Formation
Hawaiite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes and reach the Earth's surface.
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.

More about Hawaiite and Scoria
Here you can know more about Hawaiite and Scoria. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hawaiite and Scoria consists of mineral content and compound content. The mineral content of Hawaiite includes Olivine, Plagioclase, Pyroxene and mineral content of Scoria includes Apatite, Biotite, Calcite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz, Silica. You can also check out the list of all Igneous Rocks. When we have to compare Hawaiite vs Scoria, the texture, color and appearance plays an important role in determining the type of rock. Hawaiite is available in black, brown, light to dark grey colors whereas, Scoria is available in black, brown, dark grey to black, red colors. Appearance of Hawaiite is Dull and Soft and that of Scoria is Glassy and Vesicular. Properties of rock is another aspect for Hawaiite vs Scoria. The hardness of Hawaiite is 6 and that of Scoria is 5-6. The types of Hawaiite are Volcanic rock whereas types of Scoria are Basaltic Scoria and Andesitic Scoria. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Hawaiite is while that of Scoria is white. The specific heat capacity of Hawaiite is 0.84 kJ/Kg K and that of Scoria is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Hawaiite is heat resistant, pressure resistant, wear resistant whereas Scoria is heat resistant, impact resistant, pressure resistant, wear resistant.
