Which of the following options best describes how heat travels through Earth's layers?

A. Conduction
B. Convection
C. Radiation
D. All of the above

Answer :

Final answer:

Heat travels through Earth's layers in three ways: conduction, convection, and radiation. Conduction occurs when heat is transferred between objects in contact, convection occurs with the movement of mass, and radiation is heat transfer through electromagnetic waves.

Explanation:

The heat travels through the Earth's layers primarily through three modes: conduction, convection, and radiation.

  • Conduction is the transfer of heat between two objects in direct contact with each other, such as when you touch a hot stone on the ground.
  • Convection is heat transfer by the movement of mass. This occurs within the Earth's mantle where hot material rises, cools as it loses heat, and then falls back down to be reheated. It's a cyclical process.
  • Lastly, radiation is heat transfer by electromagnetic waves. The Earth's core, being the hottest layer, radiates heat towards the cooler layers.

In the case of the Earth, all these three methods work together to transfer heat from the hotter core to the cooler crust.

Answer:

Heat flow is high where crust is being created. (Ocean spreading centers are where new crust is being created, and have the highest heat flow.)
