Heat is transferred around and through Earth in three different ways: conduction, convection and radiation. Carefully examine the image below, which type of heat transfer is being shown by Letter "B"?

Answer 1

Without the ability to see the image you are referring to, I can provide a general explanation of the three types of heat transfer:

1. Conduction: This is the transfer of heat through a solid material. It occurs when molecules in a hot part of an object vibrate and pass on their energy to adjacent cooler molecules. An example would be a metal spoon left in a hot pot of soup.

2. Convection: This is the transfer of heat by the movement of fluids (liquids or gases). In convection, warmer areas of a liquid or gas rise to cooler areas, and cooler areas sink. This cycle creates a convection current. An example would be boiling water, where hot water rises to the top and cooler water sinks.

3. Radiation: This is the transfer of heat through electromagnetic waves, which can occur through a vacuum (like space). An example is the heat from the sun warming the Earth.

If you describe the image or the context of Letter "B," I can help you identify the type of heat transfer represented.
