WARMING THE EARTH AND THE
ATMOSPHERE
Reporter: Glendel J. Caroz
Does the sun move?
Yes or No?
Temperature and Heat Transfer
*Temperature refers to the degree of hotness
or coldness of an object or a substance,
typically measured using a scale such as
Celsius (°C) or Fahrenheit (°F).
Temperature
The energy associated with this motion is
called kinetic energy, the energy of
motion. The temperature of the air (or any
substance) is a measure of its average
kinetic energy.
Simply stated, temperature is a measure of
the average speed (average motion) of the
atoms and molecules, where higher
temperatures correspond to faster average
speeds.
If we warm the air inside, the molecules would move faster,
but they also would move slightly farther apart— the air
becomes less dense, as illustrated in the picture above.
Conversely, if we cool the air back to its original temperature,
the molecules would slow down, crowd closer together, and
the air would become more dense.
HEAT TRANSFER
Heat
is energy in the process of being
transferred from one object to another
because of the temperature diff erence
between them.
In the atmosphere, heat is transferred
by conduction, convection, and
radiation.
CONDUCTION
• Conduction is the transfer of heat energy through a substance
or between substances that are in direct contact with each
other.
• In conduction, heat energy is transferred from higher
temperature regions to lower temperature regions within the
material.
• This transfer occurs due to the collision of particles within the
material, where faster-moving particles collide with slower-
moving particles, transferring kinetic energy.
Conduction Example
CONVECTION
• Convection is the transfer of heat energy through the movement
of fluids (liquids or gases) caused by density differences within the
fluid.
• It involves the transfer of heat energy from one place to another
by the actual movement of the heated fluid.
• Convection occurs in fluids because heated fluids become less
dense and rise, while cooler fluids become denser and sink,
creating circulation patterns known as convection currents.
RADIATION
• Radiation is the transfer of heat energy through electromagnetic
waves, such as infrared radiation, without the need for a
medium to carry the heat.
• Radiation does not require direct contact between objects and
can travel through space, allowing the Sun's energy to reach the
Earth.
BALANCING ACT—ABSORPTION,
EMISSION, AND EQUILIBRIUM
ABSORPTION
• Definition: Absorption refers to the process of a
substance absorbing energy, typically from
electromagnetic radiation such as light.
• Mechanism: Atoms, molecules, or materials absorb
specific wavelengths of light, causing their electrons to
transition to higher energy states.
EMISSION
• Definition: Emission refers to the release of energy, often
in the form of electromagnetic radiation, by a substance.
• Mechanism: Excited atoms, molecules, or materials return
to lower energy states, emitting photons of specific
wavelengths.
EQUILIBRIUM
• Definition: Equilibrium occurs when the rates of
absorption and emission of energy by a substance
are balanced, resulting in no net change in energy.
• Mechanism: At equilibrium, the number of absorbed
photons equals the number of emitted photons,
maintaining a steady state.
