How to protect teeth in daily life

The Pacific Ocean is to the east of China. Because China is located in the east of Asia and the west bank of the Pacific Ocean, the Pacific Ocean is in the east of China.

The Pacific Ocean is the largest and deepest ocean with the most marginal seas and islands in the world. It is located between Asia, Oceania, Antarctica and North and South America.

The Pacific Ocean is divided into eastern, western and central regions:

1. Eastern Area:

The Cordillera Mountains in the Americas starts from Alaska in the north and reaches Tierra del Fuego in the south. In addition to the island groups on the northernmost and southernmost fjord coasts and the Gulf of California deep into the mainland, the coast is straight and the continental shelf is narrow. The main trench is the Acapulco trench in the north and the Peru Chile trench in the south.

2. West:

Part of Asia has a complex structure with tortuous coast. There are prominent peninsulas on the eastern edge of the continent and a series of island arcs off the coast, forming numerous marginal seas. From north to south, there are Bering Sea, Okhotsk Sea, Sea of Japan, Yellow Sea, East China Sea and South China Sea. There are a series of trenches on the outer edge of the island group, including Kamchatka Trench, Thousand Island Trench and Japan Trench in the north, Dongjia Trench and Kermadec Trench in the south, etc.

3. Central region:

The central Pacific Ocean is a vast sea basin, the most stable area of crustal structure, and the depth of seawater is generally about 4570 meters. To the east of 150 ° west longitude is the East Pacific Basin. To the south of the line from the Central American Isthmus through the Cocos Ridge to the Galapagos Islands is the Peru Chile Basin and the Southeast Pacific Basin. The Pacific Antarctica basin is the one that crosses the Southeast Pacific Rise southward. The area between this basin and 150 ° west longitude is the Pacific Antarctica Ridge. 150 ° to 180 ° west longitude, from east to west, there are the Pacific Central Basin, the Mariana Basin and the Philippines Basin; Between New Zealand and East Australia is the Tasman Basin, and to the south is the Macquarie Ridge, the underwater boundary between the Pacific Ocean and the Indian Ocean.
