How do you make money from liquidity pool?

I'm curious to understand how one can generate profits from liquidity pools in the cryptocurrency world. Could you elaborate on the mechanics behind it? Do liquidity providers earn through trading fees, interest payments, or some other mechanism? I've heard about the potential for high returns, but I'm unclear on the specific strategies and risks involved. What are the key factors to consider before deciding to participate in a liquidity pool? Your insights would be greatly appreciated.
