Question

quick check question one

in the diagram, the red and blue circulating arrows represent what process?

convection
conduction
radiation
freezing

Explanation:

Identify the process shown in the diagram

The diagram illustrates a cross-section of the Earth's interior, showing circular flow patterns in the mantle layer. The red arrows represent warmer, less dense material rising, while the blue arrows represent cooler, denser material sinking.

Match the circular flow to heat transfer mechanisms

This circular movement of a fluid (or semi-fluid rock in the mantle) driven by differences in temperature and density is the definition of convection. Conduction involves direct contact transfer, radiation involves electromagnetic waves, and freezing is a phase change.

Answer:

• Convection (Correct answer)
• Conduction
• Radiation
• Freezing
