Quizplus · Accepted Answer

The given information about the rocks being formed from solidified molten lava indicates that they are igneous rocks. Igneous rocks are formed through the cooling and solidification of molten material, usually magma or lava. Sedimentary rocks are formed from the accumulation of sediments or the cementing of pre-existing rocks, metamorphic rocks are formed from the alteration of pre-existing rocks under heat and/or pressure, and meteoritic rocks are formed from meteorites that have fallen from outer space. However, none of these processes directly involve the solidification of molten lava.
