false
Explanation
The statement concerns Earth's geology - the Earth's mantle is mostly solid, not liquid. In simplistic terms, the Earth is composed of various layers: the crust, the mantle, the outer core, and the inner core. The mantle lies directly below the crust and memory tricks often compare it to the mantle of fireplace, offering some structure-support role, which a liquid would struggle to provide. The mantle, in reality, is overwhelmingly solid but can very slowly flow, deforming plastically over geological timescales. Directly below the mantle, the outer core is mainly liquid. It would therefore be incorrect to state that the Earth's mantle is primarily liquid.
