Lesson 2 Assessment: Seasonal Sunlight
1. The longest day of sunlight in the Northern Hemisphere occurs on the autumnal equinox.
A. true
B. false
2. Which Earth surface would most likely absorb the greatest amount of insolation on a sunny day if all of these surfaces have equal areas?
A. blacktop parking lot
B. white sand beach
C. surface of a calm lake
D. snow covered mountain slope
3. Use the diagram below to answer to questions 3 through 6. The diagram illustrates Earth orbiting the Sun. Four positions of Earth in its orbit are labeled
A, B, C,
and
D
. Letter
N
represents the North Pole. Distances are indicated for aphelion (Earth’s farthest position from the Sun around July 4) and perihelion (Earth’s closest position to the Sun around January 3). Arrows indicate the direction of movement.
During which season in the Northern Hemisphere is Earth at aphelion?
A. winter
B. spring
C. summer
D. fall
4. Between which pair of lettered positions is the Sun’s vertical ray moving from the equator southward to the Tropic of Capricorn?
A. points A and B
B. points B and C
C. points C and D
D. points D and A
5. Approximately how many times does Earth rotate as it moves in its orbit from position
A
back to position
A
?
A. 1 time
B. 15 times
C. 24 times
D. 365 times
6. What is the tilt of Earth’s rotational axis relative to a line perpendicular to the plane of Earth’s orbit?
A. 15°
B. 23.5°
C. 66.5°
D. 90°
7. Which observation provides the best evidence that Earth orbits the Sun?
A. The Sun has a cyclic pattern of sunspot events.
B. The Sun appears to rise and set in a cyclic pattern.
C. The constellations that can be seen at night from Earth change with the seasons.
D. The constellations appear to move in a circular pattern around Earth.
8. Use the diagram below to answer to questions 8 through 9. The diagram represents Earth’s orbit around the Sun. Positions
A, B, C,
and
D
represent Earth’s location on the first day of each season. Letter
N
indicates the North Pole.
Earth revolves around the Sun at the rate of approximately:
A. 1° per day.
B. 360° per day.
C. 15° per hour.
D. 23.5° per hour.
9. Which graph best shows the hours of daylight that occur
at the equator
on all four Earth positions shown?
A.
B.
C.
D.
