Detailed explanation-1: -Slate is not an igneous rock, from the above mentioned options.

Detailed explanation-2: -Igneous rocks can be divided into four categories based on their chemical composition: felsic, intermediate, mafic, and ultramafic. The diagram of Bowen’s reaction series (Figure 7.6) shows that differences in chemical composition correspond to differences in the types of minerals within an igneous rock.

Detailed explanation-3: -Detailed Solution. The correct answer is Asphalt.

Detailed explanation-4: -Igneous rocks are defined as types of rocks that are formed when molten rock (rock liquefied by intense heat and pressure) cools to a solid state. Lava is molten rock flowing out of fissures or vents at volcanic centres (when cooled, they form rocks such as basalt, rhyolite, or obsidian).

Detailed explanation-5: -The following would not be associated with igneous rocks: c) Sedimentary rocks. Igneous, metamorphic, and sedimentary rocks are the three major types of rocks that are found in the earth. Igneous rocks are formed from molten rock, or magma, either underground or after magma is released by a volcano and becomes lava.
