What are lava flows?

Lava flows are like rivers of molten rock coming out of a volcano and moving across the ground.

Imagine you're at the beach on a hot summer day, and you pour a big bucket of really hot soup onto the sand. The soup spreads out, flowing and cooling down as it goes. That's kind of what lava does, but much bigger and hotter!

Lava is like super-heated rock that has melted inside the Earth. When a volcano erupts, this molten rock comes rushing out. It can flow slowly or quickly, depending on how runny it is.

If you've ever seen syrup pour from a bottle, you know how slow and thick it can be. Lava that's thick and sticky moves like syrup, it flows slowly and makes wide, flat areas as it cools down.

But if the lava is runny, like water or juice, it moves faster and can travel farther before cooling into solid rock. This kind of lava can even make long, winding paths across the ground, just like rivers!

So next time you see a volcano, imagine it's like a giant soup kitchen, pouring out hot lava that flows all over the place!
