Hello Explorers! Captain Nova here with a cool science discovery! 🌋
Did you know that volcanoes erupt because of super-hot melted rock deep inside the Earth?
Far below our feet is a layer called the mantle. In some places, the rock there becomes so hot that it melts into a thick liquid called magma. This magma slowly rises through cracks in the Earth’s crust.
As more magma rises, pressure begins to build. When the pressure becomes strong enough, the magma pushes its way out of the ground — and a volcano erupts!
Once magma reaches the surface, we call it lava. Lava flows down the sides of the volcano and eventually cools into brand-new rock.
Volcanoes may look powerful and dangerous, but they also help create new land and shape our planet over millions of years!
🌎 Captain Nova’s Explorer Question
Can you name three types of volcanoes?
Hint: One of them is called a shield volcano!
Stay curious, explorers.
There is always something amazing to discover on Planet Earth!
