s tilt also causes the Earth’s tilt also causes the hours hours of daylightof daylight to change throughout to change throughout
the year.the year.
More direct rays + more hours of daylight =More direct rays + more hours of daylight =warmer warmer temperaturestemperatures (summer!) (summer!)
