How many hemispheres are there




















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 Earth is the only place in the known universe that supports life.

Inversely, summer for the southern hemisphere takes place during the months of December, January, and February because that is when it receives the most direct sunlight. Did you know that the earth is approximately 3. Learn more about the relationship between the earth and the sun with these resources.

About The only ocean that is completely located in this hemisphere is the Arctic Ocean. The other oceans, namely the Pacific , Atlantic , and the Indian Ocean have portions both in the Northern as well as in the Southern hemisphere. This hemisphere includes the entirety of Australia , New Zealand , and Antarctica as well as major parts of South America, about one-third of Africa, and some islands of mainland Asia.

Major portions of the Pacific, Atlantic, and Indian oceans are located in the Southern hemisphere. In addition to this, the only ocean that is entirely located here is the Southern Ocean. 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 prime meridian is the conventional starting point for assigning degree values to longitude lines. The area west of the prime meridian to longitude degrees is the Western Hemisphere. Conversely, the area to the east of the prime meridian is the Eastern Hemisphere.

The longitude lines in both Hemispheres are measured in degrees from the prime meridian. Time zones are also directly related to the degrees of longitude. The time of day increases east of the prime meridian one hour for every 15 degrees of longitude. On the other hand, the time of day decreases west of the prime meridian one hour for every 15 degrees of longitude.

A traveler crossing the International Date Line in an easterly direction and entering the Western Hemisphere would then be in the previous day. On the other hand, travelers going from the Western Hemisphere into the Eastern Hemisphere would find themselves in the next day. Although 18 0 degrees longitude designates the International Date Line, the line is displaced to the west at one point in order to include the Aleutians and keep all of Alaska in the same day. Similarly, the line is displaced to the east in the southern Pacific Ocean to include the Cook Islands in the same day as Australia and New Zealand.

Two additional hemispheric views illustrate the land and water hemispheres. If a globe is oriented so that the Cook Islands in the South Pacific are in the center, the water hemisphere may be seen. This is the hemisphere that has the maximum amount of water in view. In addition to a few islands in the South Pacific, the only land areas visible are portions of Australia, Antarctica , and South America.
