The Atmosphere
The Earth is surrounded by a mixture of gases we call the atmosphere. The air we breathe is part of the atmosphere. The atmosphere is composed of a series of layers. The most important layer is the troposphere. The troposphere is in contact with the Earth's surface. The atmosphere is fundamental to the existence of life. Unfortunately, human activity is polluting the atmosphere.

3.1. What is air pollution? For life to exist, it is essential that the composition of air remains stable. When we pollute the air, we are changing its composition. When we add or remove any component, we can produce negative effects. 3.2. [...]
-
4.1. Environmental effects of pollution The effects of pollution are harmful. The most important effects are the depletion of the ozone layer, the greenhouse effect and acid rain. [...]

5.1. Weather and climate Weather refers to the atmospheric conditions (temperature, humidity, atmospheric pressure, wind and cloud cover) in a particular place at a particular time. [...]
-
6.1. Wind Wind is the movement of air produced by the differences in air pressure between two different places. These differences occur because the heating of the Earth's surface is uneven. [...]
-
Anticyclones and cyclones The atmospheric pressure is not the same at all points on the Earth's surface. Weather maps show, amongst other things, the atmospheric pressure. [...]
