Heat Transfer on Earth

The sun heats the surface of the ocean's water by radiation. The water heats up and becomes warm. The water then heats up the air by which thermal energy transfer?

• Convection

• Radiation

• Conduction

• Evaporation

What causes the circulation of air in the atmosphere?

• Air in the atmosphere is heated by the sun and sinks to the ground by convection

• The ground is heated by the sun by radiation and then the ground heats the air by conduction, causing the air to rise. The cool air at the top then sinks, creating a convection current.

• Air loses heat to the ground and then rises upward to obtain more energy creating a convection current

• The sun heats the clouds which forces the cooler air to move away and sink by convection

In this experiment, the WARM red dye and the COLD blue dye was placed in the water at the same time. The warm red dye rose to the top while the cold blue dye sank to the bottom.

Conduction can only occur between two objects under the following conditions:

• One object is less dense than the other

• Both objects are in physical contact with each other

• One of the objects is made of metal

• Both objects are exactly the same temperature

Hot coffee is stirred with a spoon; the spoon gets hot due to

• conduction

• convection

• radiation

A student touches her finger to a metal sink and notices her finger is left feeling cold. Which of the following statements correctly explains this observation?

• Heat flows from the students finger to the sink by the process of conduction

• Cold flows from the students finger to the sink by the process of conduction

• heat flows from the students finger to the sink by the process of radiation

• Heat flows from the students finger to the sink by the process of convection
