Volcanic island arcs are associated with .

a)transform plate boundaries

b)divergent plate boundaries

c)ocean-ocean convergent plate boundaries

d)ocean-continent convergent plate boundaries

C)ocean-ocean convergent plate boundaries

Explanation: Ocean-ocean convergent plate boundaries are boundaries formed along Volcanic arcs,this type of arcs happen beneath the Ocean,and are formed on adjacent plates.

Volcanic Island arcs are different from island arcs because Island arcs form continental Tectonic plates boundaries, this type of volcanic eruptions are accompanied by Rings of fire and they surround the Pacific Ocean.

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
