Islands can be made when hot lava from inside Earth comes out and cools down into solid rock, just like how chocolate melts and hardens again when it cools.
Imagine you're playing with playdough, and someone pours hot lava (like molten chocolate) onto a plate. When the lava cools, it turns back into solid rock, that’s how islands are made sometimes!
How Volcanoes Make Islands
When a volcano erupts under the sea, it sends up lava like a giant fountain. This lava floats on water and keeps growing bigger and bigger. Eventually, it can rise above the ocean surface, just like when you put ice cubes in a glass of water and they float until they melt and become liquid again.
A Real-Life Example
Think of the island of Hawaii. It was made by volcanoes that erupted under the sea. Over time, these volcanoes kept adding more and more lava to the top of the ocean, like stacking blocks one on top of another, until it became an island you can walk on!
So next time you see a volcano, imagine it could be making an island just like that!
