The aleutian islands extend westward from southern alaska to form the northern boundary of the pacific ocean. these volcanic islands were formed by the a. subduction of a continental plate (b. subduction of an oceanic plate)-answer but why is this the answer? c. divergence of a continental plate d. divergence of an oceanic plate

The correct answer is B

Subduction of a ocean plate.

Aleutian islands extend westward from southern Alaska to form the northern boundary of the Pacific Ocean when the Pacific plate gets subducted under North American Plate at a dip of 45 degrees. The pacific  is an oceanic tectonic plate that lies beneath the Pacific Ocean. And thus the correct answer is option B

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.
