Heat Transfer Earth Science

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

Radiation is a method of thermal energy transfer. It refers to the transfer of heat energy that moves what way?

• Through empty space

• when objects touch

• Only through solids

• In the motion of fluids

Which of the following is an example of heat transfer through radiation in Earth's Systems?

• Heat rising through vents in the ocean floor

• Warm air replacing cooler air

• Beach sand getting warmed by the sun

• Hot gases given off during a volcanic eruption

Emily is drawing a diagram of heat transfer. She begins with radiation. Next to the word radiation she will describe how radiation transfers heat. Which of the following would be the best description for Emily to write here?

• When fluids move

• Through empty space

• Only through solids

• When objects touch

Mr. Parker's class has created a list of different ways heat transfer happens in Earth's systems. The list is shown above. Which is an example of heat transfer through radiation?

• Example 1

• Example 2

• Example 3

• Example 4

Michael and Isabella are working together on an assignment. They must find an example of heat transfer by convection from some illustrations. Which illustration will best represent convection?

• An illustration of heat being transferred by wind

• An illustration of heat being transferred by objects in contact

• An illustration of heat being transferred between rocks

• An illustration of the sun's heat moving through empty space

Anthony and Madison are making a poster to show how heat can be transferred by conduction. Which of the following is the best example of conduction for their poster?

• The heat of the sun warming a lake

• Warm and cold water flowing in a bathtub

• A steak being heated when it touches a hot pan

• Warm air rising and cold air sinking on a prairie

Joshua has an assignment for school. He must find an example of conduction. He must look for a situation where what is true?

• Solid materials

• Liquids and gasses

• Objects in contact

Which of the following is an example of heat transfer by conduction?

• Warm and cold water circulating in the ocean

• Sunlight warming a room early in the morning

• Hot air rising and cold air sinking on a beach
