Answer 1

1. Plants or animals that can be found in only one place are endemic to this region. This means that they are native or prevalent in this area. For example, the Komodo dragon is a lizard found only in some Indonesian islands.
2. A sea invertebrate that helps to create coral is a polyp. They usually have a long, hollow body ending with a round mouth surrounded by little tentacles. Sea anemones are a type of polyp.
3. An island formed from coral is an atoll. They consist of a reef creating a circle around a lagoon. One of the most famous ones is the Bikini atoll in the Pacific Ocean.
4. A group or chain of islands is an archipelago. Some cities are countries are made out of several scattered islands, like Stockholm (Sweden) or Japan.
5. People groups that are native to a region are indigenous to this region. For example, the Māori people are the indigenous Polynesian population of New Zealand.
6. An area where two pieces of the earth's crust rub against each other shows tectonic activity. In geology, tectonics is the study of the crust of a planet and how it behaves (movement, breaks, etc.).
