Heat - 3

When we come out in the sun, we feel warm. How does the heat from the sun reach us? what is the first statement of the audio clip?

• Atmospheric heating the earth and its atmosphere is warmed by the energy from the Sun

• In this video, you will find out what happens to solar energy as it enters the atmosphere

• Three things work together to transfer energy to our atmosphere: radiation conduction and convection

• Radiation is the transfer of energy as electromagnetic waves.

• Although the Sun radiates a huge amount of energy, the earth only receives a tiny fraction of this energy

When we come out in the sun, we feel warm. How does the heat from the sun reach us? what is the second statement of the audio clip?

• But, this small fraction of energy is enough to drive the weather cycle and sustain life on earth thermal

When we come out in the sun, we feel warm. How does the heat from the sun reach us? what is the third statement of the audio clip?

• But, this small fraction of energy is enough to drive the weather cycle and sustain life on earth thermal

• Conduction is the transfer of thermal energy through a material

• Three things work together to transfer energy to our atmosphere: radiation conduction and convection

• Radiation is the transfer of energy as electromagnetic waves.

• Although the Sun radiates a huge amount of energy, the earth only receives a tiny fraction of this energy

When we come out in the sun, we feel warm. How does the heat from the sun reach us? what is the fourth statement of the audio clip?

• But, this small fraction of energy is enough to drive the weather cycle and sustain life on earth thermal

• Conduction is the transfer of thermal energy through a material

• Thermal energy is always transformed; transferred from warm to cold areas.

• Radiation is the transfer of energy as electromagnetic waves.

• Although the Sun radiates a huge amount of energy, the earth only receives a tiny fraction of this energy

When we come out in the sun, we feel warm. How does the heat from the sun reach us? what is the fifth statement of the audio clip?

• But, this small fraction of energy is enough to drive the weather cycle and sustain life on earth thermal

• Conduction is the transfer of thermal energy through a material

• Thermal energy is always transformed; transferred from warm to cold areas.

• When air molecules come in direct contact with the warm surface of the earth, thermal energy is transferred to the atmosphere

• Although the Sun radiates a huge amount of energy, the earth only receives a tiny fraction of this energy

When we come out in the sun, we feel warm. How does the heat from the sun reach us? what is the Sixth statement of the audio clip?

• But, this small fraction of energy is enough to drive the weather cycle and sustain life on earth thermal

• Conduction is the transfer of thermal energy through a material

• Thermal energy is always transformed; transferred from warm to cold areas.

• When air molecules come in direct contact with the warm surface of the earth, thermal energy is transferred to the atmosphere

• Convection is the transfer of thermal energy by circulation or movement of a liquid or gas

When we come out in the sun, we feel warm. How does the heat from the sun reach us? what is the Seventh statement of the audio clip?

• Most thermal energy in the atmosphere is transferred by convection

• Conduction is the transfer of thermal energy through a material

• Thermal energy is always transformed; transferred from warm to cold areas.

• When air molecules come in direct contact with the warm surface of the earth, thermal energy is transferred to the atmosphere

• Convection is the transfer of thermal energy by circulation or movement of a liquid or gas

When we come out in the sun, we feel warm. How does the heat from the sun reach us? what is the Eighth statement of the audio clip?

• Most thermal energy in the atmosphere is transferred by convection

• For example as air is heated it becomes less dense and Rises

• Thermal energy is always transformed; transferred from warm to cold areas.

• When air molecules come in direct contact with the warm surface of the earth, thermal energy is transferred to the atmosphere

• Convection is the transfer of thermal energy by circulation or movement of a liquid or gas

When we come out in the sun, we feel warm. How does the heat from the sun reach us? what is the Ninth statement of the audio clip?

• Most thermal energy in the atmosphere is transferred by convection

• For example as air is heated it becomes less dense and Rises

• Cool air is denser so it sinks as is cool air sinks; it pushes the warm air up.

• When air molecules come in direct contact with the warm surface of the earth, thermal energy is transferred to the atmosphere

• Convection is the transfer of thermal energy by circulation or movement of a liquid or gas

When we come out in the sun, we feel warm. How does the heat from the sun reach us? what is the Tenth statement of the audio clip?

• Most thermal energy in the atmosphere is transferred by convection

• For example as air is heated it becomes less dense and Rises

• Cool air is denser so it sinks as is cool air sinks; it pushes the warm air up.

• The cool air is eventually heated by the Earth's surface and begins to rise again in this cycle of warm air rising and cooling causes a circular movement of air called a convection current

• Convection is the transfer of thermal energy by circulation or movement of a liquid or gas
