What is a wall cloud? What's the difference between a watch and a warning? Is it ever “too cold to snow”? Learn all about thunderstorms, tornadoes, hail, lightning, floods, damaging winds and severe winter weather. Thunderstorms There can be as many as 40,000 thunderstorms each day around the world. They are most common in the U.S., where they can produce tornadoes, floods, lightning and damaging winds. Learn more → Tornadoes Much about tornadoes remains a mystery. Learn more → Floods Except for heat-related fatalities, more deaths occur from flooding than any other weather-related hazard. Learn more → Lightning Lightning is one of the oldest observed natural phenomena on earth. Learn more → Hail Hail can cause billions of dollars of damage to structures, crops and livestock.

What is an Earthquake. Introduction to Earthquakes & Tsunamis Turn on the TV or read the newspapers and almost always there is something devastating happening somewhere as a result of sheer nature's power. Examples of such natural occurrences are hurricanes, tornados, wildfires, volcanic eruptions, flooding, earthquakes and tsunamis. These are usually not caused directly by humans, but their effects live with us for a long time. In this lesson we shall look at one of such natural occurrences...earthquakes!
What is an Earthquake? Simply, earthquakes are the rumblings, shaking or rolling of the earth's surface. It is usually what happens when two blocks of the earth suddenly slip past one another, or break apart from each other as a result of tension caused by prolonged energy build up. Earthquakes come in many forms. Foreshocks, Mainshocks and Aftershocks: Sometimes, there are smaller shocks that occur before (foreshock) and after (aftershock) a main earthquake (mainshock). Earthquakes are also called temblors. What is a volcano? Introduction to volcanoes The earth's mountains, plains, plateaus, soils, rocks, etc. as we see it today is believed to have gone through many phases, with about 80% of it being carved out by the action of volcanoes.
A volcano is simply a rapture (opening or vent) on the earth's surface (crust) through which molten magma (extremely hot mixture of gases, lava, ash and other burning substances) escape on to the earth's surface. How do Volcanoes look like? A volcano looks like a mountain, although they are two different things.A mountain is a large natural rise of the earth's surface, more like a giant heap of sand. A volcano is also like a big heap of earth just that this heap is a mixture of lava, ash, dust, and other substances that have piled up over many years.
In May 1980, the Mountain St. Volcanoes occur at weak zones or points in the earth’s crust (including constructive and destructive boundaries). Now we shall see in a bit more detail how volcanoes come about. What is a flood? Introduction to Flooding Many of us have this idea that floods (or flooding) is simply, too much water around your house. People think that can be fun. Wrong. Flooding is a lot more than that. Flooding is extremely dangerous and has the potential to wipe away an entire city, coastline or area, and cause extensive damage to life and property. What is a flood? It is a natural event or occurrence where a piece of land (or area) that is usually dry land, suddenly gets submerged under water. When floods happen in an area that people live, the water carries along objects like houses, bridges, cars, furniture and even people. Floods occur at irregular intervals and vary in size, duration and the affected area.
It is important to note that water naturally flows from high areas to low lying areas. In this lesson, we shall see more about what causes flooding, the types of flooding, some effects of floods and what we can do before, during and after floods occur. Quiz Whiz: Volcanoes. Natural Disasters. 1. Most natural disasters are caused by weather. Weather disasters can be caused by hurricanes, tornadoes, floods, tsunamis, thunderstorms, wind storms, wildfires, avalanches, and blizzards. 2. Some of the weather disasters can be predicted such as hurricanes and blizzards. The technology is getting better in predicting tornadoes and severe thunderstorms. 3. 4. 5. 6. 7. 8. 9. 10.

Image copyright Getty Images Earthquakes have claimed hundreds of thousands of lives in the last 100 years, and improvements in technology have only slightly reduced the death toll. 25 April 2015 A 7.8-magnitude earthquake kills more than 8,000 people and leaves hundreds of thousands homeless, in the worst natural disaster to strike Nepal since 1934.
In some parts of the country, the quake flattens 98% of all homes in hillside villages. 3 August 2014 Approximately 600 people are killed in a 6.1-magnitude earthquake that strikes Yunnan province in China. 15 October 2013 More than 200 people are reported to have died after a magnitude 7.2 earthquake strikes centrally-located Bohol and Cebu in the Philippines. 25 September 2013 More than 300 people are killed as a 7.7-magnitude quake flattens entire villages in Pakistan's remote south-western province of Balochistan, mainly in the district of Awaran. 20 April 2013 11 August 2012 23 October 2011 11 March 2011 22 February 2011 14 April 2010 6 April 2009.
What is a drought? What is a drought? The word ‘Drought’ is always a difficult one to define, because it is often used in more than one context. In simple terms, it is the absence of water for a long period of time, at a place where it is considered ‘not normal’ compared to its usual conditions. The distribution of all the water on the earth’s surface is not even. Some places have lots of fresh water (rivers, lakes, lagoons, ponds etc.) and are continuously replenished by rainfall, runoffs and water from underground. Therefore, if a region that has lots of rainfall, goes for a couple of weeks without rains, and people, animals and plants begin to experience a bit of dryness, it can be called drought. With this in mind, we can describe a drought scenario to be ‘A relatively long time where there is not enough water than there usually is, as a result of dry weather, to support human, animal and plant life.
Droughts may not be an issue just because there is less or no precipitation. Information on wildfires for young people. Out of the many natural disasters we have, wild fires would be one that is very common, very difficult to fight, and maybe the most dangerous. What is a fire? Simple, it is the visible part of a combustion.
A combustion is a chemical reaction of three things: Heat, fuel and Oxygen. These three ingredients must be present before a fire can be made and maintained. This is simply a gas found in air. Fuel: Fuel is any kind of combustible material. Heat: Heat is thermal energy. World Book. Convergent Margin—Subduction to Tsunami. Earth 100 Million Years From Now.
