Tornadoes are formed when ____
A
rain meets snow
B
hot air meets cold air
C
water meets wind
D
different cloud types collide
Explanation: 

Detailed explanation-1: -A “front” form between a cold air mass and a warm air mass. Sometimes a cold air mass move in above the warm air.

Detailed explanation-2: -The Short Answer: Inside thunderclouds, warm, humid air rises, while cool air falls–along with rain or hail. These conditions can cause spinning air currents inside the cloud. Although the spinning currents start out horizontal, they can turn vertical and drop down from the cloud–becoming a tornado.

Detailed explanation-3: -When warm, moist air collides with cold, dry air, tornadoes emerge. Generally, thunderstorms form when cooler, denser air is pushed over warmer air which is the cause of tornadoes. Updrafts are caused by warm air rising through the cold air. Whenever the wind strength or direction changes, the updraft begins to rotate.

Detailed explanation-4: -The key atmospheric ingredients that lead to tornado potential are instability-warm moist air near the ground, with cooler dry air aloft and wind shear-a change in wind speed and/or direction with height.

Detailed explanation-5: -How a Tornado Forms. The first thing that is needed to produce a tornado is a thunderstorm. To create a thunderstorm you need to have three things, the first of which is a mass of unstable air, which is the result of warm moist air in the lower atmosphere and cold dry air in the upper atmosphere.
