GEOLOGY 201 MIDTERM #1 EXAM QUESTIONS
WITH VERIFIED ANSWERS
Tectonic plates are made of:

Compared to passive margins, convergent margins are:
higher volcanic risks
Continental lithosphere is composed of:
felsic rock and ultra mafic rock (crust and upper mantle)
Passive continental margins:
include oceanic crust and continental crust on the same tectonic plate
The asthenosphere can be described as a layer of the Earth:
within the mantle comprised of ductile rock
The lithosphere can be described as a layer of the Earth:
within the crust and upper mantle comprised of rigid rock (brittle)
