Answer:

What is a weak spot in the crust where molten material comes to the surface?

A volcano is a weak spot in the crust where molten material, or magma, comes to the surface. Magma is a molten mixture of rock-forming substances, gases, and water from the mantle. When magma reaches the surface, it is called lava. When lava has cooled, it forms solid rock.
