All about temperature

Air temperature is determined by the earth’s heat emitted which is absorbed by greenhouse gases which in turns heats up the atmosphere. Earth’s heat is called....

• Infrared Radiation

• Shortwave Radiation

• Ultraviolet Radiation

What is the diurnal temperature range shown in the diagram?

____degrees celcius

The Six’s thermometer is placed in a box called the _________ Screen

Which is NOT a feature of the Stevenson Screen and its best location?

• At least 1.5m above the ground

• Black in colour to reflect the incoming shortwave radiation

• It has louvred windows to allow for air circulation

• Located on grassy surface which is a poor conductor of heat

Why do the Equatorial regions experience warmer temperature than the polar regions?

Which of the statement IS NOT applicable as a reason?

• As the sun rays hit the earth surface at a high angle of incidence

• As the sun's rays are concentrated over a small area

• As the sun rays hit the earth surface at a low angle of incidence

Which city has the smallest annual temperature range?

• San Francisco

• Minneapolis

• Wichita

• Dallas

Why does San Francisco has the smallest annual temperature range?

• because it experiences the continental effect and hence has warm summers and cool winters

• because it experiences the maritime effect and hence cool summer and warm winter

• because it experiences the continental effect and hence has cool summers and warm winters

• because it experiences the maritime effect and hence warm summer and cool winter

Locations at higher altitude experience lower temperature as it is further away from the ____________ radiation emitted from the earth surface. Furthermore, the air is also _____________, thus has lesser ability to absorb heat.

• shortwave, denser

• infrared, denser

• shortwave, less dense

• infrared, less dense

Temperature decreases 6.5 deg cel with every increase of 1,000 metres. If the mean annual temperature of Georgetown is 28 deg cel, calculate the likely mean annual temperature at the peak of Mount Kinabalu.

Desert areas are very hot in the day and very cold in the night as these areas lack cloud cover. Thus, _______ amounts of energy reaches the earth surface heating it up during the day, while ________ amount of heat radiated from earth’s surface escape into space during the night.

• high, high

• high, low

• low, high

• low, low
