What are floods and how do they occur?
Floods are the most frequent type of natural disaster and occur when an overflow of water submerges land that is usually dry. Floods are often caused by heavy rainfall, rapid snowmelt or a storm surge from a tropical cyclone or tsunami in coastal areas.
What do floods leave behind?
Deposited Sediment & Silt Flood waters carry along with them sand, silt, and other debris as they travel. Floods can leave behind large amounts of silt and other debris that can make travel difficult and can be costly to remove.
What causes a flood to occur?
Flooding is an overflowing of water onto land that is normally dry. Floods can happen during heavy rains, when ocean waves come on shore, when snow melts quickly, or when dams or levees break. Flash floods occur when heavy rainfall exceeds the ability of the ground to absorb it.
How do floods affect animals and plants?
How do floods affect animals? Like people, animals can get displaced during a flood. Many animals die during a flood because their habitats have been destroyed. Pests and wild animals such as snakes may migrate to densely populated areas and cause much havoc.
What diseases are caused by Floods?
Floods can potentially increase the transmission of the following communicable diseases: • Water-borne diseases, such as typhoid fever, cholera, leptospirosis and hepatitis A. • Vector-borne diseases, such as malaria, dengue and dengue haemorrhagic fever, yellow fever, and West Nile Fever.
Where do Floods happen the most?

What are 5 causes of floods?
Causes of Floods
- Massive Rainfall. Drainage systems and the effective infrastructure design aid during heavy rains.
- Overflowing of the Rivers.
- Collapsed Dams.
- Snowmelt.
- Deforestation.
- Climate change.
- Emission of Greenhouse Gases.
- Other Factors.
How does flooding affect plant life?
Water in soil (water-logging) or above the soil surface (flooding) means there is much less oxygen available to plants. So, one effect of low oxygen is drastically reduced metabolism, which can sharply reduce yield and, if long enough in duration, cause death to a portion or the entire plant.
What are the 3 main causes of floods?
What Causes a Flood?
- Heavy rainfall.
- Ocean waves coming on shore, such as a storm surge.
- Melting snow and ice, as well as ice jams.

How does eating processed foods affect your body?
For example, thiamine and biotin help to utilize blood sugar by bringing glucose into the energy powerhouse of the cell-the mitochondria-to be burned for energy. Eating refined, processed foods over time can deplete the body of essential nutrients needed for it to function properly.
How does cooking affect the nutrient content of foods?
In fact, boiling reduces vitamin C more than any other cooking method. Broccoli, spinach and lettuce may lose up to 50% or more of their vitamin C when boiled ( 4, 5 ). Because vitamin C is water-soluble and sensitive to heat, it can leach out of vegetables when they’re immersed in hot water.
How are nutrients lost when food is processed?

Can corrosion. Food reacts chemically with the metal container, especially high-acid food like canned tomatoes and fruit juices. Over several years, this causes taste and texture changes. It eventually lowers the nutritional value of the food. Temperatures over 100 degrees F are harmful to canned foods.
