Final answer:
Lava is fluid and flows easily, creating a less steep structure. It has low viscosity, allowing it to spread over larger areas and travel further.
Step-by-step explanation:
False. Lava is actually fluid and flows easily, creating a less steep structure. It has low viscosity, which means it is not very thick or sticky. This allows it to spread over larger areas and travel further. Lava flows quickly and can move easily over distances of more than 20 kilometers.
