Does it have to be hot to make a tornado?

No, tornadoes form when warm, moist air collides with cool, dry air. Temperature differences at various levels of the atmosphere, not the temperature on the ground, contribute to the creation of tornadoes.


What is true A warm air is less dense than cool air B warm air is as dense as cool air. C warm air has no density. D warm air is denser than cool air?

A warm air is less dense than cool air (Option A). When air is heated, the air molecules become more energetic and spread out, decreasing its density. Conversely, cool air has denser molecules as they move slower and are more tightly packed together.


What is the name of the process that causes droplets to form on the outside of the glass?

Condensation is the process that causes droplets to form on the outside of a glass. This occurs when warm air comes into contact with a cold surface, causing the air to cool and release moisture in the form of droplets.


What do updrafts and downdrafts form?

Updrafts form when warm air rises due to lower density, often in association with convection. Downdrafts form when cool air sinks due to higher density, typically associated with thunderstorms or cold air masses. Both are critical components of atmospheric circulation and can influence weather patterns.


How does convection cell forms and causes wind?

Convection cells form in the atmosphere when warm air rises and cool air sinks, creating a cycle of air movement. This air movement results in the formation of winds as the air moves from areas of high pressure (where cool air sinks) to areas of low pressure (where warm air rises). The rotation of the Earth also contributes to the creation of global wind patterns.
