Geology 1001 Exam 1 LSU Questions
& Answers (Grade A+)
plate tectonics -
correct answer ✅continual motion, creation, and destruction of
the Earth's active surface; lithosphere and crust upper mantle
Continental Drift -
correct answer ✅The hypothesis that states that the continents
once formed a single landmass, broke up, and drifted to their
present locations
Alfred Wegener -
correct answer ✅A German meteorologist/ geologist who
proposed the theory of continental drift, but he did not have a goos
explanation for the mechanism to drive plate movement
mantle convection -
correct answer ✅a recurring current in the mantle that occurs
when hotter, less dense material rises, cools, and then sinks again.
This current is believed to be one of the driving forces behind
tectonic plate movement.
Arthur Holmes -
correct answer ✅proposed an explanation for cont. drift, radio
, Geology 1001 Exam 1 LSU Questions
& Answers (Grade A+)
activity in rocks could heat the mantle enough to cause convection
currents, causing contiental drift
Mid-Ocean Ridges -
correct answer ✅is an underwater mountain range, formed by
plate tectonics. This uplifting of the ocean floor occurs when
convection currents rise in the mantle beneath the oceanic crust
and create magma where two tectonic plates meet at a divergent
boundary.
Harry Hess -
correct answer ✅recognized how ocean bathymetry was shallow
in the middle of ocean Mt. ranges underwater
Paleomagnetism -
correct answer ✅The record of past changes in earth's magnetic
field, as recorded in in rocks and other materials. It's strong enough
to orient magnetism in certain materials, especially in iron rich
mineral magnetite, in the direction of the prevailing magnetic field.
Preserved in volcanic rocks, intrusive rocks, and some sedimentary
rocks
