4. Atmosphere
4.1. Different layers of atmosphere
4.1.1. The Troposphere
4.1.1.1. This is the lowest part of the atmosphere - the part we live in. It contains most of our weather - clouds, rain, snow.
4.1.2. The Stratosphere
4.1.2.1. contains much of the ozone in the atmosphere.
4.1.3. The Mesosphere
4.1.3.1. third layer of the atmosphere, directly above the stratosphere and directly below the thermosphere. In the mesosphere, temperature decreases as altitude increases.
4.1.4. The Thermosphere
4.1.4.1. region in which temperatures again increase with height. This temperature increase is caused by the absorption of energetic ultraviolet and X-Ray radiation from the sun.
4.1.5. The ionosphere
4.1.5.1. reflects and absorbs radio waves, allowing us to receive shortwave radio broadcasts in New Zealand from other parts of the world.
4.1.6. The Exosphere
4.1.6.1. mainly oxygen and hydrogen atoms
4.1.7. The Magnetosphere
4.1.7.1. region of space surrounding an astronomical object in which charged particles are affected by that object's magnetic field
