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.
