Give a reason for each of the following:

(i) The waters of the Oyashio Current form the richest fishing grounds in the world.

(ii) There is heavy rainfall in Queensland but the Atacama desert is arid.

(iii) Rich fishing grounds are located on the Pacific coast of North America.

(i) The waters of the Oyashio Current form the richest fishing grounds in the world owing to the extremely high nutrient content of the cold water and the very high tides in some areas, which further enhances the availability of nutrients.

(ii) Warm currents flow towards Queensland which make the air warm and enable it to acquire greater moisture. Thus, the winds increase the amount of precipitation in Queensland while Atacama desert owe their existence to some extent to Benguela and Peru currents which are cold and keep the air dry and devoid of moisture.

(iii) Rich fishing grounds are located on the Pacific coast of North America due to the convergence of warm and cold currents.
