Question

__________ are vortices caused by interference to wind by obstruction. They form from the ground upward and are not tornadoes.

Answer 1

Answer:

Whirlwind

Explanation:

A whirlwind is a meteorological phenomenon that implies an accelerated rotation of the wind vertically, forming a whirlpool. The generation of this phenomenon occurs when, in two sectors of a mass of air that travels, there is a difference in speed, which leads to turbulence.

The air, when hitting the ground and encountering different obstacles, begins to form a whirlpool. The rotation of the whirlwind takes place at high speeds, something that partly explains its violence as it passes through the surface of the Earth. In addition, it usually presents a certain stability; This can be seen in the numerous captures that scholars have made over the decades, but also in fiction works in which they appear as cones that destroy everything in their path.

When a whirlwind rubs the ground, or when certain objects disturb it, the creation of several small eddies occurs, even of a diameter much smaller than the meter. These small whirlpools are easy to see on dirt floors, since the dust begins to be part of its body and evidences its rotational movement and the presence of an axial zone without sufficient force to move the solid particles.
