Funnel clouds are the result of rotation in thunderstorms, induced by wind shear, becoming tighter and more intense, stretching toward the ground. If the rotation reaches the ground it is considered a tornado. See the relate question for a more detailed explanation on the formation of tornadoes and the storms that cause them.
The visible funnel itself is a consequence of the pressure drop inside the vortex. Air enterin the vortex experiences a rapid drop in pressure which in turn causes a drop in temperature. This temperature drop causes the moisture in the air to condense into tiny droplets, forming a cloud.

What severe weather in associated with a funnel cloud?
A funnel cloud is associated with severe thunderstorms or tornadoes. It forms when rotating air creates a condensation funnel that extends from the base of the cloud towards the ground. Funnel clouds can develop into tornadoes if the right conditions are present.
What is the relation between a funnel cloud and a tornado?
A funnel cloud is a rotating cloud that extends downward from a thunderstorm, while a tornado is a funnel cloud that has touched the ground. In other words, all tornadoes start as funnel clouds, but not all funnel clouds develop into tornadoes.
Are tornadoes formed by storm clouds or funnel clouds?
Tornadoes are formed by rotating air within a supercell thunderstorm. The rotating air may initially be present in the form of a funnel cloud, which is a rotating, cone-shaped cloud that does not reach the ground. If the funnel cloud extends to the ground, it is then classified as a tornado.
What is funnel clouds that last up to 15 minutes?
Funnel clouds are rotating columns of air that extend downward from a thunderstorm cloud but do not touch the ground. These clouds can develop into tornadoes if they reach the ground. If a funnel cloud lasts for up to 15 minutes, it could indicate a higher likelihood of it touching down and becoming a tornado.
What is a sentence with funnel clouds?

Tornadoes are giant funnel clouds?

Are funnel clouds more common than tornadoes?
Yes. Many funnel clouds never touch down.
To be classified as a tornado funnel cloud must reach to the what?
To be classified as a tornado, a funnel cloud must reach the ground. Funnel clouds that do not reach the ground are typically referred to as non-tornadic funnel clouds.
Where do funnel clouds get their names?
