A volcano is like a giant, hot lava bottle that can change the ground around it, just like when you pour juice from one cup to another.
Volcanoes are mountains with lava inside them, think of it as melted rock that’s really, really hot. When the pressure builds up too much, the lava comes out in a big plop or whoosh, and that's an eruption!
How Lava Builds New Land
Imagine you're playing with clay. Every time you press your hands into it, you make new shapes. That’s what lava does when it flows out of a volcano, it adds new land to the Earth.
Sometimes, after the lava cools down, it turns hard like rock and stays there forever, creating hills or even islands.
How Eruptions Change Old Land
When a volcano erupts, it can also knock things over, kind of like when you drop your blocks and they scatter everywhere. Big eruptions can make craters, which are like giant holes in the ground, and cover areas with ash, making everything look gray for a while.
So, volcanoes are like Earth’s favorite artists, they paint new land and reshape old ones, one eruption at a time!
Examples
- Ash falls from a volcano, making the surrounding area look like it was painted grey.
- A mountain forms where a volcano once erupted.
