Factors Affecting Temperature

Question 1

Will warm ocean currents increase or decrease temperatures in costal areas and explain your answer.

Answer 1

They will increase the temperature in costal areas and this is caused by the fact that the winds blowing from a warm ocean current will be warm and this will bring warmer temperatures along with it.

Question 2

True or False (if false explain your answer).

The Benguela current brings warmth to the east coast.

Answer 2

False, The Algulhas current brings warmth to the south coast

							OR False, The Benguela current brings cool temperature to the west coast.

							OR False, The Mozambique current brings warmth to the east coast.

Question 3

How does aspect affect temperature in the Northern Hemisphere?

Answer 3

In the northern hemisphere South facing slopes are warmer than North facing slopes because on a South facing slope the suns rays will shine directly onto a south facing slope where on a north facing slope the suns ray shine obliquely.

Question 4

Explain how altitude affect temperature.

Answer 4

At a higher altitude there will be lower temperatures as there is thinner air and there are fewer particles particles to retain the suns heat therefore the air will be colder and it is colder because of insolation being heat from the suns rays.

Question 5

Define insolation.

Answer 5

Insolation is solar radiation which is heat that comes from the sun’s rays.

Question 6

Define terrestrial radiation.

Answer 6

Terrestrial radiation is the heat that is given to land and is then re-radiated to warm the air.

Question 7

What is latitude?

Answer 7

Latitude is how far away a place is in relation to the equator.

Question 8

Which region is colder(polar/equatorial) and explain your answer.

Answer 8

Polar regions are colder because the sun’s rays strike at an oblique angle, have to travel further, have to heat a larger area and have to pass through more atmosphere hence they are colder.

Question 9

Fill in the gaps:

At the equator the sun’s rays strike __________ , pass through _____ atmosphere hence it is ____________.

Answer 9

Directly, less, hotter

Question 10

How does continentality affect temperature? (8 Marks)

Answer 10

In inland areas land is heated extremely(1), land is heated in thin surface(1) and land loses it’s heat quickly(1). That is why inland areas experience extreme temperatures(1).
In oceanic areas water is heater moderately(1), Is heated deeply(1) and retains it’s heat.(1) That is why Oceanic areas experience moderate temperatures(1).
