Chapter 5 - Temperature

Inversion is where (P.63):

• temperature decrease with an increase in height

• temperature increases with an increase in height

• temperature stays constant with an increase in height

• temperature rises then falls quickly with a decrease in height

An isothermal layer is a layer of air where (P.62):

• an increase in height results in an increase in temperature

• an increase in height results in a decrease in temperature

• density stays constant with height

• temperature stays constant with height

Which of the following statements is correct regarding temperature (P.61)?

• As air is lifted it will be heated by the adiabatic process and the water vapour in the air will condense out as visible droplets forming cloud.

• Air lying in contact with the earth's surface by day will be cooled by conduction.

• The earth does not radiate any heat.

• Heated air will reduce in density and therefore rise.

Which of the following statements is correct regarding surface temperature (P.64)?

• The higher latitude is usually hotter due to a greater heat/unit area

• The Equatorial region is usually hotter due to a greater heat/unit area

• The poles are usually cooler due to a greater heat/unit area

• The temperatures between the poles and the Equator do not vary too much

During the day (P.65):

• cloud cover will increase the maximum temperature

• cloud cover will decrease the maximum temperature

• cloud cover will not affect the surface temperature

• some of the solar radiation is absorbed by the cloud base

The minimum temperature decreases at night due to (P.66):

• mixing of warm and cold air

• solar radiation is reflected back by cloud tops

• cloudy skies

• clear skies with no clouds

Which of the following materials generates the largest diurnal variation (P.68)?

• Sea

• Rocks

• Lakes

• Trees

Which of the following statements is correct regarding temperature in a valley (P.69)?

• Warm air tends to rise from the valley towards the hill above at night, causing the temperature to rise

• Cold air tends to rise from the valley towards the hills, increasing the temperature

• Cold air tends to sink from the hills above at night, lowering the temperature

• Temperature in a valley is the same as the hilltops

On 21st of June, which of the following latitude will be cooler (P.64)?

• 40^o N

• Equator

• 40^o S

• 15^o N

Maximum daytime temperature usually occurs at (P.64):

• 1200hrs

• 1500hrs

• 0800hrs

• 2100hrs
