If you watched the opening ceremony for the Summer Olympics from Tokyo this morning you saw those famous Olympic rings a lot. But what do they actually symbolize?
The five Olympic rings are meant to represent the five continents in the world. Those specific colors (blue, yellow, black, green, red) were chosen for the rings because they all appear on the flags of all the competing nations around the world. Pretty neat!
