Question

the chart below shows the length of daylight (in hours) in the northern hemisphere. the chart includes three different latitudes and four different times of year.which statement best explains the change occurring at 90°n latitude between june and september?choose 1 answer:day length is becoming longer because spring is approaching.day length is becoming shorter because spring is approaching.day length is becoming longer because fall is approaching.day length is becoming shorter because fall is approaching.

Explanation:

• At \(90^{\circ}N\) (the North Pole), on June 21st, there are 24 hours of daylight (summer solstice in the Northern Hemisphere).
• On September 21st (autumnal equinox), there are 12 hours of daylight.
• As we move from June (summer) to September in the Northern Hemisphere, fall is approaching.
• As fall approaches in the Northern Hemisphere, the days get shorter at higher latitudes like \(90^{\circ}N\) because the tilt of the Earth's axis causes the Northern Hemisphere to receive less direct sunlight over time.

Answer:

D. Day length is becoming shorter because fall is approaching.
