Which of the following is a characteristic of igneous rock?

Igneous rock is formed by the solidification of molten magma or lava. As a result, it is characterized by a crystalline nature, meaning that it is composed of interlocking crystals that have grown as the magma or lava cooled and solidified. These crystals can vary in size depending on the rate at which the magma or lava cooled. Igneous rocks can have a range of textures, from very fine-grained to coarse-grained, depending on the cooling rate. Therefore, the characteristic of igneous rock is that it is crystalline in nature.
