The Protestant Reformation served as a catalyst for a massive shift in the political make up of Europe.
They did this by taking away the financial base that the Catholic Church was using to centralize power and by taking money away, the Protestant Reformation was able to move power from the Church to the people & lords of each country.
Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered more than the other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.<u>But the true color of the ocean is said to be blue.</u>
