Question

Which events are associated with convergent boundaries? Check all that apply.

formation of island chains
creation of mid-ocean ridges
creation of new mountains
formation of earthquakes
formation of volcanoes

Answer 1

Convergent boundaries: where two plates are colliding.

Subduction zones occur when one or both of the tectonic plates are composed of oceanic crust. The denser plate is subducted underneath the less dense plate. The plate being forced under is eventually melted and destroyed.

i. Where oceanic crust meets ocean crust
Island arcs and oceanic trenches occur when both of the plates are made of oceanic crust. Zones of active seafloor spreading can also occur behind the island arc, known as back-arc basins. These are often associated with submarine volcanoes.

ii. Where oceanic crust meets continental crust
The denser oceanic plate is subducted, often forming a mountain range on the continent. The Andes is an example of this type of collision.

iii. Where continental crust meets continental crust
Both continental crusts are too light to subduct so a continent-continent collision occurs, creating especially large mountain ranges. The most spectacular example of this is the Himalayas

Answer 2

Which events are associated with convergent boundaries? Check all that apply.

formation of island chains

creation of mid-ocean ridges

creation of new mountains

formation of earthquakes

formation of volcanoes

Answer:

creation of mid-ocean ridges

creation of new mountains

formation of earthquakes

Reason for the answer: convergent boundary is a tectonic boundary where two plates are moving toward each other. If the two plates are of equal density, they usually push up against each other to form a mountain chain. If they are of unequal density, one plate usually sinks beneath the other.
