Do I need a visa to be in europe for 3 months and 2 weeks?

I'm going to Europe I leave February 28th and coming back June 10th. I will be traveling/staying mainly in Germany, but also traveling to Norway, Czech Republic, Ireland, England, Spain, Morocco, Greece, France, Italy, Malta, Monaco, and Portugal. So, do I need a visa to do this? Or what is required besides my pport. Also I will be flying to most of these countries once in Germany so will they often check if I have a visa or something because they're more vigilant in airports?
