Convection Cells: Gizmos Convection Cells Answer Key
Convection cells are circular patterns of fluid motion that occur when a fluid is heated or cooled. The heated fluid rises, while the cooled fluid sinks, creating a continuous cycle of motion.
The formation of convection cells is driven by differences in temperature and density. When a fluid is heated, its density decreases, causing it to rise. Conversely, when a fluid is cooled, its density increases, causing it to sink. This difference in density creates a buoyancy force that drives the fluid motion.
Examples of Convection Cells in Nature, Gizmos convection cells answer key
- Atmosphere: The atmosphere is heated by the sun, causing warm air to rise and cool air to sink. This creates convection cells that drive the wind.
- Oceans: The oceans are heated by the sun, causing warm water to rise and cool water to sink. This creates convection cells that drive ocean currents.
- Mantle: The mantle is heated by the Earth’s core, causing hot rock to rise and cool rock to sink. This creates convection cells that drive plate tectonics.
