Slide1Three Types of Heat Transfer Three Types of Heat Transfer 6 th Grade 6 th Grade Convection and the Mantle Convection and the Mantle
Slide2RadiationRadiation The transfer of energy through space is called radiation . The transfer of energy through space is called radiation . Takes place with no direct contact between a heat source and an object. Takes place with no direct contact between a heat source and an object. Sunlight is radiation that warms the Earth’s surface. Sunlight is radiation that warms the Earth’s surface. Other examples: flame or open fire. Other examples: flame or open fire.
Slide3ConductionConduction Heat transfer within a material or between materials that are touching is called conduction . Heat transfer within a material or between materials that are touching is called conduction . Responsible for some of the heat transfer inside Earth. Responsible for some of the heat transfer inside Earth.
Slide4ConductionConduction In conduction, the heated particles of a substance transfer heat through contact with other particles in the substance. Conduction heats the pan and the contents of the pan. In conduction, the heated particles of a substance transfer heat through contact with other particles in the substance. Conduction heats the pan and the contents of the pan.
Slide5ConvectionConvection Heat is also transferred by the movement within fluids – liquids and gases. Heat is also transferred by the movement within fluids – liquids and gases. Convection is heat transfer by the movement of currents within a fluid/ Convection is heat transfer by the movement of currents within a fluid/ Heated particles of fluid begin to flow. The flow transfers heat from one particle of fluid to another. Heated particles of fluid begin to flow. The flow transfers heat from one particle of fluid to another. Heat transfer by convection is caused by the differences of temperature and density within a fluid. Heat transfer by convection is caused by the differences of temperature and density within a fluid.
Slide6DensityDensity Density is a measure of how much mass there is in a volume of a substance. Density is a measure of how much mass there is in a volume of a substance. When a liquid or gas is heated, the particles move faster and spread apart. As a result, the particles of the heated fluid occupy more space. The fluid’s density decreases. When a liquid or gas is heated, the particles move faster and spread apart. As a result, the particles of the heated fluid occupy more space. The fluid’s density decreases. When the fluid cools, the density increases because the particles slow down and move closer together. When the fluid cools, the density increases because the particles slow down and move closer together.

Slide9Convection Currents Convection Currents A convection current is the flow that transfers heat within a fluid/ A convection current is the flow that transfers heat within a fluid/ Heating and cooling of the fluid, changes in the fluid’s density, and the force of gravity combine to set convection currents in motion. Heating and cooling of the fluid, changes in the fluid’s density, and the force of gravity combine to set convection currents in motion. Convection currents continue as long as heat is added. Convection currents continue as long as heat is added.

Slide11Convection Currents in Earth Convection Currents in Earth In Earth’s mantle, large amounts of heat are transferred by convection currents. In Earth’s mantle, large amounts of heat are transferred by convection currents. Heat from the core and the mantle itself causes convection currents in the mantle. Heat from the core and the mantle itself causes convection currents in the mantle.
