2 )They are not nearly destructive than hurricane. They have fantastic power that they can carry of people , cars and even buildings.
3 )Tornadoes cover an area of a few hundreds metres wide.
4 )Tornadoes are also called twisters.
1)Hurrican winds actually blow much slower than tornadoes. The fastest hurricanes wind speeds are little more than half as great , they can reach a speed of 240 kph or they can reach a speed of just 118 kph.
2)They are more destructive than tornadoes. They can destroy whole countries in just hours.
3 )Hurricanes may cover an area of 800 kilometres across.
4 )Hurricanes are also called cyclones or typhoons.

2 .How can we save lives? By using
By using space satellite pictures that give information to storms Forecast Center .
3 .How can technology save lives?
It gets information from weather balloons, weather stations and satellite pictures .
4 .Where does storms Forecast Center get information from?
If you have much money. This means you have a car or a plane. When a disaster happens, you can escape from it by using the car or the plane .
6 .How can wealth save lives?
