The areas of Earth where life is present are referred to as the biosphere

The entire amount of water on a planet is known as the hydrosphere

The solid outer layer of Earth is known as the lithosphere also referred to as the rocky shell of the plane

The Earth's atmosphere spans from the surface of the Earth to regions above the Earth as far as 10,000 kilometres

Techniques made by Aboriginal people tohelp preserve the envirionment

Aboriginal people have contributed to looking after Australia by using their extensive knowledge of the land and traditional techniques. These techniques have helped Australia greatly as these techniques have helped to preserve the land and as well to keep the animals healthy for the future generation. A tradition the Aboriginal people used was burning when Aboriginal people would use “cool burning”. Cool burning was when Aboriginal people would set a small blaze to clear underneath. Through this technique, the Aboriginal people can help make a patchy environment for small animals.

TWO international agreements relating to biodiversity with a focus on Australi

An international agreement to cut greenhouse gas emissions was formed through the Kyoto Protocol. The Kyoto Protocol was established because too much greenhouse gases can worsen the risks of global warming. Around the time when the globe began to be threatened by global warming, the Kyoto Protocol was developed in Japan. The protocol's primary goal was to lower glasshouse gas emissions in order to protect the Earth from further damage.

An international pact to safeguard the atmosphere and ozone layer is known as the Montreal protocol. It was claimed that the strategy was effective because it decreased ozone-depleting chemicals like carbon dioxide. Man-made chemicals known as ozone-depleting compounds steadily destroy our ozone layer.

Greenhouse effect

Greenhouse effect

The greenhouse effect occurs when different types of gases are gases known as greenhouse gases trapped in the Earth’s atmosphere. This intern causes the Earth to rise in temperature. But what are some greenhouse gases? Some greenhouse gases are carbon dioxide, methane and nitrous oxide. All these gases are produced into the atmosphere by humans by burning fossil fuels and other methods.

But what does this mean for the ecosystem in Australia? Well since the greenhouse effect traps gases in the atmosphere and intern causes the Earth to get warmer. The temperature of the Earth could greatly affect Australia's rainfall. As well as cause a drought that could seriously affect many people. As having no water farmers are unable to grow crops. Also, farmers that have animals will struggle to keep them alive as this clean water is a necessity for animals to grow and survive.

How do the spheres work together?

These 4 spheres all interact with each other. For example, the hydrosphere produces rain from clouds in the atmosphere to the lithosphere which then produces streams of water. With streams, people are able to drink water as well as have water for plant growth in the biosphere.

Can Australia as a society can continue to contribute to the Greenhouse effect in the long term

Can Australia as a society can continue to contribute to the Greenhouse effect in the long term

Australia is the second biggest coal exporter and the fifth largest coal producer in the world, therefore Australia's society can continue to make a long-term contribution to the greenhouse effect. Australia produces a lot of coal, thus it releases a lot of carbon dioxide into the atmosphere, which causes pollution that can affect the land, air, and water.
