In what way did china isolated geography contribute to its development as a country?

Isolation allowed China to develop on its own, without too much interference from foreign invasion.

Explanation:

Even though nomadic invaders came and sometimes took over, they ended up joining and adopting the Chinese cultures and ways.

"More often, the outsiders whom the Chinese encountered were nomadic invaders. To the Chinese, these nomads were barbarians who did not speak Chinese and lacked the skills and achievements of a settled society. Nomads conquered China from time to time, but they were usually absorbed into the advanced Chinese civilization.

Long distances and physical barriers separated China from Egypt, the Middle East, and India. The isolation contributed to the Chinese belief that China was the center of earth. These beliefs in turn led the ancient China to call their land Zhongguo (jahng gwoh), or the Middle Kingdom. To the west and southwest of China, brutal deserts and high mountain ranges-the Tian Shan (tyen shahn) and the Himalayas-blocked the easy movement of people. To the southeast, thick rainforests divided China from Southeast Asia. To the North awaited a forbidding dessert, the Gobi. To the east lay the vast Pacific Ocean.

The ratio of blue marbles to red marbles is 35:15. To test his hypothesis in the best way, he should make sure that the total number of marbles he draws is 100. In other words, both sides of the ratio added together should equal 100. Right now, both sides equal 50 (35 + 15 = 50). To get to 100, double both sides of the ratio. Now, the ratio is 70:30. Based on the 50 marbles Sam drew, there are 70 blue marbles and 30 red marbles, meaning Sam's hypothesis is incorrect, and there are more blue marbles than red.
