Final answer:
The three spheres of Earth in which energy is transferred by convection are the atmosphere, the hydrosphere, and the mantle.
Step-by-step explanation:
The three spheres of Earth in which energy is transferred by convection are the atmosphere, the hydrosphere, and the mantle.
In the atmosphere, convection occurs when warm air rises and cooler air sinks. This process influences weather patterns and the movement of air masses.
In the hydrosphere, convection takes place in oceans and other bodies of water. Warm water near the surface rises, while cooler water sinks, creating ocean currents.
In the mantle, convection occurs due to heat transfer from the Earth's core. This movement of molten rock drives plate tectonics and the formation of volcanic activity.
