Lines on a weather map that connect points of equal temperature are temperature symbols. station models. isobars. isotherms.

Explanation:

The line that joins the vertices that have the same temperatures in the given time unit are called isotherms. It is very important to know this data since it serves when it comes to building to avoid the deterioration of the structures taking into account the temperatures.

the answer to this question is give me a better question

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.
