Study Notes
Earth's Spheres
- Earth is made up of four interconnected spheres: biosphere, lithosphere, hydrosphere, and atmosphere.
- The biosphere includes all living organisms, the lithosphere includes the Earth's crust and upper mantle, the hydrosphere includes all water, and the atmosphere includes the air that surrounds Earth.
- The carbon cycle is an example of how materials move through the different spheres.
 Carbon Cycle
- CO2 (carbon dioxide) is the largest source of carbon on Earth.
- Plants absorb CO2 through photosynthesis and release oxygen back into the atmosphere.
- Deforestation reduces the number of plants available to absorb CO2, leading to an increase in atmospheric CO2.
- The Industrial Revolution, with its reliance on fossil fuels, has also contributed to increased atmospheric CO2.
Acid Rain
- Acid rain is caused by the release of pollutants, such as sulfur dioxide and nitrogen oxides, into the atmosphere.
- These gases dissolve in rainwater and fall to the earth as acid rain, which can damage living organisms, pollute water, and erode stone.
Global Systems
- The climate system is a complex interplay of the Earth's atmosphere, biosphere, hydrosphere, and lithosphere.
- Human activity, such as the burning of fossil fuels, has contributed to climate change.
- The Kyoto Protocol is an international treaty that aims to reduce greenhouse gas emissions.
 Climate Change
- There is debate about the structure of strategies to combat climate change.
- The current Federal Government scheme to tackle climate change was subject to political debate.
- There are arguments both for and against an Emissions Trading Scheme, a policy that aims to reduce greenhouse gas emissions.
