Answer:
1) identify one cause of the historical development depicted in the map
A cause of the historical development depicted in the map (the industrial revolution) was the discovery of large sources of coal in Northern England, which were not very deep, something that made them relatively easy to dig out.
This coal provided a significant source of energy to the factories that would be established in the following years.
2) identify one effect of the historical development depicted in the map
An effect of the industrial revolution was the fast growth of several cities in Northern England, which had been, up until that time, small villages. These cities grew because hordes of workers from the countryside emigrated there to work in the factories.
The main cities that grew around the time of the Industrial Revolution are: Manchester, Liverpool, Birimingham, Leeds, Sheffield, New Castle, and Middlesbourgh.
