the sun and moon cycle takes up 24 hours, so that is why a whole day is considered 24 hours. there are 7 days in a week based on the earths rotation and position on its axis. there are 12 months in a year because of the lunar cycles, there are just a little bit over 12 in a year. we also have been following this stuff since the time of the ancient babylons and maybe even before.
<h2>Answer: Atoll</h2>
An atoll is an oceanic coral island, usually in the shape of a circular ring, which may be completely or partially closed. It is also called by this term to the set of several small islands that are part of a coral reef, with an interior lagoon that generally communicates with the sea.
Atolls are formed when a coral reef grows around an oceanic volcanic island, as the island sinks into the ocean and disappears underwater, the growth of the coral increases until reaching the sea level, where the action of the wind and the waves erode it and transform it into sand.
It should be noted that this process can take millions of years.
In this sense, the Maldives, an island country located in the Indian Ocean (southwest of Sri Lanka and a few kilometers from India), has these characteristics.
Its territory is organized in 26 atolls and as a country it is constituted by some 1200 islands.

starting billions of years ago Algae converted carbon dioxide to oxygen the algae change the atmosphere of the earth.
A layer (or layers) of gases that surround a planet and are kept in place by the gravity of the planetary body is known as an atmosphere.
It is sometimes referred to as a "sphere," "vapor," or "steam." When the atmosphere's temperature is low and its gravity is strong, a planet can maintain its atmosphere.
The outer part of a star, including the layers above the opaque photosphere, is known as the stellar atmosphere; low-temperature stars may have outer atmospheres with complex molecules.
A whirling disc of gases that compressed against itself and split into a number of evenly spaced rings of gas and matter gave rise to the planets' first atmospheres, which eventually condensed to create the Solar System's planets.
