What is conservative margin?
Regional SpecificsA conservative (passive or transform as it is also known) plate margin involves two tectonic plates sliding past each other. The plates do not pass each other smoothly. Friction causes them to get stuck. Over time pressure builds up until the friction is overcome which results in the plates slipping. What does conservative margin mean?
Who first presented the periglacial cycle of erosion?
Regional SpecificsIn 1950 L.C Peltier put forward the concept of a periglacial cycle of erosion. Who propounded glacial cycle of erosion? William Morris Davis However the immediate influences of William Morris Davis, the creator of the cycle of erosion model, were 19th century American explorers. Who was the first to give the idea of cycle of
Why is sequence stratigraphy important?
Regional SpecificsSequence stratigraphy can be used to develop more accurate surfaces for mapping and correlating facies; predict reservoir, source and sealing facies; identify stratigraphic traps; and project reservoir trends into areas with limited data. Why principles of stratigraphy is important? stratigraphy, scientific discipline concerned with the description of rock successions and their interpretation in terms of
What is the density of the mantle?
Regional Specifics3“>4.5 g/cm34.5 g/cm3, and temperatures in the range of 1000-1500 oC. The uppermost layer of the mantle is more rigid, while the deeper regions are fluid, and it is the motion of fluid materials in the mantle that is responsible for plate tectonics (see section 4.3). What is the average density of the lower mantle?
What is a reverse earthquake?
Regional SpecificsIf the rock mass above an inclined fault moves down, the fault is termed normal, whereas if the rock above the fault moves up, the fault is termed reverse. What is the meaning of reverse in earthquake? How does a reverse fault move? In a reverse fault, the block above the fault moves up relative
Why are oceanic plates denser than Continental?
Regional SpecificsWhy is the oceanic crust more dense? Oceanic crust is denser because it generally melts to a higher fraction than continental crust. When rocks melt to 20–30% like they do at mid-ocean ridges, the result is more dense than when rocks melt to form continental plates, which is typically 1–5%. Why is continental crust less
