The Most Likely Explanation for How Highly Fluidized Rock Flows

question 7

Multiple Choice

The most likely explanation for how highly fluidized rock flows occur is that ________________.

• A)the jostling of fragments in the flowing mass provides energy that propagates as trapped sound waves and supports the particles,thus fluidizing the mass (acoustic fluidization)
• B)water lubricates the material,allowing it to flow (hydro fluidization)
• C)steam lubricates the material,allowing it to flow (aqueous fluidization)
• D)the flowing mass rides on a cushion of compressed air (jetting)
• E)heat generated by friction melts material within the mass,allowing it to flow (thermal fluidization)

Member Method

A function defined within a class in object-oriented programming that can manipulate or access the object's data members.
