Maldivian soil is formed primarily from the accumulation and decomposition of marine organisms, such as coral, algae, and mollusks, rather than from the weathering and erosion of rocks and minerals. The Maldives are a group of atolls, which are ring-shaped coral reefs that form on top of volcanic seamounts. As these seamounts slowly subside over time, the coral reefs continue to grow upwards, forming islands. The islands of the Maldives are made up of coral sand and other organic material that comes from the coral reefs and the surrounding marine environment. The soil is also influenced by the presence of saltwater and the harsh tropical climate, which affects soil quality and composition.
