No, this isn’t some comic book nonsense or something from an old-world religion. Some climate scientists postulate that the clouds form from the unique combination of sea breezes and humidity changes, but so far, no computer models have been able to accurately predict this odd weather event. Other than Aboriginal myths, not much is understood about why or how morning glory clouds form. The Aboriginal people in the area explain that the cloud is an omen predicting an increase in the bird population. Reaching lengths of over 965 kilometers (600 mi), these vapors are most often witnessed in Australia during the transition from the dry to wet season. Morning glory clouds are long, tube-shaped clouds that travel across the sky rather ominously. Because clouds are made of water, we can understand their shapes and movements and use this data to help predict future weather-at least most of the time. They are made of evaporated water and would (presumably) be very unpleasant to fall upon, unlike the aforementioned pillows. The problem with this idea is that the jelly has been shown to contain no plant or animal DNA, further adding to its long list of perplexing aspects.Īs pillow-like as they appear, clouds are not soft and fluffy. Some believe the jelly to be frog ovum that has expanded from exposure to water. Of course, scientists must have studied this weird element to discover its origin, right? Well, kind of. Documentation of the strange substance dates back to the 14th century, when doctors were known to use the star stuff to treat abscesses. Many have reported seeing the substance fall from the sky, leading to myths that the material comes from dying stars, alien excrement, or even government drones. Star jelly is a translucent gelatinous material, often found in grass or on trees, that is known to evaporate soon after being witnessed. Oddly enough, despite how accurately we can track and predict precipitation, there is something that has fallen from the air that we have absolutely no knowledge of: star jelly. No, these aren’t the four elements, but they are virtually everything one would expect to fall from the sky at any given time. The earthquake, which magnitude is higher than 7 on the Richter scale, is highly destructive.Rain, snow, sleet, hail. The power of an earthquake is expressed in terms of a magnitude and measured on a scale known as Richter scale (as shown in the image given below). The earthquakes mostly are caused by the movement of earth’s plates (as shown in the image below).Įarthquakes are also caused by volcanic eruption/activity, when a meteor hits the earth, or an underground nuclear explosion. The last major earthquake occurred in India on 8 th October 2005 in Uri and Tangdhar towns of North Kashmir and before that a major earthquake occurred on 26 th January 2001 in Bhuj, Gujarat. The major earthquakes are rare, but very much destructive. If a thunderstorm occurs there is also a possibility of lightning and cyclones.Īn earthquake is a sudden shaking or trembling of some region of the earth for a very short time.Īn earthquake is normally caused by a disturbance originated inside the earth’s crust.Įarthquakes keep occurring almost all the time, all over the earth, but most of them are not even noticeable. The metal columns used during the fixing of electrical wires and water pipes in the buildings also protect from the thunderstorm and lightning. The device, used to protect buildings from the effect of lightning, is known as Lightning Conductor.Ī metallic rod, taller than the building, is fixed in the walls of the building from top to toes during its construction protects from thunderstorm (as shown in the image given below). The process of electric discharge also occurs between two or more clouds, or between clouds and the earth (as shown in the image given below).ĭuring the lightning and the thunderstorm no open place is safe.Įlectrical appliances such as computers, TVs, etc., should be unplugged however, electrical lights can be left on, as they do not cause any harm. When negative and positive charges meet, it produces streaks of bright light and sound and the process is known as an electric discharge. The process of transferring of charge from a charged object to the earth is known as earthing. Some natural phenomena can cause large scale destruction of human life and property. When charges move, they constitute an electric current. When a plastic comb is rubbed with dry hair, it acquires some charge and the object is known as charged objects. are the natural phenomena.īenjamin Franklin, an American scientist, showed that the lightning and the spark from clothes are essentially the same phenomena.
