Meteorology
[underlined] TROPOSPHERE [/underlined]
(1) It is the layer in which weather occurs. (2) It varies with latitude, extending to a greater height over the Equator (50,000ft) than over the poles (25000ft).
(3). In the troposphere there is a lapse rate of about 3°F per 1,000ft.
[underlined] Stratosphere [/underlined].
(1). There is no weather.
(2). Temperature remains constant.

Stratosphere contains.
Nitrogen 80%
Oxygen 20%
Carb Dioxide .03%
Water Vapour 1%-4%
Rare Gases

[underlined] The Molecular Theory of Magnetism [/underlined]

All magnetic materials contain what are called molecular magnets, each molecule is in itself a magnet in the ordinary way these molecules are lying in a haphazard manner but when magnetised they arrange them selves in an orderly manner with their North seeking poles all pointing in the same direction, the theory of the rearrangement is supported by the fact that if a magnet is cut, the remaining pieces each have a red and blue pole.
[underlined] The magnetic field [/underlined]

The magnetic field is the area surrounding a magnet throughout

[underlined] Properties of Atmosphere [/underlined]
(1) Has weight
14lb per sq inch.
(2). It is compressible.
& when compressed its temperature rises.
When it expands it gets colder.

[underlined] Humidity [/underlined].
(1) Psychrometer or Wet & Dry Bulb Thermometer.
[underlined] Evaporation [/underlined].

The presence of water vapour [missing words] air is due to evaporation.
[underlined] Saturated Air [/underlined].
Is air holding a maximum amount of water vapour.
[underlined] Actual Amount of water [/underlined] in the air usually measured in grammes per Killometre [sic].
[underlined] Relative Humidity [/underlined] is the ratio of water content of the air to the water vapour it could hold if saturated (at that temperature) expressed as a %

Properties of a Magnet
These properties were first discovered in China, the lodestone being found to have directive properties. There are 5 magnetic materials – lodestone, (which is a natural magnet), ferrous metals, Iron, nickel, cobalt & manganese. These materials, allowed with other metals still retain their magnetic properties but the resulting magnetic force is weakened by the inclusion of non magnetic materials. In a magnet the magnetic poles are roughly one eight of the length of the magnet distance from each end. The distance between them is the effective length (like poles repel & unlike poles attract).
The pole which points north is called the North seeking or red pole & the one which points south the South seeking or blue pole.
Poles in any magnet are of equal
