34. What is true during winter in the northern hemisphere?
Answer: C
The northern hemisphere is tilted away from the sun.
During winter in the northern hemisphere, the region is tilted away from the sun, resulting in shorter days and lower temperatures. This axial tilt is responsible for the seasonal changes experienced throughout the year.
A) Earth's distance from the sun is greatest.
While it is true that Earth's distance from the sun varies throughout the year, this does not directly correlate with the winter season. In fact, the Earth is closest to the sun (perihelion) in early January, which occurs during winter for the northern hemisphere, making this option incorrect.
B) The northern hemisphere is tilted toward the sun.
This statement is incorrect because during winter, the northern hemisphere is actually tilted away from the sun. When the hemisphere is tilted toward the sun, it experiences summer, characterized by longer days and warmer temperatures.
C) The northern hemisphere is tilted away from the sun.
This statement accurately describes the position of the northern hemisphere during winter. The tilt away from the sun leads to decreased solar energy, resulting in colder weather and shorter daylight hours.
D) Earth's tilt is at its smallest value.
This option is misleading as Earth's axial tilt remains relatively constant at about 23.5 degrees throughout the year. The angle does not change significantly to be considered "at its smallest value" in winter, making this option incorrect.
Conclusion
The correct answer, that the northern hemisphere is tilted away from the sun, explains the colder temperatures and shorter days associated with winter. The other options either misrepresent the relationship between Earth's distance from the sun and seasonal changes or incorrectly describe the orientation of the northern hemisphere during this season. Understanding this axial tilt is essential to grasping the fundamental concepts of seasonal variations.
