The depth of deep-ocean trenches is closely related to age: the younger the subducting plate, the deeper the trench.
Indicate whether this statement is true or false.
Q. 2 - Most mountain ranges formed through cooling of the Earth's crust, which resulted in wrinkling as it contracted.
Indicate whether this statement is true or false.
Q. 3 - Why would geologic mapping be difficult in an area dominated by accreted terranes?
A) The geology is so similar that it would be difficult to determine terrane boundaries
B) Each terrane is geologically distinct, but also highly deformed
C) Isostatic rebound would result in gravitational collapse to make them indistinct
D) Terranes are very old and terribly eroded
Q. 4 - Passive continental margins will have a well-developed forearc and back-arc basin system.
Indicate whether this statement is true or false.
Q. 5 - Because the Indian subcontinent is still colliding with the Eurasian Plate, the Himalayas are still actively forming.
Indicate whether this statement is true or false.
Q. 6 - Fault-block mountains form only along divergent plate boundaries.
Indicate whether this statement is true or false.
Q. 7 - How would the angle of subduction of a tectonic plate influence the location of a volcanic arc?
A) The steeper the angle, the closer the arc would form to the trench
B) The shallower the angle, the closer the arc would form to the trench
C) The steeper the angle, the further the arc would form to the trench
D) The angle of subduction doesn't affect the location of the volcanic arc
Q. 8 - Forearc basins will consist of thick sequences of highly deformed sedimentary rocks.
Indicate whether this statement is true or false.
