Question

the diagram shows how thermal energy is transferred from the ground to the air at different altitudes.
use the diagram to complete the sentences.
air at low altitudes is dense than air at high altitudes. there are also air particles pushing down from above. this means that there are air particles to absorb thermal energy in a given area at low altitudes, and the air is insulated from above. in other words, at low altitudes, thermal energy is absorbed, and thermal energy escapes into space.
this explains why low - altitude locations are usually than high - altitude

Explanation:

1. Low-altitude air has more air molecules packed into a given volume under higher atmospheric pressure, making it more dense than thin high-altitude air.
2. The overlying atmospheric layers mean more air particles press down on low-altitude air.
3. The higher density means there are more air particles available to absorb thermal energy from the ground in a low-altitude area.
4. The dense lower atmosphere acts as a better insulator, trapping heat more effectively than the thin upper atmosphere.
5. More thermal energy is absorbed at low altitudes due to the denser air particles.
6. Less thermal energy escapes to space from low altitudes because of the insulating dense air.
7. This heat trapping leads low-altitude locations to be warmer than high-altitude locations.

Answer:

1. more dense than air at high altitudes
2. more air particles pushing down from above
3. more air particles to absorb thermal energy
4. better insulated from above
5. more thermal energy is absorbed
6. less thermal energy escapes into space
7. warmer than high-altitude locations
