Hope that it will help you!!
Explanation:
A flood is an overflow of water onto land that is normally dry. Floods can happen almost anywhere. They can cover an area with just a few inches of water or they can bring enough water to cover the roof of a house. Floods can be dangerous for communities, lasting days, weeks or sometimes even longer.
Many different situations can cause a flood. Here are just a few:
Heavy rainfall
Ocean waves coming on shore, such as a storm surge
Melting snow and ice, as well as ice jams
Dams or levees breaking
Geography can also make an area more likely to flood. For example, areas near rivers are often at risk for floods. Urban areas (areas near cities) are also at higher risk for floods because rooftops funnel rainfall to the ground below, and paved surfaces such as highways and parking lots prevent the ground from absorbing the rain.
Answer:
Explanation:
As we mentioned before, river flooding can happen when there is debris in the river or dams that block the flow of the water. ... Storm surge and tsunamis also cause flooding. Storm surges from hurricanes and other tropical systems can cause sea levels to rise and cover normally dry coastal areas in several feet of water.
