We are flying from San Francisco to Australia. Looking back the last thing we observe of San Francisco is the Golden Gate Bridge. Choose the answer that best explains why the bridge was the last bit of San Francisco that we observed. Group of answer choices

because of the water vapor in the air everything disappeared in the haze. The bridge was the largest structure so we saw it last.

as we traveled away from San Francisco the bridge was the last thing we saw because of large its size.

50 miles out is as far as is possible to see through air.

Since the Earth is a sphere the last thing that was observed was the tallest: the bridge.

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.

i beleive d is the right answer
