Section 2.2 - Thermal Energy Transfer In The Atmosphere

Question 1

Thermal energy transfers in 3 ways:

Answer 1

Radiation, conduction, convection

Question 2

______:

• the emission of energy as particles or ______
• this energy, when absorbed by an object, will increase the kinetic energy and therefore temperature of the particles that make up the object

Answer 2

Radiation

Waves

Question 3

______:

• every atom is physically bonded to its neighbours
• if heat energy is supplied to one part of a solid, the atoms vibrate faster
• as they vibrate more, the bonds between atoms are shaken more
• this passes vibrations on to the next atom, and so on
• heat transferred through direct ______ of atoms

Answer 3

Conduction

Collision

Question 4

______:

• the transfer of thermal energy through the ______ of particles from one ______ to another
• as the particles absorb ______, they move apart, decreasing the density
• the lower density air/water will move up, and the higher density air/water will fall down

Answer 4

Convection
Movement
Location
Energy
