Worked practice questions

Heating of air in contact with the warm ground, layer by layer, is called:

  1. Advection
  2. Radiation
  3. Conduction
  4. Convection
Show answer and solution

Correct answer: C. Conduction

1. Energy flows from warmer to cooler body in contact. 2. This is conduction. 3. It heats the lower layers of the atmosphere. _Source: syllabus Fundamentals of Physical Geography, Chapter 9, Solar Radiation, Heat Balance and Temperature._

Vertical heating of the atmosphere by rising air currents is called:

  1. Conduction
  2. Advection
  3. Insolation
  4. Convection
Show answer and solution

Correct answer: D. Convection

1. Heated air rises in currents. 2. This is convection. 3. It is confined to the troposphere. _Source: syllabus Fundamentals of Physical Geography, Chapter 9, Solar Radiation, Heat Balance and Temperature._

Heat transfer through horizontal movement of air is called:

  1. Advection
  2. Convection
  3. Conduction
  4. Radiation
Show answer and solution

Correct answer: A. Advection

1. Horizontal movement matters more than vertical. 2. It is advection. 3. It causes most diurnal weather change in middle latitudes. _Source: syllabus Fundamentals of Physical Geography, Chapter 9, Solar Radiation, Heat Balance and Temperature._
