Here's a breakdown:
* Convection is a heat transfer process that occurs in fluids (liquids and gases).
* Hotter fluid is less dense and rises.
* Cooler fluid is denser and sinks.
* This continuous cycle of rising and sinking creates a circular current.
Examples of convection:
* Boiling water: Hot water at the bottom rises, while cooler water at the top sinks, creating a circular flow.
* Weather patterns: Warm air rises, cools, and then sinks, creating wind patterns.
* Earth's mantle: The Earth's mantle is heated by the core, causing hot rock to rise and cooler rock to sink, driving plate tectonics.
