The Earth is divided into two hemispheres: Northern Hemisphere and Southern Hemisphere. The equator serves as the dividing line between the two, with the Northern Hemisphere located above the equator and the Southern Hemisphere located below it.
Yes the earths axis cases the earths its seasons. The tilt determines how much the content is exposed. The higher you will be exposed to less sun which causes it to be cold. Also which the bottom more closer you are to the bottom its cold. There is a imaginary line that splits the earth into two parts. Northern hemisphere and Southern hemisphere. This line is called the equator, everything close to this line is very tropical and hot. The earths axis is determined how far the moon is from the sun which is another question which there is answer.... hope this helped
The name of the line separating China and tibet is McMahon Line.
It appears there may be a typo in your question. If you meant "equator," it is an imaginary line that divides the Earth into the Northern Hemisphere and the Southern Hemisphere. It is located at 0 degrees latitude.

A compass will point the same whether it is in the northern or southern hemisphere. The needle on a compass is designed to magnetically line up with the earths poles. Therefore the north end of the needle of the compass will point to earths north, and the south end of the compass needle will point towards earths south whether you are in the northern or southern hemisphere.
