Hey there future physicist! Ever wondered why we have those huge continents and how they got where they are today? Well, you're about to discover one of Earth's coolest secrets - Convection Currents. 🌊🌋

• Convection: A method of heat transfer where fluids (like molten rock) move around because of temperature differences. Hotter fluid rises, cooler fluid sinks.
• Earth's Core: It's like the planet's hot, fiery furnace. With temperatures soaring, it's responsible for those awesome convection effects we're about to learn.
• Upper Mantle: Just below Earth's surface, it's where all the convection magic happens!

• New Crust Creation
  • Where? Bottom of the Atlantic Ocean (among other places).
  • How? Due to convection effects beneath Earth's surface.
    • Real-World Example: Think of it like a lava lamp. The blobs rising up? That's similar to the molten rock rising from the Earth's upper mantle!
• Two Convection Currents
  • They move in the same direction.
  • Material rises (or upwells) at the top of these currents and reaches Earth's surface at ocean depths.
    • Real-World Effect: Because of this, the Americas, Europe, and Africa are slowly moving apart. Imagine continents playing a game of "slow-motion tag" - they're moving at a few centimeters a year!
• Subduction
  • Opposite of upwelling! Here, convection currents pull material back down below the surface.
    • Real-World Example: Think of a conveyor belt in a sushi restaurant. Some plates (or crust) come up, and some go down, just like the movement of Earth's crust!
• Result of Convection
  • Continental Drift! Over time, these currents reshaped our continents.
    • Real-World Impact: The unique shapes of our continents, like Africa's horn or South America's tail, are thanks to these epic convection currents!
