B. Kuroshio Current
Explanation
The Kuroshio Current is a warm current that flows in the Pacific Ocean. It originates from the Philippine Sea and flows along the eastern coast of Taiwan and Japan, eventually merging with the North Pacific Current. The Kuroshio Current is known for its warm waters and strong currents, which have a significant impact on the climate and marine life in the region. It is an important current for the transportation of heat, nutrients, and marine organisms across the Pacific Ocean.
6.
The biggest island in the Pacific Ocean is
Correct Answer
C. New Guinea
Explanation
New Guinea is the correct answer because it is the largest island in the Pacific Ocean, covering an area of approximately 785,753 square kilometers. Tahiti, Pacific Ocean, and Oshima Island are not as large as New Guinea and therefore not the correct answer.
7.
Ring of Fire falls in the Pacific Ocean.
Correct Answer
A. True
Explanation
The Ring of Fire is a major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur. It is a direct result of plate tectonics and the movement and collisions of lithospheric plates. This region is known for its high seismic activity and is home to over 75% of the world's active volcanoes. Therefore, it is correct to say that the Ring of Fire falls in the Pacific Ocean.
8.
The smallest island nation in the Pacific Ocean is
Correct Answer
B. Nauru
Explanation

10.
Peruvian Current flows in
Correct Answer
D. Southeast Pacific ocean
Explanation
The Peruvian Current flows in the Southeast Pacific Ocean. This current is a cold oceanic current that originates near the coast of Peru and flows southwards along the coast of Chile. It is driven by the trade winds and the upwelling of cold, nutrient-rich waters from the deep ocean. The Peruvian Current plays a crucial role in the region's climate and marine ecosystem, as it brings cold water and nutrients that support the growth of phytoplankton, which in turn sustains a rich food chain and supports the abundant marine life in the area.
