| Question | Answer |
| The atmosphere. Composition and structure | The atmosphere is the gaseous layer that surrounds the Earth. |
| Gaseous state | Fixed mass, variable volume and variable shape. |
| Composition of the atmosphere | |
| Structure of the atmosphere | |
| The importance of atmosphere for living things | - The regulatory action of the Earth's temperature retains the heat from the Sun. - The protective action stop external agents. |
| Atmospheric gases and life | - Carbon dioxide (CO2) is essential for autotrophic oranisms to perform photosynthesis. - Oxygen (O2) is essential for the respiration of living things. Nitrogen (N) is essential for the construction of proteins. Water vapour (H2 O) forms part of the water cycle. |
| Atmospheric phenomena produced by water vapour | Humidity refers to the quantity of water vapour found in the air at any given time. |
| Atmospheric phenomena due to condensation | Condensation nuclei - Clouds -Fog -Dew -Frost |
| Atmospheric phenomena due to precipitation | Precipitation is the fall of water from the atmosphere to the ground, in a liquid or solid state. Rain, snowflakes and hail. |
| Air pollution | Air pollution is the alteration of the normal composition of air. |
| Types of pollutants | - Natural - Artifitial *Physical #Electromagnetic radiation #Noise #Radioactivity *Chemical |
| Consequences of air pollution | - Global level: acid rain. -Ecosystems: destroy natural habitats. -Individual level: respiratory problems and other disorders. |
| Preventative and corrective measures | - Clean and purify. - Reduce emissions. - Encourage reforestation. - Reduce energy consumption. - Substitute traditional sources of energy. - Reduce the amount of residues of rubbish , and reuse and recycle. |
| The Greenhouse effect | The greenhouse effect is the phenomena by which the atmosphera retains some of the heat from the Sun. |
| Causes of the increase in the greenhouse effect | - The burning of fossil fuels. - The destruction of forests. |
| Consequences of the increase in the greenhouse effect | Global warming. Climate change. |
| The ozone layer | - X-rays and gamma rays. - Ultraviolet rays. - UVA rays. - UVB rays. - UVC rays. |
| Causes of the depletion of the ozone layer | Hole in the ozone layer. CFCs or chlorofluorocarbon gases. |
| Consequences of destroying the ozone layer | - Effects on the skin. - Effects on the body defences. - Effects on sight. |
