Carbon + Water Cycle
Carbon And Water Cycle
| Question | Answer |
|---|---|
| What contains carbon | all living things contain carbon your body is made up of 20% carbon by mass your body is constantly "burning" compounds of carbon to keep you alive in a process called respiration you exhale carbon dioxide |
| How is Carbon Dioxide added to the atmosphere | Respiration Burning of fossil fuels Natural processes e.g. volcanoes, forest fires and decay of dead animals and plants |
| How is carbon dioxide removed from the atmosphere | Plants via photosynthesis Rain -when rain falls through the atmosphere it reacts with carbon dioxide to form carbonic acid Lakes and seas |
| How is carbon Stored underground | Limestone (calcium carbonate) Oil and Gas Coal Turf |
| What is a problem with the carbon cycle today | we are adding too much carbon dioxide into the atmosphere, this is causing an increase in overall temperature due to it trapping the Earth's heat. This leads to rising sea levels, unpredictable weather and climate change |
| Irish efforts to reduce Global Warming | Carbon Tax Subsiding production of green energy |
| What processes add water to the atmosphere | Evaporation from seas, Lakes and land using the sun as a source of energy Transpiration from trees and plants to help them cool down Combustion |
| What is evaporation | Evaporation is the change of state of a liquid to a gas at the surface of a liquid |
| What is Transpiration | Transpiration is the release of water from the leaves of trees and plants |
| How does Combustion produce water | Water vapour is produced as a by-product of burning gas, petrol or oil |
| What happens to the water vapour as it enters the atmosphere | as the water vapour rises, it cools and condenses The water vapour is converted to a cloud Some clouds may be blown by wind over land as it moves over land it may be blown higher over mountains and cool further |
| What happens to the cloud | Clouds Cool Further the cloud can no longer hold onto the water droplets and the water falls as rain, hail, sleet or snow This is known as precipitation |
| What happens to the water when it reaches land | Most water makes it back to the sea eventually -water collects in streams, lakes and rivers (runoff) |
| What happens to the water back at sea | We can harness some of the sea water returning to sea -Hydroelectricity dams can trap the water and convert it's potential energy into electrical energy in a generator Some water is also routed to homes and industry for consumption |
