Cards in this deck (45)
- 1Which is more dangerous and causes more destruction, lava flow, pyroclastic flows, or lahars? And what is it´s effect?Pyroclastic Flows, it destroys almost anything in its path including forests and humans
- 2What volcanic product relates to the hydrosphere? And what is its effectLahars, some effects are floods.
- 3What gas has the highest levels in a volcano?Water Vapor
- 4Which gas is released from a volcano to form acid rain?Sulfur Dioxide
- 5Can you outrun a pyroclastic flow?No, it will destroy almost anything in its path
- 6In preparation for an eruption how many weeks of food should you have?2 weeks
- 7If an eruption is occurring close to you what should you do?Don’t drive, seal up air ways so no ash gets into your house
- 8At what point does an earthquake start?The focus
- 9Is Colorado at risk for Earthquakes?Yes and so are 38 other states in the U.S.A
- 10Do volcanoes and earthquakes occur in the same location every time?No, but they are often close to each other
- 11What does the epicenter represent?The point directly above the focus of an earthquake.
- 12Where do the biggest Earthquakes tend to occur in the U.S.? (Place flag on globe)California
- 13What magnitude of earthquakes tend to cause a landslide?5.2-9.5
- 14In what country had an earthquake recently that cause a big tsunami killing thousands? (place flag on globe)Indonesia
- 15In the case of an earthquake at school what should you do?Go under a desk or a hard surface to protect and cover your head, in case of collapsing of ceilings
- 16What do you do to prepare for a earthquake?Buy flashlights, batteries, food, and live/be in a building that is able to sustain a earthquake
- 17What should you be prepared for after an earthquake?The possibility of an aftershock
- 18What fault in the U.S. is a result of a transform boundary?San Andreas fault
- 19What is the only place on earth that is an example of a continent-continent convergence?Himalayas
- 20What plate does this motion represent? ←→Divergent plate
- 21If an island has a convergent movement what is it automatically?An Ocean-Ocean convergence
- 22How close to accurate are GPS’s?millimeters
- 23What German scientist thought of our continents of puzzle pieces that once fit together?Alfred Wegner
- 24In what way does this picture show that the continents were once together or quite close to one another?It shows how these fossils were found on different continents but the fossil can´t swim across the ocean
- 25The Earth’s mantle is split into two parts, what are those two parts?Lithosphere, Asthenosphere
- 26Is the Earth’s core solid, or does it act more fluid like?Solid
- 27What point is the ocean crust the youngest?In the middle
- 28Where do earthquakes and volcanoes appear on Earth?On plate boundaries
- 29What is paleomagnetism?The magnetic property of rocks
- 30In case of a power outage what device should you have to keep in touch with progress of evacuation, or help?A backup generator, or hand cranked radio
- 31How does an earthquake relate to a rubber band?When enough pressure builds up it will snap and release its potential energy
- 32What ocean does ring of fire go around? (place flag)The Pacific Ocean
- 33What wave makes a front to back motion?P-wave
- 34What wave is the slowest?S-wave
- 35What can a surface wave travel through?Nothing, only on the top of Earth's surface
- 36What is a common continent-ocean convergence?West coast of South America
- 37How does the Earth's materials get created and destroyed?Rocks are destroyed by weathering and reused in making new rocks (the rock cycle)
- 38What wave causes the most damage?A surface wave
- 39Is fire an indirect or direct cause of an Earthquake?Indirect
- 40How did liquefaction get it´s name?It´s because its liquids get into soil causing damage to buildings from the underneath
- 41Why is intensity different from magnitude?Intensity is measured by the damage caused by the earthquake
- 42Is ground shaking a direct or indirect hazard of an earthquakedirect
- 43How does this picture explain why Wegner believed that the continents moved?It shows that glaciers that are found appear to once be connected and are found in odd parts of continents
- 44Where are igneous rocks created?Below the surface (liquid magma) then become solid above the surface after the lava has cooled to created
- 45What steps where made during WW2 for the theory for continental drift?It started to become more believed in, they found the polarity in sea floor lines
