10 Questions
Carbon dioxide released in the atmosphere creates a green house effect by trapping the heat radiated from the ______
earth
It is therefore called a greenhouse gas and without it the earth would have been too cold to ______ in.
live
However, when its level in the atmosphere increases due to factory smoke or car ______, the heat retained increases the temperature of the earth.
fumes
This is called global ______.
warming
This rise in temperature causes the snow in coldest parts of the world to ______.
melt
Match the following consequences of increased carbon dioxide in the atmosphere with their effects:
Rise in temperature = Melting of snow in coldest parts of the world Increase in greenhouse gases = Global warming Rising sea levels = Floods in coastal areas Drastic climate changes = Extinction of some plants and animals
Match the following terms with their descriptions:
Greenhouse gas = Traps heat radiated from the earth Global warming = Temperature increase due to higher levels of greenhouse gases Sea level rise = Result of melting snow in coldest parts of the world Climate change = May lead to extinction of some plants and animals
Match the following causes with their effects:
Factory smoke and car fumes = Increase in carbon dioxide levels in the atmosphere Melting snow in coldest parts of the world = Rising sea levels Higher temperature of the earth = Global warming Extinction of plants and animals = Drastic climate changes
Match the following terms with their impacts on the environment:
Greenhouse effect = Retains heat radiated from the earth Rising sea levels = Floods in coastal areas Drastic climate changes = Potential extinction of plant and animal species Melting snow in coldest parts of the world = Contributes to sea level rise
Match the following outcomes with their causes:
Temperature increase on earth = Higher levels of greenhouse gases Floods in coastal areas = Rising sea levels Extinction of plants and animals = Drastic climate changes Melting snow in coldest parts of the world = Increased carbon dioxide in the atmosphere
Explore how carbon dioxide acts as a greenhouse gas, trapping heat and leading to global warming. Learn about the impact of rising temperatures on snow melt and sea levels.
