The world can be a dangerous place to live in. In every part of the world, different disasters have devastating effects on lives and geography. below we have introduced some of the natural disasters and what can cause a natural disaster.
Hurricanes are cyclones or typhoons, depending on the region. They consist of an eye at their center, surrounded by a vortex of wind and rainstorms. Hurricanes form when groups of thunderstorms drift over warm oceans; this causes air to rise below and creates low pressure near the surface during atmospheric circulation. This pulls cooler air downwards towards warmer waters, where it rises again in another cycle that can continue for days before they dissipate into nothingness-a process called “heat cycling.” The storm moves across the ocean. As this process continues, the speed of the wind increase.
Tornadoes are also known as whirlwinds, twisters, or cyclones. They form when humid air is heated and starts to rise. As this moist air meets the cold air, it can create thunder clouds which may cause the tornado to funnel from the bottom of these dark stormy skies! Tornadoes can last somewhere between a few seconds to more than an hour before dissipating. On average, the United States has more tornadoes than other countries, but they are found worldwide!
Sudden jolts in tectonic plates cause earthquakes. The Earth’s crust is broken up into several pieces that rest on a semi-molten layer called the mantle. Uneven heating in the mantle causes convection currents which cause the tectonic plates to move, and when they become large enough, earthquakes can destroy whole cities–but these mainly occur around fault lines.
Tsunamis can occur from explosions, earthquakes, volcanic eruptions, under the ocean. These seismic waves can jolt the seabed and cause vast amounts of water to be displaced in oceans as they spread outwards towards shallow coastal areas where it slows down but grows even taller than before. When these tsunamis reach land, a lot more destruction occurs because of their tremendous power and height, which has increased exponentially by this point due to being slowed down at shallower depths near shorelines.
