Which is an example of convection?
in a mountain forest, the sun heats up the ground.
on a hot day, amaya pours water on her face to cool off.
at the beach, stephan’s feet get hot walking across the sand.
above the sea, warm air rises, cools, and sinks.

Above the sea, warm air rises, cools, and sinks.

Explanation:

There are three modes of heat transfer:

Conduction: This type of heat transfer happens when there is direct contact between the two object.

Convection: This type of heat transfer happens when there is a movement of fluid (liquid or gas).

Radiation: This type of heat transfer happens when there is direct transfer of energy through space.

1. In a mountain forest, the sun heats up the ground: It is an example of Radiation

2. On a hot day, Amaya pours water on her face to cool off: It is an example of conduction

3. At the beach, Stephan’s feet get hot walking across the sand: It is an example of conduction

4. Above the sea, warm air rises, cools, and sinks: It is an example of convection
