Question
This natural phenomenon causes an increase in earthquake frequency as a consequence of Mohr–Coulomb theory. For 10 points each:
[10h] Name this phenomenon that creates forebulges due to elastic lateral stress on the lithosphere. The Arun River’s contribution to this phenomenon has been hypothesized to affect Mount Everest’s height.
ANSWER: isostatic rebound [or post-glacial rebound; prompt on rebound; prompt on glacial isostasy or glacial isostatic adjustment]
[10m] The mechanism of isostatic rebound occurs due to pressure from this layer. This layer forms a low-velocity zone for seismic waves and causes seafloor spreading.
ANSWER: asthenosphere [prompt on mantle]
[10e] Measurements of this quantity account for gravitational variations from isostatic rebound. Global warming has caused a several-inch increase in this quantity over the past century, some of which is from melting glaciers.
ANSWER: mean sea level [or MSL]
