Focus:
1) How does the Sun’s energy create weather?
2) How is the Sun’s energy transferred to create weather?
3) What is the structure of Earth’s atmosphere?
Key Terms:• radiation• conduction• convection• thermometer

Energy in the Atmosphere
• The Sun’s energy drives the weather.
1) The Sun heats Earth’s surface
2) Earth’s surface transfers that energy to the atmosphere.
3) Differences in heat transfer drive the weather.

Transferring Energy
• Energy is transferred in three different ways.
1) Radiation
2) Conduction
3) Convection

Transferring Energy
• Radiation - the transfer of energy through space.
Example: The Sun heating Earth’s surface.(Step 1)

Transferring Energy• Conduction - the transfer
of energy through direct contact.
– Heat always moves from warmer areas to cooler areas
Example: Earth’s surface heating the atmosphere.(Step 2)

Transferring Energy• Convection - the transfer of
energy through a liquid or gas caused by differences in density.
– As heat increases (), density decreases ().
Example: Movement of heat through theatmosphere to create differences
inheat.(Step 3)

Measuring Energy• Heat - the total movement (kinetic energy)
within a substance.
• Temperature - the average movement (kinetic energy) within a substance.- Measured by a thermometer- Units: degrees Celsius (ºC)
Q: Why does the mercury in a thermometer rise as temperature increases?

The Atmosphere• Earth’s atmosphere
has four layers.1) Troposphere 2) Stratosphere3) Mesosphere4) Thermosphere
• Layers are identified by changes in temperature.

Troposphere• The layer closest to Earth’s surface.
– Height : 0 - 12 km• Temperature decreases () with
increasing altitude.• Air pressure decreases () with
increasing altitude.• Atmospheric layer where weather occurs.
