Many people decided to move from more rural areas that offered land and space for farming to cities that had factories and offered job opportunities
Answer:
- the first direct detection of gravitational waves came in 2015
- gravitational waves are predicted to travel through space at the speed of light
- the existence of gravitational waves is predicted by Einstein's general theory of relativity
Explanation:
The gravitational waves are waves that are produced by the objects, and depending on the mass of the object they can be stronger or weaker in their influence.
These waves have been in the minds of the scientists for more than a century now, with Einstein predicting them in his theory of relativity. The only problem with these waves was that there was no proof of them. The proof finally came in 2015 when these waves were detected from the first time, with two black holes to be thanked for that as they were the source of them.
These waves are predicted to be able to travel with the speed of light through space when they have small amplitudes.
Human Geography is the answer to the study of people
A) is not the answer because we use nearby resources as an important factor in the site and growth of cities.
B) is not the answer because we need to be able to go and trade with other cities, or countries.
C) is correct because people don't use the prevailing wind direction as an important factor in the site and growth of cities.
D) is not the answer because we need to be able to defend our city or country.

Explanation:
Mauryan empire, in ancient India, a state centred at Pataliputra (later Patna) near the junction of the Son and Ganges (Ganga) rivers. It lasted from about 321 to 185 BCE and was the first empire to encompass most of the Indian subcontinent.
Gupta Empire of Chandragupta II
After gaining power, Chandragupta II expanded the Gupta Empire through conquest and political marriages until the end of his reign in 413 CE. By 395 CE, his control over India extended coast-to-coast. Just like Ashoka, Chandragupta II made Pataliputra the capital of his empire and centralized the government there. He used tribute money from allies to fund government projects and salaries. Unlike Ashoka, Chandragupta did not rely on a network of spies or closely monitor the affairs of foreigners or allies. Instead, he let regions make their own decisions about administration and local governance.
Some scholars have argued that the Gupta empire was a golden age of India. The empire was marked by peace and public safety, and scholars flourished in this environment. Kalidasa, a poet of the time, is considered the greatest poet and dramatist of the Sanskrit language. Aryabhata, who lived during Gupta empire, was the first of the Indian mathematician-astronomers who worked on the approximation for Pi. Vishnu Sharma is thought to be the author of the Panchatantra fables, one of the most widely-translated non-religious books in history.
The Gupta empire ended with the invasion of the White Huns, a nomadic tribe of people from central Asia, at the end of the fifth century CE. Until the sixteenth century, there was no unifying empire; regional political kingdoms ruled India.
