Erth 310 (GRPET) TEST WITH
COMPLETE SOLUTION
Chapter 2: What are Earth's layers defined by their chemical composition? -
ANSWER Crust, mantle, core
What are Earth's layers defined by their physical or mechanical properties? -
ANSWER Lithosphere, asthenosphere, mesosphere, outer core, inner core
The oceanic crust is less dense than the continental crust. - ANSWER False
The lithosphere is a brittle solid while the asthenosphere and mesosphere are
both ductile solids. - ANSWER True
The liquid outer core is responsible for Earth's magnetic field. - ANSWER
True
Chapter 3: A line in which two tectonic plates are moving away from one
another is called? - ANSWER Divergent boundary
A line in which two tectonic plates are sliding by one another laterally is
, called? - ANSWER Transform boundary
Where is crust created? - ANSWER Divergent boundary
Where can lithosphere be subducted? - ANSWER Convergent boundary
Deep earthquakes only happen in relation to a: - ANSWER Convergent
boundary
Chapter 4: What is a fault? - ANSWER A planar fracture along which rock on
either side has moved parallel to that fracture.
The focus of an earthquake is always found on the fault plane at depth. -
ANSWER True
The epicenter of an earthquake is always found on the fault plane at the
surface? - ANSWER False
What is the magnitude of an earthquake? - ANSWER A measurement that
represents all the energy released during a single earthquake.
