Lava from a volcano is hotter than steam from a geyser. Lava can reach temperatures of over 1,300 degrees Fahrenheit, while geyser steam is typically around the boiling point of water, which is 212 degrees Fahrenheit.
All lava is extremely hot, regardless of its color. The color is determined by the mineral content and temperature of the lava rather than its temperature.
Magma is hotter than lava because magma is located beneath the Earth's surface where it is exposed to higher temperatures and pressures compared to lava, which is magma that reaches the surface. As magma rises to the surface and cools, it loses some of its heat energy, resulting in the lower temperature of lava.
pahoehoe is the more smooth lava flows. a'a is the very jagged, sharp lava.
Lava flow can appear as a variety of colors, including shades of red, orange, yellow, and black. The color of the lava is determined by its temperature and composition, with hotter lava typically appearing brighter in color.
