The correct answers are:

- allows fuel to burn;

- is the gas that animals breathe;

- forms ozone that absorbs the Sun's harmful rays;

The oxygen is one of the most important gases in the Earth's atmosphere and it has many roles in it.

This gas is the one that allows the things to burn. If there's no oxygen, that the burning of the things on the Earth would not be possible, including the burning of the fuels.

The oxygen is the gas that enables the life of the animals on the planet. Almost all animals on the Earth use the oxygen to breathe and for their bodily functions, and without it, the animals on our planet will not be able to survive.

The ozone layer is basically a layer in the stratosphere made out of ozone, which is a substance made out of three atoms of oxygen. This layer is very important because it has the property to absorb the harmful rays from the Sun, thus enabling the life on Earth to exist and not be fried to death.

What are some examples of enviromental problems solved by applied geography?​
Sphinxa [80]

Answer:

The three environmental problems are as follows:

Climate Change

Deforestation

Water crisis

These are some of the well-known environmental problems of the world where environmental scientists are working to find the solution.

As far as climate change is concerned, the whole world is co-operating because it is not related to any country or region but related to our mother earth. Scientists are working to reduce the temperature of the earth which is a big concern of this issue and it can be done only by the reduction of the carbon emission which we release from fossil fuels burning. Scientists are working to find an alternative source of energy by which we can bypass the fossil fuels usages and make our earth clean and green.

Deforestation is one of the other concern and it can be checked by the plantation of new trees as well as by reducing our dependency on paper which we get from trees and there are other ways also that country should have to cut their pristine forest to set up industries and housing colonies and all nations have to maintain some percentage of their land as a forest.

The water crisis is also a big concern of this 21st century, It can be resolved by the use of water in a proportionate way and also by saving the groundwater for future generations. Scientists are also working in the new-technologies by which we can desalinate water from the sea.

For all this information on the environmental concern, you need to go through any environmental journal or magazine.
