Early Water on Mars Hindered Subduction-Driven Plate Tectonics
… evolution, but only Earth developed active plate tectonics. One of the main unresolved phenomena in planetary science is understanding why plate tectonics, particularly subduction-driven plate tectonics, failed to develop on Mars. Here, I investigate the possibility of subduction initiation …

The effect of changing topological constraints on poleward ocean heat transport induced by plate tectonics over the last 600 million years
The changing configurations of continents due to plate tectonics is thought to be responsible for some of the variation in climate over the last 600 Ma. Different topological constraints on the oceans may affect their ability to transport heat poleward and change the equilibrium pole-equator …

Tectonics of the West Iberia continental margin from seismic reflection data
… rifting is a fundamental component of the plate tectonic cycle. The West Iberia passive margin is a classic example of a nonvolcanic rifted margin. The West Iberia margin contains an enigmatic north-south ridge of serpentinized peridotite located within the ocean-continent transition. …

Investigating introductory science students’ knowledge of multiple representations using technology
… students’ spatial ability and knowledge of plate tectonics. These attributes were measured by a set of computer-based spatial ability assessments and a geology version of the VRA, respectively. A multiple linear regression analysis suggests there was no meaningful relationship between …

The Influence of Curvature on Mantle Convection featuring a Temperature-dependent Viscosity
… of a magnetic field is associated with plate-tectonics because efficient heat extraction is required at the core-mantle boundary. However, the planet Mercury, which does not have plate-tectonics, features a magnetic field. The work presented concludes by investigating the evolution of …

Visualizing and Understanding Tectonism and Volcanism on Earth and Other Terrestrial Bodies
… teaching, assessing, modeling, and understanding tectonics on Earth and other celestial bodies. Tectonics is the study of planetary lithospheres and includes impact, plate, plume, cryo- and gravitational mechanisms. This dissertation is concerned with plate tectonics and plate/mantle plume …

INFERRED RHEOLOGY AND UPPER MANTLE CONDITIONS OF WESTERN NEVADA AND SOUTHERN CALIFORNIA-NORTHWEST MEXICO
… as mantle convection, the earthquake cycle, and plate tectonics. This study uses tectonic (postseismic) and non-tectonic (lake unloading) events that have induced differential stress changes within the crust and mantle, which in turn, create surface deformation. The viscoelastic relaxation is …

Antarctica: A Geography of the Sacred
… Through a coincidence of geology, glaciology and plate tectonics, the topography of Antarctica echoes these designs almost perfectly - the coastal regions and southern ocean corresponding to the picturesque outer ring or structure, the minimalist ice shelves and Polar Plateau corresponding the …

Seismic and numerical constraints on the formation and evolution of oceanic lithosphere
… the lithosphere. The strength of lithospheric plates relative to the underlying mantle enables the surface plate motions and plate boundary processes that characterize plate tectonics on Earth. Surprisingly, we have a relatively poor understanding of the physical mechanisms that make the …

Dynamic processes at submarine plate boundaries
The theory of plate tectonics provides a simplified yet powerful framework to describe the motion of lithospheric plates and the deformation that takes place at their boundaries. Although plate boundaries represent a small fraction of the earth’s surface, the localisation of stresses, resulting …

The tectonic evolution of Antarctica
