Key Differences
Fire is a chemical reaction known as combustion, involving fuel, heat, and oxygen, which results in the release of light and heat. Whereas lava is a physical manifestation of geothermal energy, consisting of molten rock that surfaces during volcanic activity. Both are natural phenomena but result from different processes.
Fire typically occurs at a much lower temperature range, burning at about 600°C to 1,200°C depending on the material and oxygen availability. On the other hand, lava flows at temperatures from approximately 700°C to 1,200°C, showcasing the intense heat generated beneath the Earth’s crust.
Fire emits light and heat, making it a crucial energy source for human use over millennia, for heating, cooking, and industrial processes. In contrast, lava, while also intensely hot, is primarily destructive when it interacts with human-made structures and natural landscapes, reshaping landforms and ecosystems.
The visibility of fire is marked by flames that can vary in color based on the substances being burned and the temperature of the fire. Whereas lava is typically red-hot in its most visible state, cooling to a blackish hue as it solidifies, with its flow patterns often visible on the landscape.
Fire can be quickly started and extinguished with proper tools and techniques, making it manageable under controlled conditions. Lava, however, once it begins to flow, is unstoppable until it cools and hardens, making management about containment and diversion rather than extinguishment.

Fire
Fire is the rapid oxidation of a material in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. Fire is hot because the conversion of the weak double bond in molecular oxygen, O2, to the stronger bonds in the combustion products carbon dioxide and water releases energy (418 kJ per 32 g of O2); the bond energies of the fuel play only a minor role here.
Lava
Lava is molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon. Magma is generated by the internal heat of the planet or moon and it is erupted as lava at volcanoes or through fractures in the crust, usually at temperatures from 800 to 1,200 °C (1,470 to 2,190 °F).
