The Spratly Islands are in the sea. 
The Spratly Islands are in the South China Sea. 
The islands are made of sand and coral. Many are very small. Some are just reefs under the water. 
Many animals live in the sea here. You can find fish and sea turtles. Sea birds also use the islands to rest.
Some people live on the islands. They work as fishermen. Other people stay there for the military.
It is a busy place for ships. Many boats travel through these waters.
The Spratly Islands sit in the South China Sea. 

Many animals live in these waters. There are hundreds of types of coral. You can find many fish and sea turtles. Some turtles are very rare. Seabirds also use the islands to rest and breed.
Most of the islands have no people living on them. However, some islands have military bases. Many countries claim these islands. These groups include China, Taiwan, and Vietnam. They also include Malaysia and the Philippines. These islands are important for fishing. They may also hold oil and natural gas. Ships use these waters to travel the world.
The Spratly Islands are a large group of islands in the South China Sea. 

Many of these islands are very small and hard to reach. The northeast part of the group is called the Dangerous Ground. This area has many low islands and sunken reefs. These reefs often rise quickly from very deep water. This makes it a hard place for ships to travel safely. 
In 1843, a British whaling captain named Richard Spratly saw Spratly Island. The islands were named after him. For a long time, the islands were mostly just coral islets where seabirds lived. By 1939, they were still mostly just small bits of coral. In 1986, a source from China said the area had 14 islands. It also listed 113 submerged reefs and many other underwater banks. 
There are many different resources found around these islands. They have rich fishing grounds that provide many fish. There may also be large amounts of oil and natural gas under the sea. Some people have even mined guano, which is bird droppings, from the islands.
Nature is very busy in the waters around the Spratly Islands. There are nearly 3,000 different marine species living there. This includes 382 types of hard coral and 524 kinds of fish. Sea turtles, like the green turtle, also use the islands to nest.
The Spratly Islands are a large, disputed archipelago located in the South China Sea. 

Most of the islands in this group are cays. A cay is a small, low-lying island formed on top of old, degraded, or submerged coral reefs. The islands are mostly made of biogenic carbonate. This is material created by living organisms, such as coral. These carbonate accumulations sit upon the high crests of submarine ridges. Geologists call these raised blocks of the Earth's crust horsts. These horsts are part of a complex system of half-grabens and rotated fault-blocks. These geological structures lie parallel to magnetic anomalies in the nearby oceanic crust.
The formation of these islands happened in two distinct tectonic periods. First, tectonic stretching occurred during the Late Cretaceous and Early Oligocene. This happened during the rifting and sea-floor spreading that created the South China Sea. Later, during the Late Oligocene and Early Miocene, additional stretching and faulting occurred. This activity happened within the Spratly Islands and the nearby Dangerous Ground. During this time, corals and other marine life colonized the crests of the horsts. Over time, the remains of these organisms built up to create the modern reefs and cays.
The geography of the region can be quite difficult to navigate. The northeast section is known as the Dangerous Ground. This area is characterized by many low islands and sunken reefs. Some reefs rise abruptly from ocean depths greater than 1,000 meters. 
The history of the islands is tied to exploration and many different claims. The archipelago was named after Richard Spratly, a British whaling captain. He sighted Spratly Island in 1843. In 1939, the area consisted mostly of coral islets inhabited by seabirds. Today, the islands are highly contested by several nations. China, Taiwan, the Philippines, Vietnam, and Malaysia all occupy different islands or reefs with military forces.
There are significant economic resources in and around the Spratly Islands. The area contains rich fishing grounds and may hold large oil and natural gas reserves. Some islands have been used for guano mining, which is the collection of bird droppings used for fertilizer. 
The ecology of the Spratly Sea is incredibly diverse and complex. Scientists have recorded 2,927 different marine species in the area. This includes 382 species of hard coral and 524 species of marine fish. The islands provide vital habitats for seabirds and sea turtles. The green turtle and the hawksbill turtle both use these islands.
