WebAnswer: 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. WebLava is a hot, molten rock that is expelled from volcanoes. It is made up of several elements, including silicon, oxygen, aluminium, magnesium, and iron.
