Which type of rock is known for flowing smoothly like honey?

• A. Felsic
• B. Mafic
• C. Igneous
• D. Metamorphic

Answer: (B)

The type of rock known for flowing smoothly like honey is mafic rock. Mafic rocks are rich in magnesium and iron, which gives them a lower viscosity compared to other types of rocks, especially felsic rocks. This lower viscosity is due to their basaltic composition, which allows them to flow more easily when molten. When considering volcanic activity, mafic lava, such as that which forms basalt, tends to have a smoother flow, resembling honey in consistency. This is especially evident in shield volcanoes where mafic lava flows can travel great distances due to their fluid nature.

In contrast, felsic rocks, which are rich in silica and aluminum, tend to be more viscous and can lead to more explosive volcanic eruptions. Igneous rocks, while encompassing both mafic and felsic types, do not specifically represent the flowing characteristic unless they refer to the mafic category. Metamorphic rocks, on the other hand, are formed under intense heat and pressure and do not flow like lava; they have typically undergone a transformation from their original rock form rather than being molten. Therefore, the properties of mafic rocks align well with the description of flowing smoothly like honey.
