Comparison of chemistry and physics. Chemistry and physics are branches of science that both study the behavior of matter. The difference between the two lies in their scope and approach. Chemistry focuses on describing matter by its intrinsic behavior within itself as an entity, or the systems that compose matter.
Understanding basic thunderstorm formation and structure can help you make safe decisions. Thunderstorms are formed by a process called convection, defined as the transport of heat energy. Because the atmosphere is heated unevenly, an imbalance can occur which thunderstorms attempt to correct. Three things are needed for convection to be a significant hazard to flight safety: moisture, lift and instability. MoistureâSufficient moisture must be present for clouds to form.
Thunderstorms. Because tornadoes often accompany thunderstorms, pay close attention to changing weather conditions when there is a severe thunderstorm watch or warning. A severe thunderstorm watch means severe thunderstorms are possible in your area.A severe thunderstorm warning means severe thunderstorms are occurring in your area.now how to distinguish between the siren's warnings for a tornado watch and a tornado warning. A tornado watch is issued when weather conditions favor the formation of tornadoes, for example, during a severe thunderstorm.
