Islands are like big pieces of land surrounded by water! 🌊 Some islands are made when volcanoes explode and the lava cools down to make land. Others are made when the water gets lower and shows land that was hidden before. 🏝️
Some islands are so small that only a few animals live there, like turtles or birds! 🐢🐦
Islands form in different ways! 🌋 Some are created by volcanoes under the ocean. When lava cools and piles up over time, it forms an island—like Hawaii! 🌊
Other islands are parts of continents that broke off long ago. Some even form when coral reefs grow big enough to reach the surface! 🐠
Fun fact: Greenland is the world's biggest island, but most of it is covered in ice! ❄️
Islands form through several geological processes. 🌋 Volcanic islands, like Hawaii, are created when underwater volcanoes erupt and lava builds up over thousands of years. Continental islands, like Great Britain, were once connected to continents but separated due to rising sea levels or tectonic shifts.
Coral atolls form when coral reefs grow around submerged volcanoes, creating ring-shaped islands. Some islands, like the Maldives, are barely above sea level! 🌊
Fun fact: The island of Surtsey (Iceland) appeared in 1963 after an underwater eruption—scientists watched it form in real time! 🔥
