Igneous rocks. The word ‘igneous’ comes from the Latin word ignis, meaning fire. At plate boundaries, or hot spots, some rocks get heated deep inside the Earth and melt into ‘molten rock’. Molten rock is called magma when it is inside the Earth and lava when it is on the surface.

Igneous rock (derived from the Latin word igneus, meaning of fire, from ignis meaning fire) [9] is formed through the cooling and solidification of magma or lava. This magma may be derived from partial melts of pre-existing rocks in either a planet's mantle or crust. Typically, the melting of rocks is caused by one or more of three processes ...
Jul 9, 2023 · Igneous Rocks. Igneous rocks form from the solidification of magma or lava. The word ‘igneous’ comes from the Latin word ‘ignis,’ which means ‘of fire.’. These rocks fall into two groups based on where the magma solidifies – intrusive and extrusive.
Fire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. [1] [a] At a certain point in the combustion reaction, called the ignition point, flames are produced.
Apr 20, 2022 · A classic example is the flame generated by burning acetylene in oxygen, which reaches an eye-watering 3100˚C. The paltry 1500˚C flame produced by a wax candle, on the other hand, is too low to be considered a textbook plasma.
