Resource summary

Question 1

Question
The asthenosphere is:
Answer
  • A layer of partially molten material within the upper part of the mantle
  • The section of the Earth's crust upon which contact is established between the partially molten mantle and the tectonic plates
  • An area within the mantle in which the lithospheric plates are sitting, made up of solid rock

Question 2

Question
The 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.
Answer
  • True
  • False

Question 3

Question
Geomorphology is specifically the: (can select more than one)
Answer
  • Study of landforms and their origin and evolution
  • Study of distribution and form of rocks and minerals inside the Earth's crust
  • Study of landforms and their distribution and form
  • Study of the origin and evolution of rocks and minerals inside the Earth's crust

Question 5

Question
The separation between the asthenosphere and the lithosphere is called the...
Answer
  • Mohorovic Discontinuity
  • Wegener Margin
  • Wegener Discontinuity
  • Mohorovic Margin

Question 6

Question
Alfred 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.
Answer
  • True
  • False

Question 7

Question
Tectonic Plate motion is widely believed to be caused by:
Answer
  • Convection currents in the mantle push the plates apart at diverging boundaries
  • Convection currents in the mantle carry the plates in directions from within the asthenosphere
  • Gravity pulls the plates towards the lowest point of altitude - the oceans - where they subduct or diverge and repeat the process
  • Convection currents in the mantle pull plates into subduction margins where displacement forces the other plates to move in the direction

Question 8

Question
Plates move at approximately ____ per year.
Answer
  • 1.5 - 7cm

Question 9

Question
Oceanic lithosphere (crust) is denser than continental lithosphere.
Answer
  • True
  • False

Question 10

Question
An oceanic plate is the plate underneath all the areas of the various oceans.
Answer
  • True
  • False

Question 11

Question
What plate boundary is shown in this image?
Image:
478c4713-bf2b-4a4a-8d86-146ac311ddde (image/png)
Answer
  • Diverging - Constructive
  • Converging - Destructive
  • Transformative - Conservative
  • Converging - Collision

Question 12

Question
Diverging plate boundaries can form:
Answer
  • Mid-ocean ridges as new crust is formed from solidified molten material
  • Mountain ranges as plates are pushed together, forcing crust upwards
  • Subduction, as one plate pushes the other into the mantle
  • Earthquakes as a single fault line releases the build-up of pressure along the plate

Question 13

Question
Converging plate boundaries between oceanic and continental crust can form...
Answer
  • Mid-ocean ridges as new crust is formed from solidified molten material
  • Mountain ranges as plates are pushed together, forcing crust upwards
  • Subduction, as one plate pushes the denser plate into the mantle
  • Earthquakes as a single fault line releases the build-up of pressure along the plate

Question 14

Question
A conservative margin between two plates can cause...
Answer
  • Mid-ocean ridges as new crust is formed from solidified molten material
  • Mountain ranges as plates are pushed together, forcing crust upwards
  • Subduction, as one plate pushes the denser plate into the mantle
  • Earthquakes as a single fault line releases the build-up of pressure along the plate

Question 15

Question
These landforms/activities are examples of destructive margins: (can select more than one)
Answer
  • Mount St Helens
