Question

Examine the five words and/or phrases and determine the relationship among the majority of words/phrases. Choose the one option that does not fit the pattern.
A. hydrothermal vents
B. island arc
C. mountains
D. oceanic trench
E. volcanoes

Answer 1

Answer:

D. oceanic trench

Explanation:

A. hydrothermal vents

These are found near volcanic active places. It is a fissure on the seafloor from where geothermally rises.

B. island arc

An island arc is a curved chain of volcanic islands located at a tectonic plate margin, typically with a deep ocean trench on the convex side.

C. mountains

A mountain is a large land-form that rises above the surrounding ground in a limited area. Mountains are formed by tectonic forces or volcanoes.

D. oceanic trench

These are formed by subduction. Although most island arcs might be with an oceanic trench, it is simply a topographic depression of the sea floor, usually narrow in width and very long. An example is the Mariana Trench. An oceanic trench compared to other options on this list does not fit the pattern at all.

E. volcanoes

Volcanoes are caused by a rupture in earth's crust. During volcanoes, hot lava, volcanic ash, and gases escape from a magma chamber below the surface.
