- Good Morning My Dear Friends And Teachers, Today We Will Talk About natural disasters, So Lets Begin, Natural disasters include Tornadoes ,Cyclones, Waves, Flood etc. Sea Disasters Are Normally Caused By tectonic plates moving in the ocean ,and tectonic plates move 2-5 cm per year, But When One Tectonic Plate gets stuck against one another then it can't move but it generates pressure and it comes to a point where one tectonic plates moves so much causing an earthquake.
- So Now Let's Talk About Tornadoes ,Tornadoes Form When Warm, humid air collides with cold, dry air. The Denser Cold Air Is pushed over the warm air, usually producing thunder storms. the warm air rises through colder air, causing an updraft. the updraft will begin to rotate if winds vary sharply in speed or direction.
