Volcanoes
what are hotspots?
melting within the upper mantle
Where do Hurricanes form?
warm waters in the ocean
what do tornadoes form from?
thunderstorms
The observation that the continents fit together like puzzle pieces, and may once have been connected, led Alfred Wegener to propose a theory in 1910 called
Continental Drift
where will you find the ozone layer
stratosphere
what are divergent plate boundaries
magma generated from the upper magma
What are hurricanes that form in the Indian Ocean sometimes called
cyclones
Where do tornados mostly form in the United States?
northeast
the development of submarine warfare druing World War II created a pressing need to map the ocean floor. This actually led to research on the ocean floor that would help explain the movement of the continents. What tool was used to do this mapping?
sonar surveys
T/F in the troposphere temperature decreases with altitude
True
what is a volcanoes VEI
measures explosiveness of volcanic eruption
Where is the most dangerous part of the hurricane
Eye Wall
What is a tornado called that forms over warm water?
waterspout
Scientists found that the continents were moving apart from each other due to magma rising out of mid-ocean ridges, and they called this
T/F Earth is the only known planet with a atmosphere
False
where are the majority of the worlds volcanoes
the ring of fire
What is the minimum sustained wind speed a tropical storm must have to be called a hurricane?
74 mph
What measures the intensity of a tornado
Fujita scale
Plate margins are places where much activity occurs. Earthquakes occur, for example, along convergent margins, where plates are
colliding
T/F Carbon dioxide and water vapor are both greenhouse gases acting to warm the atmosphere
True
what type of volcano is Mount Etna
Composite volcano
What do we call the large spirally bands of rain that are generated from a hurricane?
Rainbands
This is a rotating cone-shaped column of air that goes downward from the base of a thunderstorm
Funnel Cloud
Volcanoes occur in similar locations to earthquakes, and are common along plate boundaries. Sixty percent of volcanoes occur surrounding the Pacific Ocean, a location called
Ring of Fire
Pressure decreases rapidly with altitude because the air becomes
less dense
