[A] Insolation
[B] Radiation
[C] Conduction
[D] Convection
Show Answer
Correct Answer: C [Conduction]
Notes:
Conduction is the heat transfer through matter by molecular activity. The air in contact with the land gets heated slowly and the upper layers in contact with the lower layers also get heated. This process is called conduction. Conduction takes place when two bodies of unequal temperature are in contact with one another; there is a flow of energy from the warmer to cooler body.
24. What is the force that results when there is a difference in pressure across a surface?
[A] Frictional force
[B] Coriolis Force
[C] Pressure Gradient force
[D] Gravitational force
Show Answer
Correct Answer: C [Pressure Gradient force]
Notes:
Pressure Gradient is the change in the rate and direction of pressure. Close spacing of isobars indicates a steep or strong pressure gradient whereas wide spacing indicates weak gradient.
25. Which instrument is used to measure the wind direction?
[A] Barometer
[B] Thermometer
[C] Weather vane
[D] Hygrometer
Show Answer
Correct Answer: C [Weather vane ]
Notes:
Wind is an air movement having both direction and speed. The direction of the wind is measured by a conventional instrument called weather vane or the wind vane
