The correct answer is - B. large empires developed.
The mountains are a natural barrier for lot of human activities, and one of those is the formation of settlements, big countries, or empires. The creation of large empires on a mountainous terrain is extremely hard and unpractical, and there's very few cases in the human history that that has been performed well. The reasons for that is that in the mountainous regions it is hard to create a network of roads, build large settlements, and also there's lack of natural resources and food, so the people had the tendency to create small settlements, or city-states in this kind of circumstances.
Answer:
Global atmospheric pressure and wind patterns
Explanation:
It is a circulation of large scale movements of air mass over the earth by the means of solar energy. Wind belts are also connected to this pattern of air flow between high and low pressure belts like the Hadley, polar, and ferrel cells both in northern and southern hemisphere. the ITCZ area i.e the equator drives most of these winds and as result the warm air rises and colder air which is heavy descent thus leading to the formation of clouds which in turn is also impacted by the sun rays and spinning of the planet differently in northern and southern hemisphere. For example, as the warm current like japanese black or Kuroshio raise temperature in polar area's thus affecting the temperature extremes of the that area indirectly impacting the precipitation around the globe.

Answer:
In order to deposit 100 meters of limestone layer, it will take 6,451,600 years
Explanation:
Given that,
The rate of deposition carbonate sediments is 1.55 cm in 1,000 years
⇒ 1.55 cm = 1,000 years
⇒ 1 cm = 
⇒ 1 cm = 645.16 years
∵ 1 m = 100 cm
∴ 100 m = 100 × 100 cm
⇒ 100 m = 10,000 cm
So, the time it will take for carbonate to deposit 100 m thick layer of limestone will be-
⇒ 10,000 cm (100 meter) = 645.16 × 10,000 years
⇒ 100 meters = 6,451,600 years
