How Tornadoes Form

The video explains the formation of tornadoes, focusing on supercell and non-supercell types. It details the step-by-step process of tornado formation, starting with the heating of the land surface by the sun, leading to air rising and mixing with cooler air. Wind shears play a crucial role in setting off the spinning winds, which grow in size and power, eventually forming a vortex. The tornado becomes fully formed when it touches down, moving in the direction of the storm winds and causing destruction along its path.

What distinguishes supercell tornadoes from non-supercell tornadoes?

• Supercell tornadoes are less powerful.

• Supercell tornadoes have powerful updrafts.

• Non-supercell tornadoes are more common.

• Non-supercell tornadoes form over water.

What initiates the formation of tornadoes according to the video?

• The heating of the land surface by the sun.

• The cooling of the ocean surface.

• The collision of two cold air masses.

• The presence of a high-pressure system.

How does the faster moving wind affect the smaller wind during tornado formation?

• It causes the smaller wind to dissipate.

• It merges with the smaller wind to form a hurricane.

• It spins and rolls over the smaller wind.

• It slows down the smaller wind.

What is the result when the spinning winds gather enough energy?

• They create a vortex of whirling air.

• They form a hurricane.

• They cause a thunderstorm to weaken.

• They dissipate into smaller winds.

What happens when a tornado reaches the ground?

• It changes direction randomly.

• It dissipates immediately.

• It continues moving in the direction of the storm winds.

• It stops moving and remains stationary.
