Question

Which statement is not correct with respect to the formation of a tornado?

Select one:
A. the wall cloud forms as the supercell draws in the high humidity air from the forward flank downdraft of the storm that rotates as it hits the ground. This forms a "wall" around the tornado as it forms.
B. the rear flank of the storm curls around the updraft and supplies the rotating air that forms the tornado. On radar this feature creates the hook echo
C. As the storm's updraft stretches upward, the rotation in the storm tightens causing the storm to spin faster.
D. the source of the tornado's rotation comes from the collision of cold Canadian air and warm moist air from the Gulf of Mexico.

Answer 1

A

Step-by-step explanation:

A thunderstorm only occurs in cumulonimbus cloud.

A change in the wind direction and high speed winds at high altitudes makes the air to swirl around horizontally .

The air which rises from the ground tries to push up the air which is swirling around and tips it over.

The funnel of the air starts sucking up more warm air from the ground.

The funnel grows longer and longer and stretches to reach the ground and

when the funnel reaches the surface it becomes a tornado.
