NATURAL DISASTERS for kids EARTHQUAKE VOLCÁN TSUNAMI HURRICANE TORNADO WILDFIRE

smile and learn hey friends did you know that nature is in constant process of change we call these changes natural events natural event is an event that occurs in nature and is not directly caused by humans there are many types of natural events such as rain wind or tides when these events become dangerous and destructive we call them natural disasters learning about natural disasters helps us to be forewarned and avoid damages do you want to know more i'll tell you about few of them earthquake an earthquake also called seism or tremor is sudden movement of the earth due to the collision of tectonic plates with each other tectonic plates are like pieces of puzzle that make up the earth's surface that are constantly moving sometimes these tremors are very slight and are not even noticeable but other times they can be very strong and cause personal and property damage we used the richter scale to measure earthquakes strength the largest earthquake ever recorded was 9.6 on the richter scale impressive right volcanic eruption volcanic eruption happens when fissures are formed in the earth's crust and magma comes out of the earth's interior what is magma magma is molten rock at extremely high temperatures when magma leaves the earth's surface we call it lava in addition to magma volcanic eruptions also emit gases and ash that can be harmful to living beings here's an interesting fact 75 of all the volcanoes in the world are located in this area called the pacific ring of fire did you know that volcanic eruptions are extremely powerful and can cause earthquakes tsunami tsunamis are gigantic waves that destroy everything in their path when they reach dry land tsunamis occur for various reasons such as an earthquake or volcanic eruption at the bottom of the sea sometimes tsunamis originate at one point in the world and travel hundreds of miles affecting countries far away from its starting point thanks to international alert systems it is possible to evacuate the areas that will be affected by the tsunami thus avoiding personal damages tornado tornado is tube-shaped mass of moving air that rotates at high speed it usually has wider end at the top and narrower end at the bottom where it touches the ground tornadoes do not usually last long between few minutes and little over an hour and they usually travel several miles before disappearing destroying everything in their path winds that produce tornadoes can reach speeds of up to 300 miles per hour and their average diameter is usually about 250 feet although they can be much larger hurricane hurricanes are the strongest and most violent storms that exist hurricanes are always formed at sea and depending on their location on the planet we give them different names such as cyclones or typhoons hurricane's diameter can be up to 1100 miles also it can last for several weeks generating winds of up to 150 miles per hour which can cause lot of damage when they reach land to measure hurricane's intensity we separate it into different categories from one to five with five being the most dangerous category wildfire wildfire is large fire that spreads out of control and is produced in natural environments such as forests or grassland wildfires can cause great losses in the flora and fauna of the environments where they originate wildfires can be caused by natural causes such as lightning strike or sadly human action flooding floods are accumulations of water in specific locations floods can be caused by different reasons such as excessive rainfall in particular area or an overflowing river there are studies that claim that climate change is responsible for the increase in flooding in certain locations this is why we all have to do whatever we can to take care of the planet earthquakes volcanic eruptions tsunamis tornadoes hurricanes wildfires and floods can be little scary but don't worry thanks to scientific advances it's becoming easier and easier to predict them and thus be able to stay alert and take precautions in the areas where they originate wow we've learned lot about natural disasters today but there are few more to come don't miss the next video we've learned so much in just one video did you know there are many more videos imagine how much you could learn subscribe to the smile and learn educational channel to learn and have fun at the same time
