In the last 2 days my mac has been getting really hot causing the fan to come on very loudly. What is wrong?

In the last 2 days my mac has been getting very hot causing the fan to come on very loudly. About 20 minutes after it cools enough for the fan to go off, it heats up again. I looked at the Activity Monitor but honestly I didn't know what I was looking for.

MacBook Pro, OS X Yosemite (10.10.3)
