3 Volcanoes What is a volcano? Volcano are really really hot! They are exceptionally big at the top of the mountain. Lava can role down different ways of hurting people. Volcanoes can be initiated in many variety countries. Volcanoes strength can be unstoppable! Mount Vesuvius was found in Pompeii. Mount Edna is an other one There are about 500 robust volcanoes most of which are found in two main zones: a ‘Ring of Fire’ around the Pacific Ocean and an east-west belt from Europe to Indonesia. M any volcanoes lie underwater on the seabed. T hey form where the earth plates drift apart. T his leaves a crack out of which lava flows. Some undersea volcanoes erupt for a long time. In May 1980,Mount ST Helen’s in Washington, USA erupted with the loss of 60 lives. The side of the cone was blown out by the explosion. Steam can sometimes be seen escaping from the top or sides of a volcano

4 Tsunamis What is a Tsunami?
There are Tsunamis nearly everywhere. Tsunamis are about 100 miles timeconsuming. If you are in a Tsunami you Should climb something in elevation proximately because they are about 3 meters tall. There was a tsunami in the Bahamas on the 14th October 2016.

5 Locations of volcanoes and Tsunamis
f you throw a stone in a pond it will create a series of ripples. A tsunami is just like those ripples but the dance that sets them moving is much greater than a small stone. It can be triggered by an undersea earthquake, landslide or volcanic eruption. In deep water tsunami waves can extend thousands of feet into the sea, and reach speeds of 500mph, almost fast enough to keep up with a jet airplane. There can be up to a hundred miles between each wave, which may be just a few feet above the sea.

6 Hurricanes A hurricane is a huge storm! It can be up to 600 miles across and have strong winds spiraling inward and upward at speeds of 75 to 200 mph. Each hurricane usually lasts for over a week, moving miles per hour over the open ocean. Hurricanes gather heat and energy through contact with warm ocean waters. Evaporation from the seawater increases their power. Hurricanes rotate in a counter-clockwise direction around an "eye" in the Northern Hemisphere and clockwise direction in the Southern Hemisphere. The center of the storm or "eye" is the calmest part. It has only light winds and fair weather. When they come onto land, the heavy rain, strong winds and large waves can damage buildings, trees and cars.
