An eternal flame is a special kind of fire that never goes out. You know how when you light a candle or a fire, it eventually burns out because it needs more fuel or oxygen to keep going? Well, an eternal flame is designed to never run out of fuel or oxygen, so it can burn forever.
Sometimes, people create eternal flames to remember something or someone important. For example, there are many eternal flames around the world that remember soldiers who have died in wars. The idea is that the flame will keep burning as long as people remember and honor those who have passed away.
Other times, eternal flames are used for religious or spiritual purposes. Some cultures have eternal flames in their places of worship as a symbol of everlasting life or the presence of a higher power.
Eternal flames can be fueled by different things, such as gas, oil, or even natural gas that comes from the ground. To keep the flame going, there are systems in place to make sure the fuel keeps flowing and the oxygen levels stay balanced.
Overall, an eternal flame is a special kind of fire that is designed to keep burning for a very long time, often as a way to honor or remember something important.
