What is the a natural disaster?

How has technology helped provide relief from natural disasters? (Front page bottom of the page)

• Communication: after natural disasters many countries are able to coordinate food and supplies reliefs.

• Advance Warning Systems: There are many different systems in place to help predict natural disasters.

Multiple Choice

Which of the following is NOT a natural disaster?

• tornado

• hurricane

• tsunami

• car accident

Car Accident

Natural Disasters are not man-made, car accident are man made.

Types of Natural Disasters

• Hurricanes: are giant storms that stretch hundreds of miles and begin at sea and sometimes crash into land.

• Tornados: Spinning funnel-shaped storms with winds up to 300 mph. While tornados may seem small in comparison to other storms but the most violent storms.

• Volcanos: openings in the earths surface where molten magma comes out in violent eruptions or will pour out.

• Tsunamis: Are giant ocean waves that are caused by underwater earthquake or volcano eruptions.

Multiple Choice

Giant storms that begin at sea and sometimes crash into land are called

• hurricanes

• tornados

• avalanches

• mudslides

Multiple Choice

Giant ocean-going waves that are caused by an underwater earthquake or volcanic eruptions are called

• hurricanes

• volcanoes

• tsunamis

• tornadoes

Be Prepared

• Earthquake: stand in a doorway. It is the safest place from falling objects because it is a strong and sturdy frame.

• Tornadoes: go underground cellars are popular by many people, others have tornado shelters being made now.

• Hurricane: tape up windows so that broken glass does not shatter and go flying in the wind.
