I.Types of Natural Disasters

On Earth, there are numerous types of natural disasters such as tsunamis, earthquakes, thunderstorms, tornadoes, etc. Some occur more than other natural disasters, while others cause more destruction than others. Natural disasters form because of the shifting of earth, the weather, and floods and mudslides.

A.. Most Common Natural Disasters There are some natural disasters that occur more than others. Some examples of most common natural disasters are hurricanes and thunderstorms. Even though these disasters are more common than others, they can cause more damage.

Hurricanes

Hurricanes are a storm of the most intense severity (dictionary.com). Hurricanes develop when seawater comes above

B. Least Common Natural Disasters

There are also natural disasters that occur commonly, but can cause a magnificent amount of damage. Some examples of least common disasters are volcanoes and heat waves. Even though volcanoes occur less, they create mass damage. A volcano is a vent in Earth’s crust. What causes volcanoes to erupt is that when magma rises closer to the Earth’s surface, the pressure decreases and the dissolved gases come out of the solution to form bubbles. Then as the bubbles expand, the magma is pushed into the vent until it breaks through weaknesses in the Earth’s crust. There are 3 types of volcanoes. Sleeping volcano, Shield cone volcano, and a stratovolcano. They are different because a sleeping volcano doesn’t have volcanic activity, a shield volcano has runny lava that erupts from the vent in a gushing river, or fountain, and a cinder cone volcano has one vent that erupts ash and rocks that fall in a ring, and a stratovolcano erupts thick, sticky lava that cools and hardens
