Magmatic processes are how rocks inside Earth change and move when they’re hot and melted.
Imagine you have a big pot of soup on the stove, it’s bubbling and moving around. Now think about that pot as being deep inside the Earth, where really hot rock melts into something like lava. That melted rock is called magma.
Like Soup in a Pot
Just like how soup can bubble up and spill over the edge of the pot, magma can rise through cracks in Earth's layers. Sometimes it cools down slowly underground, making big, smooth rocks, kind of like how soup thickens when it cools. Other times, it comes out really fast, like when you pour hot soup into a bowl, that’s like lava flowing out of a volcano.
Making New Rocks
When magma cools, it hardens and becomes rock. If it cools slowly, the rock has big crystals, think of it like making candy that gets time to grow big sugar crystals. If it cools quickly, the rock is small and glassy, like when you make candy and let it cool fast.
So, magmatic processes are all about how melted rock moves, changes, and becomes new rocks inside Earth, just like your soup changing from hot liquid to a solid bowl of food!
Examples
- Magma is like hot, melted rock that can create new landforms when it cools down.
- When magma hardens, it becomes igneous rocks such as granite or basalt.
