they are logitude and latatude
The equator at 0° latitude separates the Northern and Southern Hemispheres. The prime meridian at 0° longitude separates the Eastern and Western Hemispheres.
northern and southern hemispheres
The two imaginary lines that divide the Earth into hemispheres are the Equator, which divides the Earth into the Northern and Southern Hemispheres, and the Prime Meridian, which divides the Earth into the Eastern and Western Hemispheres.
No, you cannot separate two hemispheres by sucking out the air from between them. The force keeping the hemispheres together is atmospheric pressure acting on the outside of the hemispheres, not the air inside.
The transverse fissure.
It is impossible to separate the Magdeburg Hemispheres because the push of pressure on the outside is not balanced by the push of pressure from within.
Equator
The Earth is divided into four hemispheres - Northern Hemisphere, Southern Hemisphere, Eastern Hemisphere, and Western Hemisphere - based on lines of latitude and longitude. The equator divides the Northern and Southern Hemispheres, while the Prime Meridian and the International Date Line divide the Eastern and Western Hemispheres.
The hemispheres of Earth are divided by the Equator into Northern and Southern Hemispheres, and by the Prime Meridian and the 180th meridian into Eastern and Western Hemispheres.
