What are Natural Disasters?Natural Disasters are disasters that occur in this world naturally.Natural disasters can happen at any location at any time throughout the universe. Natural disasters can destroy cities, or sometimes a whole country if it is that severe. They can occur on land, in the water, and with the weather.
What are land movement disasters? Land movement disasters are disasters that occur on land. Some land movement disasters are earthquakes, avalanches, volcanic eruptions, wildfires, landslides and many more.
Avalanches Avalanches are rapid downhill flow of a large mass of snow or ice dislodged from a mountainside or the top of a high cliff, or a similar fall of rocks and earth.
Avalanches are usually downhill fall of snow or mud but sometimes it may get mixed up with mud.
Volcanic EruptionsA volcano is an opening in the planets surface which lets hot, rocks, ash, molten lava, and gases onto the surface from inside the planet. Volcanic activity involving the extrusion of rock intends to form mountains over a period of time.Volcanoes are found where tectonic plates are either diverging or converging. A volcanic eruption is when a volcano erupts and lets out lava, rocks, ash, and many more things. These things that are let out during a volcanic eruption are from the inside of the planet. Volcanoes can form where there is stretching and thinning of the planets crust or surface.
WildfiresWildfires are common in different parts of the world and they happen in cycles. They are useful in the wilderness sometimes because the effects of the fires help some species with growth and reproduction. Nine out of ten wildfires are caused by humans interaction.Wildfires are when fire is spreading quickly. A wildfire is a fierce fire that spreads rapidly and mostly in an area of wilderness A wildfire is any uncontrolled fire which occurs in wilderness, wild lands, or bushes. Another word to say wildfire can be bushfire, hill fire, and many more things can be the same meaning as a wildfire. Wildfires means something furious or destructive.
EarthquakesEarthquakes are shaking of the Earths crust. An earthquake is a violent shaking of the Earths crust that may cause destruction to buildings and cities.Earthquakes are caused mostly by rapture of geological faults, also by volcanic activity, landslides, mine blasts, and nuclear experiments.Some earthquakes that happened before are the Haiyuan earthquake in 1920 which happened in China, Messina earthquake in 1908 which happened in Italy, and the Quito earthquake in 1797 which happened in Ecuador.
Water DisastersWater Disasters are disasters that occur in water such as oceans, rivers, lakes, etc.Some types of water disasters are droughts, tsunamis, tidal waves, floods, and many more.
DroughtsDroughts are long period of extremely dry weather when there is not enough rain for the successful growing of crops or the replenishment of water supplies.
FloodsFloods are water covering previously dry area.A flood is a very large amount of water that has overflowed from a source such as a river, lake, and ocean. They can also have overflowed a broken pipe onto a previously dry area. The damages after a flood is harsh because everything or parts of things will be under water and the effects of a flood can kill many people.
TsunamisTsunami is a large destructive ocean wave caused by an underwater earthquake or some other movement of the earths surface. A tsunami is a series of waves created when a body of water is quickly displaced. Earthquakes, and volcanic eruptions, may happen underwater or above water which causes a start of tsunami in the oceans, rivers, or coastlines. Tsunamis can savagely attack coastlines, causing devastating property damage and loss of life.Tsunamis are sometimes called tidal waves because they may resemble a non-lunar-tidal rush of rapidly rising water, rather than big cresting waves reaching the shore. Some tsunamis are in the Indian Ocean which happened with a earthquake as well.
Weather Disasters Weather disasters are disasters that occur with the weather and causes changes in the weather. Some types of weather disasters are tornadoes, cyclones, hurricanes, blizzards, lighting, thunderstorms.
Hurricanes Hurricanes are several tropical storms that can form in the Atlantic Ocean, Caribbean Sea, Gulf of Mexico, and in the Pacific Ocean. Hurricanes gather heat and energy through contact with warm ocean waters. Hurricanes are named so people can spot and identify them while they move across the ocean. Hurricanes that occur at the seas, and oceans cause large waves, heavy rain, and high winds. These things can cause destruction to international shipping and may cause many shipwrecks. Tropical cyclones is another name for hurricanes when it is at a certain level or at a certain size. Some hurricanes that have occurred are the Bombay Hurricane in 1882 in India, and Hurricane Katrina which happened in the United States.
Lighting storms and ThunderstormsLighting storms and thunderstorms are basically the same thing.They both contain flashes of lighting striking an area and the effects of the lighting causes thunder.Sometimes during these storms, it also rains, snows or hails in certain cases. A lighting is caused when a electrical charge is contained in a cloud and then releases it on the earths surface. The temperature of a lighting bolts is extremely hot.
Lighting storms and Thunderstorms
TornadoesTornadoes can happen when there is a thunderstorm. The color of tornadoes ranges from shades of gray, shades of brown, and white. Some times they are not that visible to see. A tornado is a dangerous rotating column of air which is connected to the surface of the earth and a clod. It destroys anything it touches in its path.
Tornadoes are extremely destructive funnel-shaped rotating column of air that passes in a narrow path over land. Tornadoes can come in many sizes and shapes. The usual shape of a tornado is a funnel, which is seeable and is narrow end touches the earths surface.
CyclonesA cyclone is a large-scale storm system with heavy rain and winds that rotate counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere around and toward a low pressure center.Cyclones have also been seen on other planets other then the Earth, such as Mars, and Neptune.Some deadly cyclones that happened before are the Bhola cyclone in Bangladesh in 1970, the India cyclone in India in 1839, the Calcutta cyclone in India in 1737, and the Bangladesh cyclone in Bangladesh in 1991.
