The biggest reason why flooding oocurs in Bangladesh is because its REALLY below sea level.  Also they don't have the money to bulid up nice dams or other safety measures needed unlike other countries or areas.

well, scientists and meteorologists theorise that because of global warming, the ocean's waters are getting warmer and causing more hurricanes and tropical storms to spawn. also, the earth is the warmest it's been in over 2000 years. all you need to know, WE BEAT THE RECORD! :P

Flash floods occur whenever water enters into an area faster than it can be absorbed or drained.\n\nSometimes flash floods occur far away from where the actual rain falls, for example up river, and so can truly cause inhabitants to be surprised.

Well most (but not all) U.S. hurricanes are caused by heated water near Africa evaporating and rising quickly to form a localized storm cell. These occur in regular tropical waves, which is why hurricanes arrive at intervals. The initial storm cell is pushed west towards the U.S.A. by easterly winds and as it moves the storm can pick up more energy from warm water and combine with other unorganized storms, growing in intensity. It becomes a hurricane when it develops multiple cells and its windspeeds are over 74 miles an hour. It then can be pushed around by large air masses and other pressure zones and winds, usually it gets directed northward as it approaches the U.S. because of high pressure zones like the one around Bermuda (the Bermuda high). Depending on the exact location of these pressure zones and their intensities, the hurricane can be directed up early and miss the U.S., or up into Florida, or in the case of Katrina, into the Gulf of Mexico and then up between Mississippi and Louisiana. Once the hurricane comes onshore, it loses energy quickly as water starts to rain out and reverse the low pressure zones at the center and between the cells of the hurricane. It eventually dies but not before causing lots of wind and water (flood) damage.

Brittany, the NCDC (National Climatic Data Center) indicates  8211 different storm events since January 1st of 1995.  If by "natural disasters" you are specifically referring to "weather" disasters, that's the place to go for further information.  You can visit them (and search for further information) at the link below.  Good luck!

Drought and poor water quality are the causes of poverty in the World. Diseases set in with the deaths of populations which just makes things worse. Global Warming has off set the water tables and the rains that provide water to Africa, India, and South East Asia. The Epidemic was started 30 years ago and has ended up in Civil War in Africa.

Very complicated answer - sorry... you'll need to spend time reading these links.  the term is "erosion" - These will get you started.....\n\nhttp://www.igsb.uiowa.edu/browse/glacflds/glacflds.htm\n\nhttp://www.afrol.com/News2002/nig002_floods_erosion.htm\n\nhttp://www.mnr.gov.on.ca/MNR/water/p766.html

Water...\n\n* Liquid water, eg in rivers and coasts (in the sea this is largely caused by the gravitational effect of the moon);\n* Liquid water is a major cause of landslides - soil becomes over-saturated and therefore loses its adhesion to the soil or rock beneath;\n* The action of freeze-thaw where liquid water seeps into cracks, expands when it freezes thereby widening the crack and ultimately splitting rocks apart;\n* Frozen water in the form of glaciers grinding away at mountains;\n\nOther causes of erosion include:-\n* the wind, especially when it blows sand particles with it which erode rocks;\n* the Sun which alternatively heats and cools rocks so that they split in much they same way as freeze-thaw (especially in desert areas);\n* humans - we contribute to many of the above processes by our own actions, eg deforestation prevents the soil from holding as much water so landslides become more likely; over-farming creates deserts which are subject to wind and sun; coastal "management" often results in more rapid erosion of some areas of coastline

Pollution and DDT can cause poor environments.  All the oil and logging industries causes detriment to fishing of salmon for eagles.  As civilization expands their habitat shrinks.

the floods in Bangladesh are prayed for as they bring fertile silt even though they kill loads of people

I have told my chidren this following story.When the world was made the land became dirty and all messy.One day God in heaven decided to clean it up.So he took some water from the ocean and began to sprinkle the world.When he thought it to be clean enough he added a beautiful rainbow.To show that the rain falling from above is a gift to us.Now I tell it to my grandchidren.

flood (in Old English flod, a word common to Teutonic languages; compare German Flut, Dutch vloed from the same root as is seen in flow, float) is an overflow of water, an expanse of water submerging land, a deluge. In the sense of "flowing water", the word is applied to the inflow of the tide, as opposed to the outflow or "ebb". The Flood, the great Universal Deluge of myth and perhaps of history is treated at Deluge in mythology.\n\n \nFlooding in Asheville, North Carolina in July 1916In many arid regions of the world, the soil has very poor water retention characteristics, or the amount of rainfall exceeds the ground's ability to absorb water. When a rainfall does occur, it can sometimes result in a sudden flood of water filling dry streambeds known as a "flash flood".\n\nFlood from sea can cause overflow or overtopping of flood-defences like dikes as well as flattening of dunes or buffs. Land behind the coastal defence may be inundated or experience damage. Floods from sea may be caused by heavy storm (storm surge), high tide, a tsunami or a combination thereoff. As most urban communities are located near the coast, this is a major threat around the world.\n\nMany rivers that flow over relatively flat land border on broad flood plains. When heavy rainfall or melting snow causes the river's depth to increase and the river to overflow its banks, a vast expanse of shallow water can rapidly cover the adjacent flood plain. Flooding deposits silt on the flood plain, improving its fertility. Throughout history, this has attracted agriculture and other human development. In order to preserve these farms and cities, some rivers prone to flooding have had extensive and elaborate systems of dikes constructed along their shores and surrounding nearby cities. Unfortunately, by restraining flood waters, these dikes can result in much greater flooding downstream and in locations where they break. Because off the dikes the difference between water-level during flood and the surface of the inland increases and the potential devastation of the flood increases. The control of annual flooding, by dikes and by dams, also prevents the deposition of silt on the rich farmlands and can result in their eventual depletion. The annual cycle of flood and farming was of great significance to many early farming cultures, most famously to the ancient Egyptians of the Nile river and to the Mesopotamians of the Tigris and Euphrates rivers.\n\nA flood occurs when an area of land, usually low-lying, is covered with water. The worst floods usually occur when a river overflows its banks. An example of this is the January 1999 Queensland floods, which swamped south-eastern Queensland. Floods happen when soil and vegetation cannot absorb all the water ; water then runs off the land in quantities that cannot be carried in stream channels or kept in natural ponds or man-made reservoirs.\n\nPeriodic floods occur naturally on many rivers, forming an area known as the flood plain. These river floods usually result from heavy rain, sometimes combined with melting snow, which causes the rivers to overflow their banks. A flood that rises and falls rapidly with little or no advance warning is called a flash flood. Flash floods usually result from intense rainfall over a relatively small area. Coastal areas are occasionally flooded by high tides caused by severe winds on ocean surfaces, or by tidal waves caused by undersea earthquakes. There are often many causes for a flood.\n\nMonsoon rainfalls can cause disastrous flooding in some equatorial countries, such as Bangladesh, due to their extended periods of rainfall. Heavy rain caused substantial damage across eastern Europe in the summers of 2003 and 2005. Normally riverine floods occur only in winter as a result of heavy rain in combination with melting of snow and glaciers in spring.\n\nA flood can also occur when a volcanic eruption melts a large amount of ice and snow quickly.

Yeah, I've also seen all these natural disasters. Even in my country, last year there were about 10 or more floods, and this year one or more. Cause? Global polution, tree cutting.\nSomebody save the earth! plz!

It is a cause of soil erosion but not soil pollution. Soil pollution happens due to untreated water

1) Farming can cause soil erosion: \ne.g. Deforestation removes roots holding soil and allows extensive wind and water damage. \n\n2) Farming causes desertification: \nThis is when a desert gradually spreads to the surrounding areas of semi-desert, making them true desert! \n\n3) Chemical pollution and habitat destruction are major problems: \nCareless use of fertilisers pollutes rivers and lakes, making them green, slimy and horrible. \n\n4) Irrigation can cause environmental problems:\ncreating dams involves flooding large areas. Wildlife habitats are destroyed and people have to be resettled! \n\nHope I helped!
