The coldest places on earth are found near the poles because of the tilt of the earth's axis. The poles receive less direct sunlight and therefore have colder temperatures compared to other regions on earth. Additionally, the polar regions are covered in ice and snow, which reflects sunlight and further contributes to the cold temperatures. The lack of vegetation and urban development also means there is less heat retention in these areas.

The poles are the coldest places on Earth because:
- Earth's Axis of Rotation: Earth is tilted on its axis by about 23.5 degrees. This causes different parts of the planet to receive varying amounts of sunlight throughout the year.
- Distribution of Sunlight: The poles are located at the ends of the Earth's axis, meaning they receive the least amount of direct sunlight. The sun's rays hit the Earth at an angle near the poles, spreading the same amount of sunlight over a larger area, resulting in less energy per unit area.
- Low Sun Angle: During winter, the sun barely rises above the horizon near the poles. The low sun angle further reduces the amount of sunlight reaching the surface.
- Ice and Snow Reflection: The polar regions are covered in vast amounts of ice and snow. These highly reflective surfaces bounce most of the incoming sunlight back into space, further cooling the surface.
- Air Circulation: Cold air near the poles sinks and flows toward the equator, creating a cold low-pressure zone known as the polar vortex. This vortex traps cold air and prevents it from spreading to other regions.
- Ocean Currents: Ocean currents also contribute to the coldness of the poles. Cold water from higher latitudes flows towards the poles, further cooling the surrounding areas.
- Distance from the Sun: The poles are the farthest points from the Sun, receiving less solar radiation than the equator.
These factors combine to create extremely cold temperatures, especially during the long polar winters when there is little to no sunlight for months.
