1The asthenosphere is:
- AA layer of partially molten material within the upper part of the mantle
- BThe section of the Earth's crust upon which contact is established between the partially molten mantle and the tectonic plates
- CAn area within the mantle in which the lithospheric plates are sitting, made up of solid rock
2The majority of landform features associated with the Earth's internal forces are the result of large, spectacular movements constantly being repeated every few thousand years.
- ATrue
- BFalse
3Geomorphology is specifically the: (can select more than one)
- AStudy of landforms and their origin and evolution
- BStudy of distribution and form of rocks and minerals inside the Earth's crust
- CStudy of landforms and their distribution and form
- DStudy of the origin and evolution of rocks and minerals inside the Earth's crust

5The separation between the asthenosphere and the lithosphere is called the...
- AMohorovic Discontinuity
- BWegener Margin
- CWegener Discontinuity
- DMohorovic Margin
6Alfred Wegener began his theory of Continental Drift in 1915, but lacked scientific interest because it could not provide substantial evidence for a medium to which continents could move.
- ATrue
- BFalse
7Tectonic Plate motion is widely believed to be caused by:
- AConvection currents in the mantle push the plates apart at diverging boundaries
- BConvection currents in the mantle carry the plates in directions from within the asthenosphere
- CGravity pulls the plates towards the lowest point of altitude - the oceans - where they subduct or diverge and repeat the process
- DConvection currents in the mantle pull plates into subduction margins where displacement forces the other plates to move in the direction
8Plates move at approximately ____ per year.
- A1.5 - 7cm
- B15 - 70cm
- C1.5 - 7m
- D15 - 70m
9Oceanic lithosphere (crust) is denser than continental lithosphere.
- ATrue
- BFalse
10An oceanic plate is the plate underneath all the areas of the various oceans.
- ATrue
- BFalse
11What plate boundary is shown in this image?
- ADiverging - Constructive
- BConverging - Destructive
- CTransformative - Conservative
- DConverging - Collision
12Diverging plate boundaries can form:
- AMid-ocean ridges as new crust is formed from solidified molten material
- BMountain ranges as plates are pushed together, forcing crust upwards
- CSubduction, as one plate pushes the other into the mantle
- DEarthquakes as a single fault line releases the build-up of pressure along the plate
13Converging plate boundaries between oceanic and continental crust can form...
- AMid-ocean ridges as new crust is formed from solidified molten material
- BMountain ranges as plates are pushed together, forcing crust upwards
- CSubduction, as one plate pushes the denser plate into the mantle
- DEarthquakes as a single fault line releases the build-up of pressure along the plate
14A conservative margin between two plates can cause...
- AMid-ocean ridges as new crust is formed from solidified molten material
- BMountain ranges as plates are pushed together, forcing crust upwards
- CSubduction, as one plate pushes the denser plate into the mantle
- DEarthquakes as a single fault line releases the build-up of pressure along the plate
15These landforms/activities are examples of destructive margins: (can select more than one)
