Fire is a chemical reaction; it uses oxygen to turn one substance into another. If you cover it, it can't get any oxygen from the air, and so the chemical reaction stops and the fire goes out.
I borrowed the following equation from another online Q&A as an illustration. When propane (carbon and hydrogen) burns, it combines with oxygen to make carbon dioxide (carbon and oxygen) and water (hydrogen and oxygen).

Is it safe to put a candle in sand?
Yes, but the sand might not support the candle very well, and if the lighted candle were to fall over, there might be a fire danger depending upon where it is located and what materials, other than the sand, surround it. Putting a candle in sand at the beach, for example, would be no problem at all even if the lighted candle were to fall over. But putting a candle in a bowl of sand on the dining room table would be risky because if the lighted candle were to fall over it might cause a fire. Of course, if you don't intend to light the candle, putting it in sand is perfectly safe.
