What were four causes of the Scientific Revolution?

The Scientific Revolution occurred in the sixteenth and seventeenth centuries, leading to the Enlightenment. 

In the sixteenth century, Copernicus stated that the earth revolved around the sun. This was the beginning of the “heliocentric” view of the universe. This was a shocker for just about everybody. It shook the religious world to its roots. Previously, it had been assumed that everything revolved around the Earth, and that it did so because God wanted it to. To say that the Earth instead revolved around the sun was considered heresy by some. Once this barrier was broken, scientific progress continued to be made. Galileo confirmed Copernicus' theories in 1610 and added more new information about the planets.

The Protestant Reformation broke the hold of the Catholic church in some places. It began in 1517 with Martin Luther's 95 Theses. Some credit this religious change with making some degree of scientific progress more likely than would have been possible under Catholicism, although this viewpoint is debated. Martin Luther himself was not particularly supportive of any scientific ideas that were not supported by the Bible. 

The Renaissance brought back ancient scientific texts that had been more or less “lost.” These texts generated more interest in science and also gave scientists a better starting point than would have been possible without the revived texts.

The invention of the printing press in 1448 greatly facilitated the flow of information. Now scientists could learn of each other's experiments and observations much more quickly than they could have previously, when everything had to be handwritten, a slow and expensive process.

Later, of course, the Scientific Revolution was crowned by Newton's Laws, which provided a new way of looking at the universe, as a place that followed strict scientific laws that could be discovered and described.
