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.

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.

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. Flood Facts, Types of Flooding, Floods in History In terms of lives lost and property damaged, floods are just behind tornadoes as the top natural disaster.

Floods: 10 of the deadliest in Australian history THE DEVASTATING NATURE OF recent floods in Australia have meant that they often hit the headlines. While Australia is described as the driest inhabited continent on Earth, right now it might seem hard to believe. Between 1852 and 2011, at least 951 people were killed by floods, another 1326 were injured, and the cost of damage reached an estimated $4.76 billion dollars. Floods can devastate local communities, but they also impact the entire economy - examples include the flood levy imposed in taxes following the south-east Queensland floods in 2010/2011, and also inflated banana prices after the same floods destroyed 75 per cent of the crop. Professor Jonathan Nott, a palaeohazards expert at James Cook University in Cairns, says part of the problem is that we "continue to build in the path of floods," regardless of history, and allow populations to increase in low-lying floodplains.
