OA is B -The figure shows a normal distribution with mean m and standard deviation d, including approximate percents of the distribution in each of the six regions shown. For a population of 800,000 subway riders, the numbers of subway trips taken per rider last January are approximately normally distributed with a mean of 56 trips and a standard deviation of 13 trips. Approximately how many of the riders took between 30 and 43 trips last January?

The 1960s was marked by the cold war between the two super powers of the World, Russia and the United States. These countries were often represented as Blue and Red on a map, blue signifying the United States and it's ally countries and Red signifying communist Soviet Union and it's allies around the world. If someone from the Soviet Union would look at the map, they would be nervous to see American Allies all around the world, including Western and Northern Western European countries, some of which were at a close distance to Moscow. On the other hand, if an American looked at the world map, they would see a Giant red Soviet Union covering all of Northern Asia and Eastern Europe. They would also see other communist countries including Cuba, where the Soviets even placed Nuclear weapons, targeted at the United States.

There are different reasons why things happens. If differential heating did not occur on earth, then there no global warming or global cooling will take place in the atmosphere.
When the Earth flat surface is facing the sun, all its part of that surface would get the same level of incoming solar radiation but the fact remains that due to the Earth being spherical in shape, sunlight is therefore not distributed evenly over the Earth’s surface and as such all the regions of Earth will be heated to different degrees.
Thus, differential heating of Earth’s surface takes place due to different reasons.
