Except one, others are Effects of Earthquakes, Which one is it?Question 4Answera.Landslides and deep cracks in surface rocks.b.The rise or lowering of the sea floor.c.Provide fertile soil.d.The devastation of cities, fires and diseases.

Which of the following is NOT listed as a potential geologic threat during an earthquake? 2 marksa. Rupture of the earth b. Triggering landslides c. Creation of new islands d. Turning the surface of the earth into liquid

Earthquake is one of the most devastating natural calamities which Blank 1 Question 2 (caused, will cause, had caused, causes) sudden shaking of the earth surface. It, not only causes damage to buildings and other structures but alsoBlank 2 Question 2 (affected, will be affected, had affected, affects) the surrounding environment and our lifestyle significantly. An earthquake can trigger many sudden changes in the environment which can Blank 3 Question 2 (would be classified, will classify, is classified, be classified) as primary and secondary. The subsidence and surface faulting Blank 4 Question 2 (is, was, were, are) the primary changes. The secondary effects are the displaced rocks, tsunami, ground cracks, liquefactions, landslides. These effects are known as earthquake environmental effects. The scales which use these effects of an earthquake as a parameter for assessment Blank 5 Question 2 (is known ,were known ,was known, are known) as Earthquake Intensity Scales. These scales Blank 6 Question 2 (quantified, quantification, quantity,quantify)  an earthquake based on the observed effects on the surroundings .The magnitude scales for earthquakes are logarithmic scales. The Richter scaleBlank 7 Question 2 (are based ,were based, had based, is based) on seismograph readings measuring Earth movement. In addition to the Richter scale, scientists also Blank 8 Question 2 (using ,will use, had used,use) a Moment Magnitude that measures the total energy of an earthquake, called the seismic moment. The seismic moment of an earthquake Blank 9 Question 2 (were determined, are determining, had determined, is determined) based on three factors. The first factor is the distance that rock slides along a fault surface after it breaks, called the fault slip. The second factor is the area of the fault surface that Blank 10 Question 2 (are, was, were, is)  actually broken by the earthquake. And the third factor is the measurement of how rigid the rocks are near the broken fault.

Tsunamis can result from ___________________.Select one:a.large volumes of water being displaced.b.an oceanic plate colliding into a continental platec.violent seafloor movement associated with earthquakes.d.an explosive volcanic eruption causing an earthquake in a continental plate.
