No need to read the article. It’s literally in the name.

AM = Amplitude Modulation FM = Frequency Modulation

Obviously environmental factors can affect the amplitude of a radio signal. But environmental factors are less likely to affect the frequency.

I don't think that's "obvious" to most people.

And it's not correct. Resulting frequency due to random noise is also changed, but in FM, noise is less perceivable. There is no such thing as "affecting amplitude" and "affecting frequency" - they are not separate concepts.
