POLAR CIRCLE Meaning and
Definition
-
The polar circle is an imaginary line encircling the Earth at a specific latitude, located near both of Earth's polar regions. It is defined as the latitude approximately 66.5 degrees north of the Equator in the Northern Hemisphere and 66.5 degrees south of the Equator in the Southern Hemisphere.
In geographic terms, the polar circle marks the boundary beyond which the phenomena of the polar day and the polar night occur. The polar day refers to a continuous period of 24 hours of daylight, while the polar night refers to a period of total darkness lasting for 24 hours. These phenomena occur because at this latitude, the tilt of the Earth's axis causes the Sun to either stay above or below the horizon for a full day depending on the time of year.
This geographical demarcation line is crucial for understanding the unique climate and natural phenomena experienced near the Earth's poles. It separates the regions where the Sun remains visible above and below the horizon for extended periods, bringing distinct weather patterns and extreme temperature variations.
The polar circle holds considerable significance for scientific research, particularly in the fields of meteorology, astronomy, and ecology, as it influences the behavior of weather systems, celestial observations, and the distribution of flora and fauna. It is often used as a reference point for mapping and determining locations within the polar regions.
