2 Weather and Climate atmosphere.
➢ Meteorology – The study of weather and climate. Cloud Types – Clouds comes in many shapes, size and heights.
➢ Weather – The day to day condition of the atmosphere. It includes
temperature, precipitation, pressure and wind.
➢ Climate – The average weather conditions of a place taken over a
period of years.
➢ Factors that affect the weather.
Temperature – A measure of how warm or cold it is. Cloud Cover – The amount of the sky covered by clouds

are usually cooler. Water areas (Lakes/ Seas) have a cooling effect
and produce light winds. Hilltops are usually cool and windy.
