Which of the following statements are examples of “the logic of geography”?
(i) There are cities where there are rivers.
(ii) Cities appear as they are not from six miles above the ground.
(iii) It is easy to understand why valleys are populated.
(iv) It is difficult to understand why humans hate and kill one another.
(v) The earth is round, and it has more sea than land.
Rivers are a source of water and water is necessary for life. From ancient times, humans have been living along the banks of rivers for that reason and many more like the land being fertile etc. So, it fits the logic of geography, that the cities are located near rivers.
