global warming

Question 1

GREENHOUSE:

Answer 1

Is a glass house that people use for growing plants

Question 2

The air in a greenhouse remains warm because it

Answer 2

traps heat thus can grow crops even during cold
season

Question 3

A greenhouse is used for growing

Answer 3

plants in cooler climates.

Question 4

A greenhouse allows the

Answer 4

short-wave
radiation to escape, but traps the long-wave radiation.

Question 5

greenhouse gases absorb

Answer 5

terrestrial radiation, such as carbon dioxide, methane, CFCs and nitrous oxide

Question 6

impact of Greenhouses on people

Answer 6

1. loss of fertile agricultural land
2. increased costs to protect cities
3. the amount of arable land will be reduced

Question 7

impact of Greenhouses on the environment

Answer 7

1. low-lying areas become lagoons or a new coastline
2. increase in beach erosion
3. melting glaciers

Question 8

how to reduce Greenhouse gases

Answer 8

1. introduce measures to save electricity
2. expand public transport
3. reduce agricultural use of nitrogen fertilizers

Question 9

evidence for global warming?

Answer 9

1. Human activities like manufacturing, transport, and deforestation, add to increasing
   quantities of greenhouse gases to the atmosphere.

Question 10

What are the possible impacts of climate and climate change in Africa?

Answer 10

1. A possible temperature increase of 4°C by 2080.
2. Change of weather patterns causing failure of crops.
3. Flooding and conflicts over scarce resources.

Question 11

Factors that affect the temperature of
different Places around the World

Answer 11

Latitude & altitude

Question 12

how does latitude affect the temp

Answer 12

Temperatures are high in the areas along the equator and low on the poles

Question 13

The distance also traveled by the sun’s rays to get to the equator is

Answer 13

shorter than the distance the rays travel to get to the poles

Question 14

Influence of the Seasons

Answer 14

1. he sun is directly over the Tropic of Capricorn on 21 December hence the
   temperatures are high south of the equator
2. The sun is directly over the Tropic of Cancer on 21 June hence the temperatures are
   high north of the equator

Question 15

the HEAT EQUATOR

Answer 15

The zone of highest temperatures

Question 16

altitude

Answer 16

height above sea level

Question 17

how does altitude affect the temp

Answer 17

Water vapour and carbon dioxide absorb long-wave radiation from the earth

Question 18

Environmental lapse rate(ELR)

Answer 18

The decrease of temperature with height

Question 19

The positive lapse rate of the troposphere is

Answer 19

0.65 / 100m

Question 20

a negative lapse rate.

Answer 20

Temperature inversion.

Question 21

Temperature inversion.

Answer 21

the temperature increases with altitude

Question 22

so the air above a warm surface/ocean is

Answer 22

warm

Question 23

so the air above a cold surface/ocean is

Answer 23

cold

Question 24

Prevailing winds

Answer 24

winds that most often blow this warm or cold air onto the land
and cause temperatures on land to increase or decrease.

Question 25

West coasts are generally cold due to

Answer 25

the cold ocean currents that blow over them

Question 26

east coasts are warm due to

Answer 26

east coasts are warm due to

Question 27

Annual temperature range:

Answer 27

the difference between the highest monthly average
temperature and the lowest monthly temperature of the year.

Question 28

Areas close to the sea have a small

Answer 28

annual temperature range

Question 29

areas far from the
sea will have

Answer 29

larger annual temperature range

Question 30

Oceans moderates the

Answer 30

temperatures of an area

Question 31

Oceans also moderates day and night temperatures causing

Answer 31

smaller diurnal (daily)ranges

Question 32

Maritime climate

Answer 32

morderate temperature
Warm days and cold nights
Small diurnal temperature range
Warm summers and cool winters
Small seasonal temperature range

Question 33

Continental climate

Answer 33

Extreme temperature
Hot days and cold nights
Large diurnal temperature range
Hot summers and cold winters
Large seasonal temperature range

Question 34

Large air masses take time to

Answer 34

heat up and also retain the heat for longer periods of time

Question 35

a large land mass heats up

Answer 35

quickly and losses the heat quickly too

Question 36

Aspect:

Answer 36

the direction in which the slope is facing

Question 37

Southern Hemisphere:

Answer 37

all slopes facing north receives more sun’s rays than the south
facing slopes

Question 38

Northern Hemisphere:

Answer 38

all slopes facing south receives more sun’s rays than the north
facing slopes

Question 39

Global warming

Answer 39

Refers to the increase in average temperatures on earth

Question 40

Causes of global warming:

Answer 40

1. The greenhouse gasses in the atmosphere ( carbon dioxide, carbon monoxide, nitrous oxide, CFCs, methane and water vapor

Question 41

Greenhouse gases are increasing due to:

Answer 41

1. Industrialization and burning of fossil fuels
2. Deforestation (less trees to absorb)
3. Increasing population ( larger intake and release of CO2)
4. Waste dumps

Question 41

Greenhouse gases are increasing due to:

Answer 41

1. Industrialization and burning of fossil fuels
2. Deforestation (less trees to absorb)
3. Increasing population ( larger intake and release of CO2)
4. Waste dumps

Question 42

Evidence of global warming

Answer 42

1. The earth’s temperature is 0.6 - 0.7 warmer than it was 100 years ago
2. High temperatures are causing melting of the icecaps and glaciers to retreat
