Final answer:
The statement "Laccoliths form when lava slowly seeps out of the earth, filling a depression or small valley with igneous rock" is false
Step-by-step explanation:
False. Laccoliths form when magma slowly seeps out of the earth and pushes up overlying rock layers, creating domed structures. These structures are formed due to the intrusion of intrusive igneous rocks into the earth's crust. Unlike lava, which cools quickly on the earth's surface and forms extrusive igneous rock, magma cools slowly beneath the surface and forms intrusive igneous rock with larger crystal size.
