Northern Hemisphere
Definition
In geography, the Northern Hemisphere is the half of the Earth that is north of the equator. It is the larger of the two hemispheres, covering about 67% of the Earth's landmass.
The Northern Hemisphere is home to some of the world's most populous countries, including China, India, and the United States. It is also home to some of the world's most diverse ecosystems, including forests, deserts, and mountains.
The Northern Hemisphere has a variety of climates, ranging from the frigid Arctic to the tropical rainforests of South America. The climate in the Northern Hemisphere is also affected by the seasons, with warmer weather in the summer and cooler weather in the winter.
The Northern Hemisphere is important for many reasons. It is home to a large number of people and it is also home to some of the world's most important natural resources. The Northern Hemisphere is also a major centre for trade and commerce.
How can the word be used?
The Northern Hemisphere contains about 68% of the Earth's landmass.
Different forms of the word

AQA Science Exam Question and Answer
Question:
Explain the concept of the Northern Hemisphere and how its climate patterns differ from the Southern Hemisphere.
Answer:
The Northern Hemisphere refers to the half of the Earth that lies north of the Equator. It includes continents like North America, Europe, Asia, and parts of Africa. The concept of the Northern Hemisphere is significant in understanding global geography and climate patterns.
Climate patterns in the Northern Hemisphere differ from those in the Southern Hemisphere due to several factors. One of the primary reasons is the tilt of the Earth's axis. Because of this tilt, the Northern Hemisphere experiences distinct seasons, including summer, autumn, winter, and spring. These seasons are characterised by variations in temperature, daylight hours, and weather conditions.
During the Northern Hemisphere's summer, the region tilted towards the Sun receives more direct sunlight and experiences warmer temperatures. In contrast, during its winter, the region tilted away from the Sun receives less direct sunlight, resulting in colder temperatures. This seasonal variation influences climate, vegetation, and even human activities.
In the Southern Hemisphere, the opposite patterns occur due to the same tilt. While the Northern Hemisphere experiences summer, the Southern Hemisphere experiences winter, and vice versa. This leads to an interesting contrast in climate zones, weather patterns, and ecosystems between the two hemispheres.
