Plate tectonics: Practice Questions
5 multiple-choice questions marked as you go, and 3 written questions with worked solutions. All on Plate tectonics.
Which mechanism of plate movement involves the cooling and thickening of the lithosphere as it moves away from an ocean ridge, causing it to subside and 'slide' down the slope of the asthenosphere under gravity?
Evaluate the significance of slab pull in plate tectonic theory. Which statement best describes its role in crustal evolution?
In plate tectonic theory, ridge push is a mechanism of plate movement caused by:
Which landform is specifically associated with the subduction of an oceanic plate beneath a continental plate at a destructive margin?
Define a conservative plate margin and identify a characteristic tectonic process associated with it.
Write your answer out first, then check it against the worked solution.
Explain the physical mechanisms behind slab pull and ridge push as primary drivers of tectonic plate movement.
Write your answer out first, then check it against the worked solution.
Explain the process of lithospheric subduction and how it leads to the formation of deep-sea trenches and associated island arcs.
Write your answer out first, then check it against the worked solution.
