A tectonic plate boundary, as the name intuitively suggests, is the boundary between two tectonic plates. A tectonic plate boundary can be a convergent boundary or a divergent boundary. Convergent boundaries are hotspots for earthquakes because of the occasional stress release (as energy) as the tectonic plates collide. Towns & cities close to these boundaries are highly prone to destruction by earthquakes and tsunamis.

Answer: A. Geological processes continue over millions of years.
A swamp is a wetland which exhibit the growth of vegetation. It consist of vegetation which is being dominated by trees. When these trees die, the wooden parts sank below the water. The wood remains being deposited at the bottom of the water body causes the formation of coal. Coal formation results due to the wood being compressed and buried. It takes millions of years for the transformation of wood into coal in the geosphere of the swamp region.
Hence, formation of coal is a geological process and it takes millions of years for it's formation.
