Iceland lies on the mid Atlantic ridge.
This is a constructive plate boundary where 2 oceanic tectonic plates are moving away from each other.
Magma is constantly brought to the surface which cools to form igneous rocks.
Obviously the world is not constantly growing with this new addition of crust.
As new crust is created at the ridge, crust at the other end of the plate is destroyed through a process known as subduction.
Like a conveyor belt with production in the middle and destruction at the edges.

What country is not made of mountainous volcanoes?
Generally ones that are composed entirely of cratons that were never on plate boundaries - and they are few. On the other hand there are very few that are entirely volcanic - Iceland and Hawii are two. Most countries, including the UK and France,have at least the remnants of veryold, extinct volcanoes &/or intrusive igneous rocks.
