Atmospheric processes: Practice Questions

What is the geographical term for the rate at which the temperature of the surrounding stationary air decreases with an increase in altitude at a specific time and place?

In the context of the global energy budget, which factor is most likely to cause a significant variation in the insolation received at different locations on the Earth's surface?

The Earth's global radiation budget shows a net surplus of energy near the equator (roughly between 30°N and 30°S) and a net deficit near the poles. Which of the following statements best explains the primary compensating mechanism that prevents continuous warming near the equator and continuous cooling near the poles?

The process by which liquid water changes into water vapour and rises into the atmosphere is known as:

Refer to the bar chart showing the reflectivity of different Earth surfaces. Which surface type is most likely represented by Surface P?

Define insolation as it relates to Earth's atmospheric processes.

Explain how adiabatic warming within the descending limb of the Hadley Cell leads to a decrease in relative humidity, and account for how this process contributes to the formation of the sub-tropical high-pressure belts at approximately \(30^\circ\) latitude.

Analyse how the processes of evaporation and condensation, involving the transfer of latent heat, are fundamental to the formation of clouds and subsequent precipitation, influencing the distribution of different climate zones.

a) Identify and explain two astronomical factors that influence the amount of solar insolation received at the Earth's surface.

b) Describe how the angle of incidence of solar rays affects the intensity of insolation and the global temperature distribution.

With reference to the global atmospheric circulation, explain the formation of two major pressure belts and their associated planetary wind systems.
