Volcanism at Nyiragongo is caused by the rifting of the Earth's crust where two parts of the African Plate are breaking apart. >>> breaking apart = divergent = constructive !!!!

The Nyiragongo volcano is located in the African Rift Valley, which is most definitely a CONSTRUCTIVE plate margin, despite the answer (and web-link) from Steven above. The rift valley is forming where two plates are spreading apart, with new crust being created along the rift. Geo06's answer is the correct one!
Interestingly, this volcano is unique in having lava that flows very fast, as fast as a river flow, on account of the extremely basic (i.e. non-siliceous) mineralogy.

Constructive or Divergent. The formation of the Rift Valley continues, probably driven by mantle plumes and ultimately a result of the African superswell. The associated geothermal activity and spreading at the rift has caused the lithosphere to thin from a typical 100 km thickness for continents to a mere 20 km. Though it is common for one arm of a triple junction to fail, if spreading continues the lithosphere may rupture several million years hence, splitting eastern Africa off to form a new landmass. In short, this will lead to the formation of a new mid-ocean ridge.
The volcanic activity at this site and unusual concentration of hotspots has produced the volcanic mountains Mount Kilimanjaro, Mount Kenya, Mount Karisimbi, Mount Nyiragongo, Mount Meru and Mount Elgon as well as the Crater Highlands in Tanzania. The Ol Doinyo Lengai volcano remains active, and is currently the only natrocarbonatite volcano in the world.

useful - new crust is being formed at a divergent plate boundary. unfavorable - previous crust destroyed at a convergent plate boundary. Earthquakes and volcanoes are going to be modern-day at the two sorts of limitations in approximately equivalent quantities. although the main severe earthquakes and maximum explosive volcanoes would be chanced on at unfavorable plate margins, alongside with Washington, Japan, New Zealand, and Indonesia. you surely ought to study the very elementary and straightforward concepts of plate tectonics right here, because it is that this form of unifying theory in geology. i'm extremely particular that extremely artwork with the magic little seek container on top of this internet site provide you with some very stable diagrams on the mechanisms and what those limitations look like.

Hi i'm starting my GCSE and i'm just wondering what plate boundary isMount Nyiragongo on? destructive?conservative?constructive?

More information the volcano for you to read. The plate margin is Destructive.
