The seasons affect the amount of sunlight the Earth receives due to its axial tilt. During the winter months, when a hemisphere is tilted away from the sun it receives less sunlight and the nights are longer. This also reduces the temperature due to less solar radiation reaching the ground.
While most areas experience longer nights during the winter, areas near the poles can actually experience polar night: a night time that lasts more than 24 hours. This happens due to some locations being tilted so far away from the sun, that the Earth blocks all light for an extended period. The city of Kiruna, Sweden is known for periods of extended darkness that can last up to 28 days.Learn More
The changing tilt of Earth on its axis causes days to become shorter and nights to become longer during winter, and the tilted hemisphere is colder due to the sun hitting the Earth at an oblique angle. North of the equator, winter occurs when the northern hemisphere tilts away from the sun, while the opposite tilt leads to winter in the southern hemisphere.Full Answer >

Clouds are visible concentrations of small water or ice particles that form through the condensation of water vapor. Clouds are classified based on their appearance and their distance from the ground. Some clouds bring rain and snow while others just visually sit in the sky and produce no precipitation.Full Answer >
Cumulonimbus clouds are the tallest clouds in the sky, reaching well into the troposphere. Although the bottom of a cumulonimbus cloud contains water, the top of the cloud reaches so high that it contains ice crystals.Full Answer >
