3. Whаt is аnоther nаme fоr tоrnado in paragraph 2? 2. Tornadoes, also called twisters, are columns of air rotating dangerously fast. The air is in motion because of the difference in pressure between the center of the tornado (very low pressure) and the outer edge of the tornado (high pressure). Some tornadoes are quite narrow — only 75 meters (250 feet) across where they touch the ground. Other, much more massive tornadoes can be up to two miles across. Often a tornado will touch the ground for only a few minutes and travel less than a mile. But some tornadoes touchdown for much longer, plowing through towns, neighborhoods, or farms. [BLANK-1]
