The rays of the sun strike the Earth less directly during winter in the Northern Hemisphere? Agree or Disagree?

Answer: Agree. During winter in the Northern Hemisphere the rays of the sun strike the Earth at a more oblique angle, meaning less directly. This is due to the tilt of the Earth's axis. Earth is tilted at about a 23.5 degree angle relative to its orbit around the sun. In winter months for the Northern Hemisphere the North Pole is tilted away from the sun. As a result the sunlight that reaches the Northern Hemisphere is spread over a larger area and has to pass through more atmosphere which reduces its intensity and results in cooler temperatures.

Extra: The varying angles at which sunlight hits Earth are what drive the seasons. When the Northern Hemisphere is tilted toward the sun, it experiences summer because the sunlight is more direct, and days are longer. Conversely during winter the hemisphere is tilted away from the sun leading to indirect sunlight and shorter days. The sun's rays are most direct at the equator, which is why tropical regions near the equator experience relatively stable warm temperatures year round and do not have the same distinct seasons as regions farther north or south. The concept of the Earth's tilt and its impact on the seasons is a fundamental aspect of Earth science and is essential for understanding how and why weather patterns and climates vary across the globe.
