The thunderstorms that produce tornadoes often form along cold fronts, when a old air mass pushes into a warm air mass. The cold front develops when a low pressure system (which rotates counterclockwise in the northern hemisphere) pulls cold air from the north. For U.S. storm systems this cold air is pulled down from Canada.
The warm, moist air involved in tornado formation usually comes from a warm body of water. For the United States it is usually the Gulf of Mexico.
Warm anc cold air colliding are not a direct cause of tornadoes, but they can be a step in the process. where they come from depends on the region the weater system is in. But normally the warm air comes from a warm part of the ocean while the cold air comes from a cold region. In the Central United States, for example, the warm air comes from the Gulf of Mexico while the cold air comes from Canada.
Air does go up in a tornado and it is cooler than surrounding air due to decompression. However, it is generally fed by warm air. If too much cold air gets into the circulation, the tornado will dissipate.
When cold air and hot air mix together it forms a tornado.
tornado Thermals, caused by hot ground heating the air close above it. Replaced by cold air sinking from above.
Not directly. When a cold air mass plows into a warm air mass it produces a cold front. Thunderstorms can form along cold fronts. Given a few other conditions these thunderstorms can produce tornadoes.

The air inside a tornadic thunderstorm (a storm that produces a tornado) does spin. But it is that spinning air that causes the tornado, rather than the tornado starting the air spinning.

Tornado
Yes. When a tornado forms, hot and cold air come together. They spiral around each other at a great speed, which is known as torsion.
