During hurricanes, water rises above the normal tide level.
Earthquakes cause this water to rise higher than its normal tide level.
These waves, which are often caused by landslides, are higher than usual.
Why was Hurricane Katrina especially devastating to the city of New Orleans?

The National Forest Service prohibited people from using campfires.
Congress budgeted money for fighting forest fires.
Yellowstone Park was closed for two years.
What types of changes have been made in the United States to help protect people from earthquakes?
Communities are no longer located along fault lines.
Building codes ensure that structures can withstand shaking.
Warnings go off when an earthquake is expected, and people evacuate the area.
Barriers have been built to prevent flooding by a tsunami.
An earthquake in Alaska was so large it caused ________ that in turn caused a tsunami.
a volcanic eruption
Which of these has seen many floods, including one that lasted for months in 1993?
the coast of New Jersey
the Mississippi River
the Big Thompson River
What made the San Francisco earthquake of 1900 so devastating?
The earthquake lasted over ten minutes.
The earthquake occurred in an area that had poorly built structures.
The earthquake damaged water mains, so fires could not be extinguished.
The earthquake caused a tsunami that flooded the city.
What natural disaster caused included a tsunami and dust that did not fully settle for over a year?
the volcanic eruption of Krakatoa
the Great Japanese earthquake
the Alaskan tsunami
What occurs at transform boundaries?
eruption of hot spots
What formed as a result of a hot spot?
The Mid-Atlantic Ridge
the Hawaiian islands
Mount St. Helens
the San Andreas fault
The Andes Mountains are found along the western coast of South America. What kind of plate boundary is responsible for this mountain range?
The North American plate and the South American plate are at a transform boundary.
The Nazca plate is converging with the South American plate.
The Nazca plate and the North American plate are at a transform boundary.
The North American plate is diverging with the South American plate.
What has formed as a result of diverging plates?
What formed as a result of plates sliding past one another?
Which plate will feel stress in the form of compression?
oceanic plates diverging
oceanic and continental plates at a transform boundary
a central fault in a continental plate
an oceanic and continetal plate converging
A downfold of rock caused by compression is called a _________.
What is a fault?
a type of folding in which the two sides stay in relatively the same place
a type of folding in which the two sides move in relation to one another
a type of fracture in which the two sides stay relatively in the same place
a type of fracture in which the two sides move in relation to one another
When does a fault occur?
A fault occurs when stresses in the crust cause land on one side of a fracture to move in relation to the other side.
A fault occurs when folding in the crust causes land on one side of a fracture to move in relation to the other side.
A fault occurs when folding in the crust causes land on one side of a fracture to stay even with the land on the other side.
A fault occurs when stresses in the crust cause land on one side of a fracture to stay even with the land on the other side.
Which material would a seismic wave travel through the fastest?
How might geologists in China and Australia help geologists in Japan determine where an earthquake has occurred?
By using seismic data from several locations, scientists can determine the epicenter of an earthquake.
Chinese and Australian scientists can go to Japan to help them analyze their seismic data.
Chinese and Australian scientists can study the damage caused in their own countries.
These scientists can determine the earthquake's location by the shaking they feel at their locations.
Where does the energy of an earthquake originate?
heat from Earth's interior
Earth's magnetic field
the building of volcanos
motion of tectonic plates
By analyzing the speed at which seismic waves travel, scientists gain clues about _________.
the elements found in Earth's layers
the amount of magma in Earth's layers
the density of Earth's layers
the temperature of Earth's layers
