ACTIVITY 1_NSTP2

What is climate?

• A long period of time. 

• Atmospheric conditions of a place at a particular point in time. 

• Average atmospheric conditions of a place over a long period of time, usually 30 years. 

• Current weather outlook of a place. 

What is climate change?

• Don't know

• Change in global climate, such as an increase in the global temperature and major variations in precipitation patterns. 

• The earth has become sick. 

• A change in the earth's climate due to human causes. 

The greenhouse effect is beneficial as it helps to sustain life on earth by naturally trapping heat in the atmosphere. 

• True

• False

The enhanced greenhouse effect is the increase in global temperatures due to an increase in atmospheric greenhouse gases. 

• True

• False

What is another term for enhanced greenhouse effect?

• Global cooling

• Global freezing

• Global barbecue

• Global warming

During volcanic eruptions, large volumes of sulfur dioxide released into the atmosphere can work together with dust and ash to cause global cooling.

• True

• False

How can deforestation NOT lead to an increase in atmospheric carbon dioxide and climate change as a result?

• Setting forest fires to clear forests rapidly for agricultural activities release carbon dioxide due to combustion. 

• The loss of forests as a carbon sink i.e. forests absorb carbon dioxide during photosynthesis.

• The loss of oxygen which makes the earth warmer, as forests contribute oxygen to the atmosphere during photosynthesis. 

• Carbon oxidation whereby carbon in exposed soil (without vegetation cover) reacts with oxygen to produce carbon dioxide. 

Climate change can lead to _______________.

• sea level rise and floods in coastal areas

• droughts

• spread of dengue fever and malaria

• all of the above

Climate change can affect the growing season of crops, which can result in both increase in food supply and food shortages at the same time. 

• True

• False

The burning of fossil fuels (eg. coal, gas, and oil results in the release of  __________.

• Oxygen

• Carbon dioxide

• Methane

• Nitrogen
