Explanation / Answer
Answer 1: March, September
See Galapagos and Macapa Island lie on the equator. At equator during the equinox, the sun directly shine over it. We know that equinox occurs during March and September twice in the year
Answer 2: In December
La Serena lies closer to the line of Capricorn, where the sun shines at the higher angle during the winter solstice in the northern hemisphere or you can say at the time of December in the southern hemisphere.
Answer 3: C both are true,
see for July to December solar insolation(amount of radiation ) is high in the northern hemisphere and from December to June, the opposite is happening. Since Ushuaia lie in the southern hemisphere so high insolation is expected in December to June.
Answer 4: a
see sun angle are not exactly same everywhere but almost comparable.
