The Earth has been divided into four hemispheres, with lines of Latitude and Longitude in order to enable humans to navigate, reach and know where they were in the vastness of the oceans. Navigation was due mainly to a sextant (and a visible sun) and, eventually, an accurate ship's chronometer (clock). Nowadays, with GPS, and other modern devices, charts on paper are no longer vital, but very important if modern devices suddenly run out of power, or fail!
The four sphere of the earth are the Atmosphere (gaseous envelope), the hydrosphere (water), the lithosphere (crust, mantle), the biosphere (living organisms).
The four inner, rocky planets are also known as the terrestrial planets. These are; Mercury, Venus, Earth and Mars. Of these four, the largest and the most massive is the Earth.
Hydrosphere.
Next after Earth is Mars, then the four "outer planets": Jupiter, Saturn, Uranus, and Neptune.

A sphere is not usually divided into 4 quadrants. Dividing by 2 along each of the 3 orthogonal axes partitions the sphere into 8.
There are several different ways of dividing the Earth. * Northern and Southern hemispheres - dividing it in two through the middle. * Land and Water - water covers 70%+ of the surface of the earth. * Continents - the land is divided into major landmasses, such as Africa, America, Asia, Australia, Antarctica and Europe.
The four hemispheres are called the northern hemisphere, Southern Hemisphere, Eastern Hemisphere, and Westhern Hemisphere.

One quarter of twenty-four is six. This is calculated by dividing twenty-four by four. Therefore, ( 24 \div 4 = 6 ).

A quarter of 42 is 10.5 You can find this by dividing 42 by four.
Dividing by four is just one of many possibilities.
