Igneous rocks form by the cooling & crystallization of hot, molten rock (magma & lava). If this happens at or near the land surface, or on the seafloor, they are extrusive igneous rocks. If this happens deep underground, they are intrusive igneous rocks. Most igneous rocks have a crystalline texture, but some are clastic, vesicular, frothy, or glassy. Volcanic tuffs have the same origin as volcanic breccias - explosive volcanic eruptions. Volcanic tuffs lack the abundance of large, angular grains present in volcanic breccias (although I
