Angle of Insolation Flashlight Activity

As the angle of light decreased (when you started to angle the flashlight closer to the paper) what happened to the size of the circle of light?

• The size of circle of light increased.

• The size of the circle of light decreased

• There was no change in the circle of light.

Imagine you drew a dot on the paper. At which angle would the dot receive the most intense amount of light?

• 90 degrees (shown as A in the image)

• 60 degrees (shown as B in the image)

• 30 degrees (shown as C in the image)

Imagine you drew a dot on the paper. At which angle would the dot receive the LEAST intense amount of light?

• 90 degrees (shown as A in the image above)

• 60 degrees (shown as B in the image above)

• 30 degrees (shown as C in the image above)

At which angle would the imaginary dot on the paper be warmed the MOST by the flashlight?

• 90 degrees, as shown by A in the image.

• 60 degrees, as shown by B in the image.

• 30 degrees, as shown b C in the image.

At which angle would the dot be warmed the LEAST by the sunlight?

• 90 degrees (shown as A in the image)

• 60 degrees (shown as B in the image)

• 30 degrees (shown as C in the image)

Where on Earth does the sunlight hit the surface at an average angle of 90 degrees?

• Alaska

• Florida

• Equator

Where on Earth does the sunlight hit the surface at an average angle of 60 degrees?

• Alaska

• Florida

• Equator

Where on Earth does the sunlight hit the surface at an average angle of 30 degrees?

• Alaska

• Equator

• Florida

Why is the atmosphere warmer near the equator?
