Answer:
Contact --  Close to a hot spot
Regional  -- At deep subduction areas.
Dynamic  --   Along a transform  boundary
Impact  --  Near a crater
Explanation:
- Contact metamorphism occurs close to the igneous intrusions and is resultant wot a high temperature and only a small surrounding area is heated by the magma and is restricted to zones surrounding the intrusion.
- The regional metamorphism is large scale metamorphism and is due to the convergence of the continental crust along the tectonic margins. 
- The dynamic metamorphism are associated with the zones of moderate stains fault zones.
- The impact of metamerism is a result of the heat and high pressure and this can lead to the high pressure within rocks.
