Ocean trenches are the deepest parts of the ocean floor. They are shown as blue lines on the map below. The area where frequent volcanic activity takes place around the Pacific Ocean is known as the Ring of Fire. This area is highlighted on the map.

What does the map show about the locations of the trenches and volcanoes?
A.
Trenches and volcanoes occur around the same locations.
B.
Trenches and volcanoes occur in the Northern Hemisphere only.
C.
Trenches occur only in the Southern Hemisphere, and volcanoes occur in the Northern Hemisphere.
D.
Trenches occur only in oceans, but volcanoes never occur in oceans.

Answer 1

The correct answer is A. Trenches and volcanoes occur around the same locations.

The map indicates that ocean trenches, which are the deepest parts of the ocean, are found in areas that correspond closely with the locations of volcanic activity, particularly within the Ring of Fire in the Pacific Ocean.
