Natural Disasters

Tsunamis

A tsunami is caused by sudden movements on the ocean floor , either from earthquakes , volcanoes or underwater landslides . Also they are massive waves that sweep across the ocean and onto land , which destroys many lives and buildings . The waves are that strong and fast that they go faster than a jet plane . About 90 percent of tsunamis occur around the ring of fire , it kills more than 225 , 000 people in 14 countries .


TSUNAMIS ARE DEADLY AND IS A NATURAL DISASTER .

Tornadoes

Tornadoes are natural disasters that destroys many lives and buildings . A strong tornado can pick up a house and move it a block down . Also a Tornado is a rotating , funnel shaped cloud that gets larger from a thunderstorm . Tornadoes are most likely to occur between 3pm and 9pm , but can occur any time .

Floods

A flood is a natural disaster that wrecks houses , buildings , peoples lives and animal lives . It occurs when their is very hard rain and overflows a river or stream . Most Floods take hours even days to develop / clear . The yellow river ( Huang He ) in China has had the four most deadliest floods in the world , it killed 1 to 4 million people .


FLOODS ARE DEADLY AND IS A NATURAL DISASTER .

Volcanoes

Volcanoes are openings in the Earth 's surface , when they are active they let out ashes , gas and hot mamba sometimes it makes a spectacular eruption . Most volcanoes happen around the ring of fire , about 75 % of the volcanoes on Earth are found there . There are also volcanoes found on the ocean floor or even under icecaps , such as those found in Iceland . The Earth's crust is made up of huge plates which fit together like a jigsaw puzzle . Between the Earth's crust and mantle is the magma which is made of rock and gases .


The Effects of Volcanoes :

  • Buildings are destroyed and people are homeless
  • People get killed
  • Poisonous gases kill people and animals


VOLCANOES ARE DEADLY AND IS A NATURAL DISASTER .

Earthquakes

An Earthquake is when two tectonic plates rub together to make a shaky movement . It is measured on a Richter Scale and then it shows the magnitude . The most powerful earthquake that has ever been recorded on Earth was in Valdivia , Chile . Occurring in 1960 , it had a magnitude of 9.5


Earthquakes destroy many buildings and people get killed a lot .

EARTHQUAKES ARE DEADLY AND IS A NATURAL DISASTER .

Droughts

Droughts are natural disasters and they are unsafe to humans , animals , buildings / houses . It occurs when there is no rain , snow , hail etc . Droughts can take days , hours , months even years to develop / clear also it is difficult to predict when it will occur . Things change in the environment because of droughts like climate , ocean temperatures and the lands .


Effects of droughts :


  • Droughts can be very dangerous for people who live in areas with no food and water .
  • It also means that farmers lose money .
  • When a area has a lack of food , water and is poor , the area could have huge arguments / be mean to which people get good , then will sometimes come into a WAR .



DROUGHTS ARE NATURAL DISASTERS AND CAUSE LOTS OF TROUBLE .

Landslides

Landslides take place when pebbles , dirt and rock slide down a hill . Sometimes their small and hard to spot . But other times landslides can be serious and super easy to spot so keep a look out . The most landslides occur in California . Lots of mountains are built weak in California which makes the dirt , pebbles and rock slide down easier , which creates a landslide . Geologists are not happy with the weak mountains in California .


LANDSLIDES ARE NATURAL DISASTERS AND CALIFORNIA BETTER WATCH OUT ! .

Monsoons

Monsoons travel in countryside areas and is very dangerous . Monsoon rains cause floods and landslides , it destroys villages , towns , properties and lives . Monsoons usually occur between April and September . The countries that gets mostly effected is India , Sri Lanka , Bangladesh , Myanmar and Nepal .
