Why are radio frequencies split into radio waves and microwaves?

I'm doing a project for school on radio frequency and how it is used for communication. However, it has been extremely hard to find any information on why it is split into radio waves and microwaves.

Both radio waves and microwaves are examples of electromagnetic radiation. The split into various categories is somewhat arbitrary. In reality, there's a continuous spectrum of EM radiation and there are no real "hard breaks" between different parts of the spectrum. We group parts of the spectrum together with a specific name because of specific applications.

It's worth noting that radio waves and microwaves are quite close together in the EM spectrum. Depending on who you ask, they may even overlap. But it's all a matter of definition, there is no hard rule.
