The northern hemisphere is a geographical division of the Earth that lies between the equator and the North Pole. It comprises the half of the planet that is located north of the equator. The northern hemisphere encompasses a wide range of landmasses, including the continents of North America, Europe, and Asia, as well as parts of Africa and South America. It is bordered to the south by the equator, which marks the dividing line between the northern and southern hemispheres.
Seasonal variations in the northern hemisphere are quite distinct, as it experiences four distinct seasons - spring, summer, autumn, and winter. These seasons are determined by the tilt of the Earth's axis relative to its orbit around the sun. During summer in the northern hemisphere, the region receives more direct sunlight, resulting in longer days and warmer temperatures. In contrast, winter sees shorter days and cooler temperatures due to the indirect angle of the sun's rays.
The northern hemisphere is home to diverse ecosystems and climates, ranging from the cold and snowy Arctic regions to the temperate forests, vast grasslands, and deserts. It is also highly populated, with numerous countries and significant human settlements. The region boasts various natural landmarks, cultural heritage sites, and important cities. The northern hemisphere plays a significant role in global weather patterns, climate changes, and environmental processes. It is home to some of the world's major industries, economic hubs, and centers of innovation and technological advancements.
The word "northern" originated from the Old English word "norþerne", which meant "located in the north". It is derived from the Proto-Germanic word "nurþrōną".
