really big hurricanes can span 1‚127 kilometers. The size of a hurricane is not directly related to its wind speed or force. Small ones can be extremely strong‚ while big ones can be relatively mild. The spiraling winds of the most powerful tornados can reach a speed of about 320 miles per hour‚ the most violent winds on earth. This is faster than airplanes could fly‚ faster than a formula one race car‚ and almost half the speed of sound. However‚ most tornadoes range at less than 200 miles

What’s the weather like? Windy! 1. Windy systems are produced by two fundamental forces: the heat of the sun and the spinning of the earth. By heating the atmosphere‚ the sun affects the patterns of air pressure around the globe. Because of the earth’s position in relation to the sun‚ different parts of the atmosphere are heated more or less‚ according to the time of the year. High and low air pressure areas form and air constantly moves to reduce the former and lift up the latter. 2. The

An earth quake can be described as a shaking of the Earth’s crust. It is mainly a movement of the whole crust that originates in the center of the earth. Earthquakes happen when the underlying rock suddenly shakes or breaks off. The moving of the underlying rock causes the surface rocks to slide and‚ as a result‚ leads to the earthquakes. Earthquakes can be extremely disastrous and cause a lot of damage in the place where they happen. The earthquake can happen once or happen as a series. This depends

tornadoes is found in Tornado Alley‚ USA. What is a tornado: * A vortex (whirling mass of air)descends from well developed cumulonimbus cloud. * A tornado vortex is in contact with the cloud and the ground * Violent winds (100m per second) * Extreme pressure gradients (25mb per 100m) and air rushing from the high to low causes the spinning winds. (Hurricanes 20mb per 100km!!) * Diameter of funnel is rarely more then 200m Key conditions required for a tornado to form: *
