May people live in dense, dirty areas where narrow, shallow rivers are located. There is potential risk of flooding, which might be caused by both humans and nature. Human bad habits are some of the main causes of flooding. People throw garbage and trash in the river. The flow is blocked and conswequently, the water spills onto the land.

In addition, natural phenomena may result in dangerous floods. Naturally, floods happen when rain is extremely heavy, over an unusually long period of time. In some cases, areas that experience a great deal of snow in winter are prone to springtime flooding when the snow and ice melt, especially if the thaw is relatively sudden. Rainfall and melted snow can sometimes combine to cause floods.

A unique combination of factors sometimes also causes of floods. For instance, whenever the ocean is at high tide, a low-lying coastal area is a risk of flooding. Exceptionally high tides may be attributed to storms, caused by a combination of factors., like low barometric pressure and high winds.

Finally, floods can occur regardless of the climate. Example are volcanic heating and rapid melting of snow pack atop a volcanic mountain or under a glacier, or even failures of natural or man-made dams, and tsunami, seismic waves on the sea or large lakes that are caused by earthquake.

Earthquakes happen when the platesor rocks underground suddenly break or move. That causes seismic waves that result in the ground shaking. When two plates meet, they stick and push against each other. The plates constantly push and after a while, they break. When they plates break, the earthquake occur. Earthquakes usually last for about ten to thirty seconds. The point where earthquakes originate is called the epicenter.

Volcanic eruptions are the most dramatic effect produced by mountains. These eruptions causes disasters, such as wiping places and killing people.

The volcano erupts gently when the magma is low in gas and silica (silicon dioxide, found in sand and rocks). On the other hand, the volcano erupts violently when the magma is rich in gas and silica.

There are four phrases of volcano results thick lava, clouds of gas, and fine ash. They flow at formidable speed.

Therefore volcanic eruptions often have resulted in enormous death and destruction.

There is ... on the magma, so the volcano erupts violently.

A tsunami is a very large sea wave that is generated by a disturbance along the ocean floor. This disturbance can be an earthquake, a landslide, or a volcanic eruption. A tsunami is undetectable far out in the ocean, but once it reaches shallow water, this fast travelling wave grows very large. Tsunamis occur when a major under the ocean floor suddenly slips. The displaced rock pushes water above it like a giant paddle, producing powerful water water waves at the ocean surface. The ocean waves spread out from the vicinity of the earthquake source and move across the ocean until they reach the coastline, where their height increases as they reach the continental shelf, the part of the Earth’s crust that slopes, or rises, from the ocean floor up to the land. Tsunamis wash ashore with often disastrous effects such as severe flooding, loss of lives due to drowning, and damage to property.

Many floods are directly related to weather change. Flooding is caused by extremely high rates of rainfall or an unusually long period of rain. Additionally, areas that experience a great deal of snow in winter are prone to springtime flooding when the snow and ice melt, especially if the thaw is relatively sudden. Furthermore, rainfall and snow melt can sometimes combine. To cause floods.

Flood also occur as a result of a unique combination of factors that only indirectly involve weather conditions. For instance, a low-lying beach area has the potential to flooding whenever the ocean is at high tide. Exceptionally high tides may occur due to storms caused by a combination of factors, like low baromatics pressure and high winds. Finally, floods sometimes can occur regardless of the climate. Seismic waves on the sea or large lakes that caused by earthquakes are some examples. Volcanic heating and rapid melting of snow atop a volcanic mountain or under a glacier, or even failures of natural or man-made dams are other examples.
