The is called "lava", before it comes out on the surface it is called "magma".
Decreasing the pressure will not produce liquid rock below the surface.
"Hot liquid rock" exposed at or above the surface is called lava whereas if it is below the surface it is called magma.
The term "wetting" has a specialized meaning in surface chemistry. We usually say that a liquid "wets" a surface if the contact angle a droplet of the liquid makes with the surface is less than 90 degrees, and that it "doesn't wet" a surface if the contact angle is 90 degrees or more.
Once magma has reached the surface, it is refered to as lava.
