Locate the state boundary between Nebraska and Iowa along the Missouri River. Why does the boundary depart from the river channe
Kipish [7]

Answer:

The original boundary between the states of Nebraska and Iowa was the Missouri River.  The border departs from the river channel because the river's course moved eastward many years after the boundaries were established.

Explanation:

The boundary between Nebraska and Iowa was the Missouri River. In 1877, the river course moved, and a town called Carter Lake on the Iowa side is now on the Alaska side. Even though Alaska claimed the land, the Supreme Court stated that the area belongs to the state of Iowa. That is why the boundary departs from the river channel.

Which of the following are correct statements about the Indian subcontinent
CaHeK987 [17]

The subcontinent has fewer natural barriers to invasion than East Asia.

There are lot of educated people in India who are fluent in English.

Explanation:

The Indian subcontinent and East Asia are both regions in Asia. They border with each other, with the border being on the northern part of the Indian subcontinent and southwestern part of East Asia. These two regions have lot of differences between them, including culture, languages, religion, lifestyle, politics, geography etc., but they also have several similarities too.

One similarity of these two regions is that both of them have natural barriers, which throughout history have helped a lot in their protection. The Indian subcontinent has only two natural barriers, the Himalayas, which are massive and occupy almost the entirety of the northern part of the region, and the ocean. East Asia has multiple natural barriers, including the Himalayas, Taklamakan Desert, several seas, and the taiga.

One big difference between the regions is that in India there are much higher percentage of educated people that are fluent in English than in East Asia. This is mostly because India is a former British colony, so the English language is a legacy from the colonialism, but it is also seen as advantageous when looking for jobs.
