What is the highest degree of longitude that can be measured? a. 90°w or 90°e b. 90°n or 90°s c. 180°w or 180°e d. 180°n or 180°s

The correct answer is C. 180°W or 180°E

Explanation

Planet Earth with its spherical shape has been divided by imaginary lines to establish geographical locations, climatic zones and time zones. These imaginary lines are the Meridians and Parallels. The meridians are imaginary lines that go from the north pole to the south pole and divide the earth by 360 ° in length; of which 180 ° in length are towards the west and 180 ° in length are towards the east taking as reference point 0 ° the Greenwich Meridian, dividing the earth in eastern and western hemisphere.

On the other hand, the parallels are imaginary lines that divide the earth horizontally taking as reference the line of the equator or 0 °, this pattern divides the earth in the northern hemisphere and the southern hemisphere each with 90 ° latitude. So, the correct answer is C. 180°W or 180°E.

since there isn't any suggested answers i will give you the reason and hopefully you can figure it

south africa, or rather all of africa, has not been in the location in which it is nowadays throughout the geological past. after the super-continent pangaea started to break apart, gondwanaland, in which was africa, moved further south, and parts of it came to be very close to the south pole. because the climate in this part of the world is very cold due to the very dispersed sun rays in there, what is now south africa, started to freeze, and the conditions were right for the formation of glaciers. the glaciers existed up until the period when gondwanaland started to break apart and what is now africa started to move towards north, sp it warmed up and the glaciers melted.
