How did railroads change the future of the Indian Territory? Give examples that illustrate the impact of railroads on industries, the economy, and culture.

Answers

Answer:

Responses may vary but should include some or all of the following information: Railroads made an immediate impact on the Indian Territory. White settlers discovered new job opportunities on the railroad and in harvesting the territory’s natural resources. American Indian tribes experienced great change as they lost opportunities to continue traditions and as they began to lease land to settlers and companies. Industries grew rapidly as the railroad made it easier to take goods from place to place. In particular, coal mining became an important part of the territory’s economy. Finally, the railroads helped to open the door to more white settlement in the territory as the tribes’ land continued to shrink.

you should obey the law for your own good, if you don't obey the law you could get into some serious consequences, if we obey the law we can get rewarded for example, if you see a person stealing go ahead and punch them in the face and they will stop stealing.

Explanation:

In the pre-colonial period, the predominant literary forms were the popular narrative, due to the fact that the native Indian population was illiterate.

The popular narrative is that which is learned and passed on among a people, which follows local traditions, has no original author and can be modified over time.

Some examples of popular narrative are:

tales, legends and myths.

Therefore, in the pre-colonial period, it is clear that the popular narrative was oral literature, which accompanied the way of life and expression of a people who had no knowledge of formal literature.

Pre-colonial literature aimed to educate and culturally socialize a people by instituting, through its legends and stories, feelings of pride, courage, teachings, the history of a people, etc.

It contains 75% of the atmosphere's mass and 99% of the total mass of water vapor and aerosols.Stratosphere: The stratosphere is the second major layer of Earth's atmosphere, just above the troposphere, and below the mesosphere.Mesosphere: The mesosphere is the third layer of the atmosphere, directly above the stratosphere and directly below the thermosphere. In the mesosphere, temperature decreases as altitude increases.Thermosphere: The thermosphere is the layer in the Earth's atmosphere directly above the mesosphere and below the exosphere. Within this layer of the atmosphere, ultraviolet radiation causes photoionization/photodissociation of molecules, creating ions; the thermosphere thus constitutes the larger part of the ionosphere.Exosphere: The exosphere is a thin, atmosphere-like volume surrounding a planet or natural satellite where molecules are gravitationally bound to that body, but where the density is too low for them to behave as a gas by colliding with each other.

How total was the transformation brought about by the industrial revolution? Did anything of the old world remain? Was there opposition to this transition?

Answers

Answer and Explanation:

Once upon a time, humans were fueled by the animals and plants they ate and the wood they burned. They were aided by their domesticated animals, which used to provide most of the energy to use. Windmills and waterwheels captured some extra points, but there was too little in reserve. All life operated within the flow of energy from the Sun to Earth.

Industrial Revolution began around 1750; everything changed during the Industrial Revolution. People found a different source of energy. That source was fossil fuels coal, oil, and natural gas. However, coal led the way formed underground from plants and animals' remains from much earlier geologic times.

We cannot say that the old world has been wholly diminished, but we are modified according to the industrial revolution. We cannot go back to the ancient world because one cannot imagine life without these facilities.

Imagine earlier generations during their childhood years. How did they move ? How did they communicate? What foods did they eat? So there is no going back to the old world because we are adapted to this new world—y in state-teams.

The industrial revolution transformed economies as nations moved from farming to the creation of industries.

Industrial revolution simply means the process of change from an agrarian economy to an economy that's dominated by industries.

The Industrial revolution was vital in changing the world by transforming economies, businesses, and society. The shifts had a vital impact on the world and still continue to shape the world today.
