* Earth's Tilt: The Earth is tilted on its axis at approximately 23.5 degrees. This tilt causes the amount of sunlight reaching different parts of the Earth to vary throughout the year.
* Winter Solstice: In December, the North Pole is tilted furthest away from the sun. This means the sun's rays hit the North Pole at a very shallow angle, spreading the energy over a larger area.
* Polar Night: Due to the tilt, during December, the North Pole experiences a period of continuous darkness known as the polar night. This doesn't mean *absolutely* no sunlight reaches the pole, but it does mean the sun is below the horizon for the entire 24-hour period.
Therefore, while the North Pole receives very little direct sunlight during December due to the tilt and polar night, it's not completely devoid of solar radiation. Some scattered light and radiation from the sun can still reach the outer edge of the atmosphere, even during this time.
