HURRICANES
This type of storm system rotates around a low-pressure center and forms exclusively over warm ocean waters
tropical cyclone
When magma is erupted it becomes...
lava
The difference between slow-developing floods and flash floods in terms of time scale.
flash floods develop rapidly, while slow floods last days or weeks
The slow movement of these large sections of the Earth’s crust is the main cause of earthquakes
tectonic plates
definition of a landslide
The downward movement of soil, rock, or debris along a slope due to gravity
The hurricane classification scale that is based specifically on sustained wind speed rather than rainfall or storm surge.
the Saffir–Simpson Hurricane Wind Scale
This region surrounds the Pacific Ocean and is characterized by frequent earthquakes and explosive volcanic activity due to the interaction of multiple tectonic plates
he Pacific Ring of Fire
A major health risk associated with floods caused by water contamination
spread of diseases
The sudden release of this stored energy causes the ground to shake
seismic energy
A natural factor that reduces slope stability and can trigger a landslide
heavy rainfall
Name two major long-term consequences of hurricanes on coastal regions
economic decline and long-term environmental damage to coastal ecosystems
A steep-sided volcano built from alternating layers of lava, ash, and volcanic debris.
a strato-volcano
what is a flood that follows a hurricane called?
a storm surge
the technology used t detects earthquakes
seismograph
Two natural events mentioned in the slides that can directly trigger landslides.
earthquakes and volcanic activity
The minimum sustained wind speed required for a tropical storm to be classified as a hurricane
119 km/h (74 mph)
Volcanic materials that can cause immediate casualties even without lava reaching inhabited areas.
ash clouds and pyroclastic flows
Two natural processes, other than rainfall, that can cause floods
snowmelt and river overflow
Countries frequently affected by earthquakes because they lie on active plate boundaries.
Japan, Chile, Turkey, and California
Areas that are especially vulnerable to landslides according to the slides.
steep slopes and unstable hillsides
The calm, low-pressure center of a hurricane, often surrounded by the most violent winds
the eye of the hurricane
This type of volcano is characterized by wide, gently sloping sides formed by low-viscosity lava flows
a shield volcano
This catastrophic flood occurred in China in 1931 and is considered one of the deadliest natural disasters in history.
Yangtze River floods
Name at least 4 tectonic plates and where they are located
pacific plate, southamerican plate, eurasian pate indo-australian plate, antarctic plate, african plate, northamerican plate, nazca plate, rabian plate, cocos plate.....
technical term to describe the top and the bottom of a landslide
zone of depletion and zone of accumulation
