What is the smallest island in the world?

In the Micronesian archipelago in the Pacific Ocean, there is a beautiful coral island, with an area of only 22 square kilometers, it is the rich country of Nauru, and it is also the smallest island nation in the world. The whole island is slightly oval in shape, surrounded by coral reefs, and the coast is a silvery white sandy beach, from which the ground gradually rises inward, and there is a circle of crops nearly 300 meters wide, and then there are coral cliffs 12 to 60 meters high. It is inferred from the horizontal lines of the cliffs that the formation of Nauru Island has a history of at least 10,000 years, and above the cliffs is the plateau that accounts for 85% of the entire island's area, that is, the main body of Nauru.

Nauru is only 53 kilometers from the equator, so it has a hot climate and a lot of rain throughout the year. Nauru has a population of about 8,000 people, mainly in villages around the island. Despite its small population, this island nation is one of the richest countries in the world.

Its main source of wealth is the abundant phosphate mines on the island, and in the central plateau, almost all covered with this high-quality natural phosphate fertilizer, up to 6 10 meters thick, with a total reserve of about 100 million tons, it is formed by mineralization of guano accumulated for a long time. 60% of the country's employed population is engaged in phosphate mining, the annual output remains above 2 million tons, the huge income ensures the rapid development of social welfare, the country implements tax exemption, free housing, electricity, medical care, etc., every 3 people have a car, but the country needs to import from food to fresh water.

The answer to the brain teaser is: a safety island! The answer to the realistic point is:

01 Nauru Island.

Nauru Island is a beautiful coral island, known as "Paradise Island", the whole island is oval-shaped, currently covering an area of square kilometers, is the smallest island in the world, and is also the seat of the Republic of Nauru, the smallest island country in the world. Due to its geographical location, the land area of Nauru Island is still shrinking under the impact of the sea. There is also a sharp turn in the brain and the answer is a safety island.

Nauru is home to the Republic of Nauru, the smallest island nation in the world, located in the Micronesian archipelago in the west-central South Pacific Ocean, with an area of 24 square kilometres, which has slowly declined to square kilometres in recent years.

Nauru Island is a beautiful coral island, known as "Paradise Island", the whole island is oval in shape, surrounded by coral reefs, all of which leak out only at low tide. Located just 53 kilometers from the equator, Nauru has a tropical rainforest climate with hot and rainy weather throughout the year. Nauru's economy is about to fall due to over-exploitation, where about 40% of marine life is killed by silt and phosphate runoff, and phosphate reserves are almost completely depleted.

Due to its geographical location, the land area of Nauru Island has gradually shrunk under the impact of the sea, and the land area of the island has decreased from 24 square kilometers to 21 square kilometers in the past few decades, and at this rate, Nauru is on the verge of becoming one of the most likely countries in the world to sink to the bottom of the sea, and may disappear from the sea in a few years.

If the question is a sharp brain turn, then the answer is a safety island on the road.

Safety Island refers to the relatively stable land mass that exists in the tectonic activity area or between the active tectonic zone, and takes it as the main object of selecting the engineering construction base. The degree of stability is determined by the tectonic position, shape, medium properties, structural characteristics, development history (especially the evolution history of the geological period) and the present tectonic stress field. Signs of relative stability are:

The tectonic type is a block of land, or a folded belt that has been ossified; The medium structure is a relatively uniform continuum, and the rock is a monolithic structure or a block-like and thick-layered structure, and the weak interlayer and weak structural plane are not developed. It is not a strongly tectonically active zone, and there are no large-scale active faults passing through; At present, the tectonic stress field is a low stress value area; There is no seismic fault, there is enough distance from the historical strong earthquake area, there is little microseismic activity, the ** effect is not significant, and it belongs to the low intensity area; There is no modern volcanic activity, and hydrothermal activity is not strong; Landslides, collapses, debris flows, etc. are not strong, or are limited to certain local areas; Non-destructive man-made engineering geological processes, such as land subsidence and subsidence caused by the pumping or exploitation of gas, liquid and solid minerals in large quantities, induced by deep water injection or reservoir impoundment**, etc. The quantitative evaluation of the safety island must carry out basic work such as active structure, geological and intensity assessment, and effectively carry out the determination of various stability indicators of the plot such as modern in-situ stress and large topographic changes. According to the structural part where the safety island is located, it can be divided into mid-zone plots, inter-zone plots and belt edge plots. According to the genesis, it is divided into basement blocks, caprock blocks, magmatic rock blocks and metamorphic rock blocks.

This concept is of guiding significance in engineering construction. [1]

The smallest island nation in the world is Nauru, located in the western part of the South Pacific Ocean in the Western Islands of Micronesia, known as the "Paradise Island". This island nation in the Pacific Ocean, located 60 kilometers south of the equator, has an area of only 24 square kilometers and a population of 10,000 people (2006 statistics). Among them, 58 are Nauruan, 26 are South Pacific islanders, and the immigrants are mainly Europeans and Chinese.

The Nauruans are a branch of the Micronesians, a mixture of Marais, Melanesians, and Polynesians, with English as the lingua franca.

Hummingbird (wood nymph) is a collective name for about 600 species of hummingbirds in the order Swifts, and is the smallest known bird in the world. The hummingbird is small and able to hover in the air by flapping its wings quickly, about 15 to 80 times per second, depending on the size of the hummingbird. Hummingbirds get their name from the humming sound of flapping their wings.

Hummingbirds are the only birds that can fly backwards. Hummingbirds can also hover in the air as well as fly left and right. Of all the animals, hummingbirds are the most beautiful and colorful.

The little hummingbird is a masterpiece of nature: light, swift, agile, elegant, gorgeous feathers, this little darling has it all.

The smallest hummingbird (mellisuga helenae or calypte helenae) is found in Cuba and the island of Pines, slightly longer than centimeters (inches) and weighs about 2 grams. It is the smallest living bird and is the smallest warm-blooded vertebrate along with the little shrew.

The smallest island is the island of safety The smallest island country is the country of NauruIn the Pacific Ocean, there is a beautiful coral island in the Micronesian archipelago, with an area of only 22 square kilometers, it is the rich country of Nauru, and it is also the smallest island country in the world.
