Questions and Answers

What is the relationship between latitude and temperature?

  • Higher latitude results in higher temperatures due to more direct sunlight.
  • Latitude does not significantly affect temperature.
  • Lower latitude results in lower temperatures due to higher solar angles.
  • Higher latitude has a lower solar angle, leading to lower temperatures. (correct)

How does altitude affect temperature?

  • Altitude has no notable impact on temperature variations.
  • Every 1000m increase in altitude results in a temperature drop of 6.5 degrees Celsius. (correct)
  • Lower altitudes have cooler temperatures due to higher atmospheric density.
  • Increasing altitude increases temperature due to decreased atmospheric pressure.

What happens to air density as altitude increases?

  • Air density remains constant, affecting temperature minimally.
  • Air density increases, resulting in higher temperatures.
  • Air density fluctuates without a consistent trend in temperature.
  • Air density decreases, leading to lower temperatures at higher altitudes. (correct)

Study Notes

Latitude and Temperature

  • Higher latitude means a lower solar angle, which leads to less intense heating.
  • Solar radiation is spread over a larger area at higher latitudes, causing heat dispersion and lower temperatures.
  • Lower latitude means a higher solar angle, which results in more intense heating.
  • Solar radiation is concentrated in a smaller area at lower latitudes, causing higher temperatures.

Altitude and Temperature

  • Higher altitudes have lower temperatures due to less dense air.
  • Less dense air at higher altitudes means fewer air and dust molecules, which retain less heat.
  • Lower altitudes have higher temperatures due to denser air.
  • Denser air at lower altitudes means more air and dust molecules, which retain more heat as gravity pulls them towards the ground.
  • Temperature decreases by approximately 6.5 degrees Celsius for every 1000-meter increase in altitude.
