The atmosphere is a *layer of gases

surrounding the Earth. Most planets, and

even some moons, have got an atmosphere,

but it is very different from the Earth´s

atmosphere.

The atmosphere makes the Earth,s climate moderate and protects the planet from the effects of direct sun radiation.

Without the atmosphere the Earth could´nt sustain life.

The atmosphere of our home planet is made up of three primary gases. These gases are oxygen 21%, nitrogen 78%, and argon 0.8 %. In additiion to these three gases thre are many other gases in the atmosphere in small amounts. Additionally there are small particles floating in the atmosphere such as dust, water, and pollen.

The air has no colour, but the dust, water, smoke, pollen and other particles make it possible for us to see it.

The first layer of the atmosphere is made out of the gases that we breath everyday. This layer is called the troposphere. The troposphere is the layer that we live in.

The next layer of our atmosphere is called the stratosphere. Above the stratosphere lies the mesosphere, followed by the thermosphere and finally the exosphere. The mesosphere and thermosphere are often referred to together as the ionosphere because they reflect the ionized energy of the Sun.

Most of the gases in our atmosphere have little to no affect on our weather. However, a few gases have a significant effect on the weather that we experience arounf the world. Carbon dioxide is one of these gases.

Carbon dioxide has the unique characteristic of absorbing infrared radiation, or the heat sent to the Earth by the Sun. This helps to keep the lower atmosphere warm enough for life to exist.When you breath out, your body releases small amounts of carbon dioxide.

Over the last hundred years humans have been artificially adding a significantly higher amount of carbon dioxide into the atmosphere. This has mainly been through the burning of fossil fuels. What will happen if carbon dioxide levels become too high?

Many scientists belive that there is a possibility

that the Earth´s temperature will rise causing many

unpredictable effects known as “greenhouse effect”

The amount of water vapor found in the air remains constant on average, however, it can vary greatly from one place to another. Some parts of the Earth have high humidity levels, while other have very dry air. What effect does this water vapor have on the atmosphere?

Much of what we consider weather is caused by water vapor.

The clouds in the sky are largely made up of it, and it is the

condensation of this vapor into droplets that creates rain

and snow.

Meteorologists are people who work on weather prediction.

This prediction is usually called “weatherforecast”.

Weather prediction is often represented in a weather map.

26by DONOS

People use different tools to predict weather; some of them are very familiar, like the thermometer (it measures temperature), the anemometer (it measures the speed of wind), the weathercock (measures the direction of the wind) or the barometer (it measures air pressure)

At present metheorologists working on weather stations get information with more complex tools, like weather satellites and doppler radars.
