白い砂を生み出し地形をつくる
サンゴ礁に棲むサンゴ、魚類、海藻（石灰藻）類、貝類、ウニ類など、様々な生きものの骨格や殻が、長い年月をかけて波などのはたらきにより砕かれ白い砂になります。また、それらの生きものの遺骸が積み重なることで石灰岩となり「サンゴ礁」と呼ばれる地形が形成されます。

白沙與珊瑚礁的形成背景
海浪的運動會磨碎珊瑚、魚類、貝類、海膽和海藻（珊瑚藻）等各種生物的骨骼和外殼，日積月累下轉化為白色的沙粒。這些殘骸不斷累積，還會變為石灰岩，形成一種地形特徵，即珊瑚礁。

흰모래가 생겨나는 지형을 만든다
산호초에 서식하는 산호, 어류, 해조(석회말)류, 조개류, 성게류 등 다양한 생물들의 골격이나 껍데기가 오랜 세월에 걸쳐 파도 등의 작용에 의해 부서져 흰모래가 됩니다. 또한 이 생물들의 유해가 겹쳐 쌓임으로써 석회암이 되어 ‘산호초’라고 불리는 지형이 형성됩니다.

The Natural Processes Behind White Sand and Coral Reefs
With the passage of time, the movement of the waves grinds down the skeletons and shells of various living things—corals, fish, shellfish, sea urchins, and seaweed (coralline algae)— and transforms them into white sand. As the carcasses accumulate, they also turn into limestone, resulting in the formation of a topographic feature known as a coral reef.
