How are Igneous Rocks Formed?
- Igneous rocks are formed from melted rock called magma.
- When magma cools down, it becomes solid and turns into igneous rock.
- This process can happen inside the earth or on the surface after a volcano erupts.
Examples:
- Granite is an igneous rock that forms when magma cools slowly underground.
- Basanite forms when lava cools quickly after a volcanic eruption.
- Obsidian is smooth and shiny because it cools so fast that it doesn't have crystals.
Fun Fact: Igneous rocks help us learn about Earth's inside because they come from deep within the planet!
