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.
Tornadoes cannot change the shape of the land.
Tornadoes typically form in a warm air mass, as that is what provides the energy, though it is often near a boundary with a cooler or drier air mass. However, due tot he pressure drop the air in a tornado is cooler than its surroundings.

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 power of a tornado comes from the thunderstorm that produces it. A thunderstorm is powered by the energy that water vapor releases when it condenses. Differences in wind speed and direction wind altitude, a condition called wind shear, sets these storms rotating. This rotation can then tighten and intensify to form a tornado.
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.

A tornado.

A tornado produces a greater pressure drop over a shorter distance than a hurricane.
