Which of the following pairs are characteristics of igneous rocks? They
I. are stratified
II are metamorphosed rocks
III. are crystalline
IV. originate from molten magma

Answer Details

The characteristics of igneous rocks are that they are crystalline and originate from molten magma. Igneous rocks are formed by the solidification and cooling of molten magma or lava. During the cooling process, minerals in the magma begin to crystallize and form a solid rock. This is why igneous rocks are typically made up of interlocking crystals. Stratification refers to the layering of sedimentary rocks, which is not a characteristic of igneous rocks. Metamorphic rocks are rocks that have undergone a change in texture, mineral composition, or both due to heat and/or pressure, and are not necessarily related to igneous rocks. Therefore, the correct pair of characteristics for igneous rocks is III and IV only.
