  • Q6

    Determine whether the two statements are true:

    Statement 1:Exogenicprocesses include geological phenomena and processes that

                          originate externally tothe Earth’s surface.

    Statement 2: They aregenetically related to the atmosphere, hydrosphere, and biosphere,

                          and therefore, toprocesses of weathering, erosion, transportation, deposition,

                          denudation, etc.

    Both statements are true.

    Both statements are untrue.

    The first statement is true and the second is otherwise

    The first statement is untrue and the second is otherwise.

  • Q7

    Which of the following sets of conditions best trigger mass wasting?

    gravity, slope angle, and presence of water

    gravity, slope angle, and weak materials and structure

    gravity, slope angle, presence of water and weak materials, and structure

    gravity, slope angle, presence of water, presence of clay, weak materials, and structure

  • Q8

    How will you classify the mass wasting process shown in the picture below?

    Question Image

    Slope Failure

    Sediment flow

    Granular flow

    Fluvial flow

  • Q9

    Determine whether the two statements are true:

    Statement1: Higher slope means higher susceptibility to mass wasting and higher rate of  

                           erosion.

    Statement2: On a gentle slope however, water tend to stay longer that leads to higher rate

                           of weathering.

    Both statements are true.

    Both statements are untrue.

    The first statement is true and the second is otherwise.

    The first statement is untrue and the second is otherwise.

  • Q10

    Why is the movement of glacial erosion hard to see?

    Because glaciers move very slowly

    Because glaciers are huge

    Because glacial erosion is usually subtle

    Because light from glaciers refracts too much

  • Q11

    Which of the following is TRUE about rock stress?

    Forces applied to a rock that cause it to break and into fragment are not considered as stresses to a rock.

    Forces that cause stress can either move towards each other, away from each other, or anti-parallel from each other.

    Forces that cause stress on a rock are not always externally applied.

    Forces that cause rock stress do not occur naturally.

  • Q12

    Why does water have the power to split rocks? It is because when it freezes, it:

    contracts

    expands

    evaporates

    condensates

  • Q13

    Which statement is correct for the deformation of rocks to occur?

    The rock material must have the ability to deform under pressure and heat

    The lower the temperature of the rock, the more elastic it becomes

    Pressure must exceed the internal strength of the rock

    Deformation must be applied abruptly

  • Q14

    Which of the following rock stresses cause forces to move towards each other?

    tension

    compression

    shearing

    normal force

  • Q15

    When an earthquake occurs, rocks move anti-parallel to each other, causing rocks to slip and cleave. Which type of rock stress exemplifies this situation?

    tension

    compression

    shearing

    normal force
