Convergent Boundary Along a convergent boundary two lithospheric plates collide against each other. When one of the plates is an oceanic plate, it gets embedded in the softer asthenosphere of the continental plate, and as a result, trenches are formed at the zone of subduction. Convergent Boundary In convergence there are subtypes namely: Collision of … [Read more...]

Interaction of Tectonic Plates Major geomorphological features such as fold and block mountains, mid-oceanic ridges, trenches, volcanism, earthquakes etc. are a direct consequence of the interaction between various Tectonic Plates (lithospheric plates). There are three ways in which the plates interact with each other. Types of Tectonic Plate Boundaries (Jose F. … [Read more...]

Plate Tectonics It was from the continental drift theory, convection current theory and the theory of seafloor spreading, the theory of Plate Tectonics was formulated. In 1967, McKenzie and Parker suggested the theory of plate tectonics. Morgan later outlined the theory in 1968. According to the theory of plate tectonics, the earth’s lithosphere is broken into … [Read more...]

To understand the concept of Seafloor Spreading, we must first understand some basic concepts that form the cornerstones for the concept of Seafloor Spreading. These cornerstones are Convectional Current Theory and Paleomagnetism. Convection Current Theory Convection Current Theory is the soul of Seafloor Spreading Theory. Arthur Holmes in 1930s discussed the … [Read more...]
