Geology 2A: Convection and the Mantle

Earth's molten outer core is nearly as hot as ​ (a)  

• the surface of the sun!
• the inside of an apple pie!
• a pot of boiling water!
• a sleeping bag in winter!
• a pop tart fresh out of the toaster!
• a steaming baked potato!
• a roaring campfire!

Match the following types of HEAT TRANSFER to their definitions!

• Heat transfer between objects touching!

• CONDUCTION

• Heat transfer by movement of fluids!

• RADIATION

• Heat transfer with no direct contact!

• CONVECTION

​ (a)   is the transfer of energy that takes place with no direct ​ (b)   between a heat source and an object. Sunlight is an example, because it travels through space to warm the ​ (c)   surface. Another example would be the ​ (d)   you feel while sitting around a ​ (e)   with friends!

• Radiation
• Convection
• Conduction
• contact
• Earth's
• inner

​ (a)   is the transfer of energy that takes place between materials that are touching. A spoon in a pot of soup will heat up while it sits in hot liquid. The particles at the ​ (b)   of the spoon ​ (c)   faster as they heat up and they bump into other particles as they travel ​ (d)   the entire spoon! This type of heat transfer occurs inside our ​ (e)   constantly!

• Radiation
• Convection
• Conduction
• bottom
• vibrate
• up
• planet
• top
• down
• brains

​ (a)   is the transfer of energy that takes place by the movement of fluids. Both ​ (b)   and gases are considered fluids. Heated particles will begin to flow and transfer heat from one part of the fluid to another. As objects heat up, their particles move ​ (c)   and they become less dense. If they ​ (d)   down, their particles will do the opposite and move ​ (e)   !

• Radiation
• Convection
• Conduction
• liquids
• apart
• cool
• together
• fall
• slowly
• minerals

Why does soup rise as it is cooked and

then sink back down to the bottom of the pot?

• The soup cools as it rises, becomes more dense, and sinks!

• The soup heats as it rises, becomes more dense, and sinks!

• The soup cools as it rises, becomes less dense, and sinks!

• The soup heats as it rises, becomes less dense, and sinks!
