B. The simplest explanation of weather is that it is the condition of atmosphere at a definite time and place on the Earth. It can be hot or cold, wet or dry, calm or stormy, clear or cloudy. This condition is influenced by a number of atmospheric factors, such as air pressure, temperature, humidity, precipitation.

C. Temperature is how hot or cold something is, for example the atmosphere or the sea. Temperature is measured ['me33d] in degrees Celsius (centigrade) or Fahrenheit.

F. Atmospheric pressure is the weight1 of air on the Earth's surface. Pressure is shown on a weather map with lines called isobars. Warm air is lighter than cold air, cold air is heavier than warm air. Low pressure near the Earth's surface occurs when air is warm and rises. High pressure occurs when air becomes colder and falls.

G. When the sun shines, the Earth's surface2 is heated. The sun heats the Earth unevenly and influences the atmosphere. Warm and cool air move and change air pressure. The movement of air around the Earth from high pressure to low pressure, of the cold and warm air brings about winds.

H. The sun also heats the water which is on the Earth in rivers, lakes, seas, oceans, and in the upper layer of the ground.

That means that it contains water in the form of vapour. Humidity is the amount of water vapour in the atmosphere. Humidity is measured as a percentage 100% humidity is the point (Tonica) where the air can hold no more water vapour.

D. Precipitation is the term given to moisture that falls from the air to the ground. The most common form of precipitation is rain, snow, hail, sleet, drizzle, fog, mist.

E. The air around us is never completely dry. It is usually moist.
