During which month does the Sun appear to rise the highest in the sky for an observer in New York State?
(1) December (3) June
(2) September (4) MarchHigh angle of insolation = more energy = summer
Very cold climates occur at Earth’s North and South Poles because the
polar regions
(1) are usually farthest from the Sun
(2) absorb the greatest amount of insolation
(3) receive the most hours of daylight
(4) receive low-angle insolation
High latitude = low angle of insolation = less energy

In New York State, summer is warmer than
winter because in summer New York has
(1) fewer hours of daylight and receives low angle insolation
(2) fewer hours of daylight and receives high angle insolation
(3) more hours of daylight and receives low-angle insolation(4) more hours of daylight and receives high angle insolation
The diagram shows a model of Earth’s

How does the sun appear to change over these 6 months?
Earth’s 23.5o tilt means over the
course of the year the sun’s angle changes by 47o.(23.5 + 23.5 = 47!)

The diagram shows the altitude of the Sun at solar noon on March 21, as seen by an observer at 42° N latitude.
Compared to the altitude of the Sun observed at solar noon on March 21, the altitude of the Sun observed at solar noon on June 21 will be
(1) 15° higher in the sky (3) 42° higher in the sky (2) 23.5° higher in the sky 4) 48° higher in the sky

How do WE see the path of the sun?
The diagram shows the apparent daily path of the Sun, as
viewed by an observer at a certain latitude on three different days of the year.
On which day is sunrise the farthest North of East?
(1) Dec. 21 (3) June 21
(2) March 21 (4) It was the same on all days
On which day are sunrise and sunset exactly East to West?
(1) Dec. 21 (3) June 21
(2) March 21 (4) It was the same on all days
Draw a line to represent the apparent path
of the Sun from sunrise to sunset at
Buffalo on May 21.

A student in New York State looked toward the eastern horizon to observe sunrise at three different times during the year. The student drew the following diagram that
shows the positions of sunrise, A, B, and C, during this one-year period.
Which list correctly pairs the location of sunrise to the day of the year?
(1) A—June 21 (3) A—March 21 B—March 21 B—June 21 C—December 21 C—December 21
(2) A—December 21 (4) A—June 21 B—March 21 B—December 21 C—June 21 C—March 21
Which diagram represents the approximate location of the Sun at 9 a.m. on March 21?
The diagram represents a
horizon in New York State. Four
positions of sunrise: A, B, C,
and D, on different days of
the year are shown
At which position would sunrise occur on June 21?
(1) A (3) C
