They're spread around the world... usually along the edges of tectonic plates.
They are spread evenly around the world. Once two or more plates meet together they make an earthquake or volcanoe at anytime.
They are concentrated in zones and are scattered unevenly.
Volcanoes are in concentrated zones.
Volcanoes are more frequent around the "ring of fire", by japan, California, Australia, and Alaska.
They are concentrated in zones - specifically at or near convergent and divergent tectonic plate boundaries. There are a few exceptions that can occur within tectonic plates which are thought to be caused by mantle plumes which create hot spots. An example would be the Hawaiian Island chain which has formed roughly in the centre of the pacific plate.

It is less concentrated than in the USA, but more concentrated than in Europe.

Diffusion is the movement of particles/molecules from a high concentrated area to a low concentrated area until they are evenly spread.
Wealth in Europe is more concentrated, as wealth in all capitalistic countries are (European countries are mainly capitalist).
concentrated in the south
No. They tend to be concentrated at or near the boundaries of tectonic plates.
Wealth is heavily concentrated in Latin America, as the vast majority of people are poor while only a few are immensely rich.
