Weather changes are due to the sun. The sun provides energy. The sun energy raises the temperature of air on earth. The air heats unevenly. The uneven warming causes air to move. This process causes our weather.

Meteorologists study weather. They study air masses, pressure systems, humidity and temperature to predict weather.

Almost all weather begins because of the sun. The sun provides the energy. The energy raises temperatures on earth. It raises temperatures on earth unevenly. The uneven warming causes the movement of air. Combining sun energy, air movement and the rotating earth gives you a weather machine!

Meteorologists study weather. They observe weather conditions and patterns. Weather forecasts are only an educated guess. By studying air masses, pressure systems, humidity and temperature, meteorologists can predict weather with good results.

Meteorologists observe weather conditions and weather patterns. They use their observation data to make weather predictions are called forecasts. Weather forecasts are only educated guesses. By studying air masses, pressure systems, humidity and temperature, meteorologists can predict or forecast weather with good results.
