Weather is the condition of air during a brief period. Climate is the average weather of an area over a long period of time. There are four elements that weather is dependent on. A. Temperature is the degree of heat in the atmosphere. Temperature has a great effect on air pressure.
Temperature goes up in the morning because the air becomes warmer after sunrise.
The temperature goes down as the sun sets and the air becomes cooler. Temperature also changes with the seasons. B. Air Pressure is the force of the atmosphere pushing on the earth. Changes in air pressure bring about changes in the weather. Rising air pressure usually brings sunny, settled weather.
