Is lava a source of light?

Yes, lava can be considered a source of light. When molten rock erupts from a volcano, its high temperatures cause it to glow brightly, emitting visible light, especially in shades of red, orange, and yellow. This luminescence is due to the intense heat of the lava, which can exceed 1,000 degrees Celsius (1,832 degrees Fahrenheit). Thus, both the thermal energy and glowing appearance of lava contribute to its role as a natural light source.
