Resumo de Recurso

Questão 1

Questão
The asthenosphere is:
Responda
  • A layer of partially molten material within the upper part of the mantle

Responda
  • Mohorovic Discontinuity
  • Wegener Margin
  • Wegener Discontinuity
  • Mohorovic Margin

Questão 6

Questão
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.
Responda
  • True
  • False

Questão 7

Questão
Tectonic Plate motion is widely believed to be caused by:
Responda
  • 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

Questão 8

Questão
Plates move at approximately ____ per year.

  • True
  • False

Questão 10

Questão
An oceanic plate is the plate underneath all the areas of the various oceans.
Responda
  • True
  • False

Questão 11

Questão
What plate boundary is shown in this image?
Responda
  • Diverging - Constructive
  • Converging - Destructive
  • Transformative - Conservative
  • Converging - Collision

Questão 12

Questão
Diverging plate boundaries can form:
Responda
  • 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

Questão 13

Questão
Converging plate boundaries between oceanic and continental crust can form...
Responda
  • 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

Questão 14

Questão
A conservative margin between two plates can cause...
Responda
  • 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

Questão 15

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