When two oceanic plates converge, some magma erupts under the ocean, forming volcanoes that may rise above the sea. These volcanoes can form a curved:

A) island arc
B) line of calderas
C) sequence of magma chambers
D) reef

Island Arc

An island arc is a chain of islands formed from the volcanic activity associated with the subduction zones of tectonic plates, typically located in the ocean.

Calderas

Large, basin-like depressions resulting from the collapse of a volcano after a major eruption.

Magma Chambers

Large pools of molten rock located beneath the Earth's surface, where magma accumulates before it is erupted as lava during a volcanic eruption.
