However, there are a number of hemispheres that have special importance for the discriminating viewer. For instance, if the equator is the great circle enclosing a hemisphere, the viewer will be seeing either the Northern Hemisphere or the Southern Hemisphere. In both cases, the center of the hemispheric view will be one of the poles. For example, South Pole station sits on ice that measures 8, ft 2, m in thickness. The presence of a preponderance of water in the Southern Hemisphere has a great impact of the climate in this region.
Since large water bodies do not heat up and cool as quickly as comparably sized land areas, the annual changes in temperature are much lower. The view of the Northern Hemisphere is distinctly different. At the center of the view is the geographical North Pole, a point that is impossible to permanently mark on the surface because of the constant movement of the ice on the Arctic Ocean.
South of the pole are the northern regions of the great landmasses of the northern hemisphere. Particularly imposing in this regard is the longitudinal sweep of Eurasia extending over degrees of longitude. The climatic impact of the presence of large land areas in the Northern Hemisphere is profound.
The Equator , or line of 0 degrees latitude, divides the Earth into the Northern and Southern hemispheres. There are differences in the climates of the Northern and Southern hemispheres because of the Earth's seasonal tilt toward and away from the sun.
In the Northern Hemisphere, the warmer summer months are from June through September. There are generally considered to be four hemispheres: Northern, Southern, Eastern, and Western. The Equator , or line of 0 degrees latitude, divides the Earth into the Northern and Southern hemispheres. There are differences in the climates of the Northern and Southern hemispheres because of the Earth's seasonal tilt toward and away from the sun.
In the Northern Hemisphere, the warmer summer months are from June through September. In the Southern Hemisphere, summer begins in December and ends in March. The Earth can also be divided into hemispheres along meridians, or lines of longitude. The prime meridian , or 0 degrees longitude, and the International Date Line , degrees longitude, divide the Earth into Eastern and Western hemispheres. Many geographers consider the 20 degree west line of longitude and the degree east line of longitude as the Eastern and Western hemispheres.
This calculation is made so that Africa and Europe are not split. The idea of Eastern and Western hemispheres has become politically and historically significant since European nations began colonizing North America and South America.
Internal Hemisphere The word "hemisphere" is usually used to refer to halves of the Earth, but it is also used to identify the halves of the brain. The brain is divided down the middle into the right and left hemispheres. Each brain hemisphere is considered to be specialized for certain behaviors.
For example, the right hemisphere of the brain controls muscles on the left side of the body, and the left hemisphere of the brain controls muscles on the right side of the body.
The left side of the brain is also dominant for language skills, mathematical calculations, and logic. The right side of the brain is dominant for visual imagery, music, and face recognition.
The Southern Hemisphere experiences a milder climate compared to the Northern Hemisphere and experiences the summer season from December to February and the winter season from June to August.
It has been estimated that more than million people reside in the Southern Hemisphere. Jakarta, Rio de Janeiro, Johannesburg, Sydney, and Melbourne are some of the largest metropolitan areas that are located in the Southern Hemisphere.
The areas that are located in the east of the Prime Meridian and the west of the antemeridian are considered to be a part of the Eastern Hemisphere. Often referred to as the "Oriental Hemisphere" and occasionally in a cultural and geopolitical sense the " Old World ," this hemisphere includes major parts of Europe, Africa, Asia, and Australia.
A part of Antarctica is also located here. The Eastern Hemisphere encompasses a greater land area compared to that of the Western Hemisphere.
