Have you ever heard of a tornado, little one? Maybe you haven\u2019t seen one in real life, but you might have heard grown-ups talk about it or seen it on TV, right? It\u2019s a powerful spinning wind that can sweep away many things in its path. But why do tornadoes happen? Let\u2019s discover this fascinating secret together with I-CLC!<\/span><\/p>\n L\u1ed1c xo\u00e1y l\u00e0 g\u00ec?<\/b><\/p>\n What is a tornado?<\/b><\/p>\n L\u1ed1c xo\u00e1y l\u00e0 m\u1ed9t <\/span>c\u1ed9t kh\u00f4ng kh\u00ed xoay tr\u00f2n c\u1ef1c m\u1ea1nh<\/b>, k\u00e9o d\u00e0i t\u1eeb <\/span>\u0111\u00e1m m\u00e2y gi\u00f4ng tr\u00ean tr\u1eddi<\/b> xu\u1ed1ng m\u1eb7t \u0111\u1ea5t.

From a distance, it looks like a giant spinning chimney. Inside the tornado are very strong winds that can move quickly and pick up everything in their path.<\/span><\/p>\n L\u1ed1c xo\u00e1y h\u00ecnh th\u00e0nh nh\u01b0 th\u1ebf n\u00e0o?<\/b><\/p>\n How do tornadoes form?<\/b><\/p>\n L\u1ed1c xo\u00e1y th\u01b0\u1eddng h\u00ecnh th\u00e0nh khi th\u1eddi ti\u1ebft c\u00f3 <\/span>gi\u00f4ng b\u00e3o l\u1edbn<\/b>.

At that time, warm and humid air near the ground rises and meets cold, dry air coming down from above. This difference in temperature and pressure causes the air to start spinning. If the wind is strong enough and spins fast enough, it can form a tornado that reaches down to the ground.<\/span><\/p>\n L\u1ed1c xo\u00e1y nguy hi\u1ec3m nh\u01b0 th\u1ebf n\u00e0o?<\/b><\/p>\n How dangerous are tornadoes?<\/b><\/p>\n B\u00e9 t\u01b0\u1edfng t\u01b0\u1ee3ng nh\u00e9, m\u1ed9t c\u01a1n gi\u00f3 xo\u00e1y m\u1ea1nh \u0111\u1ebfn m\u1ee9c c\u00f3 th\u1ec3 <\/span>b\u1eadt g\u1ed1c c\u1ea3 c\u00e2y to<\/b>, <\/span>cu\u1ed1n bay m\u00e1i nh\u00e0<\/b> hay <\/span>l\u00e0m \u0111\u1ed5 c\u1ed9t \u0111i\u1ec7n<\/b>, \u0111\u00f3 ch\u00ednh l\u00e0 s\u1ee9c m\u1ea1nh c\u1ee7a l\u1ed1c xo\u00e1y!

That is the power of a tornado. Tornadoes do not just damage buildings and objects. They also make it dangerous to travel and can harm both people and animals.<\/span><\/p>\n![\"\"](\"https:\/\/i-clc.edu.vn\/wp-content\/uploads\/2025\/08\/3.jpg\")
