Basics Ridge Mountain ridges refer to mountains which originate as a result of local folding and faulting. Generally, the slope of one side of the ridge is steep in contrast to the moderate slope on the other side (in case of Himalayas, the southern slope is steeper compared to the northern slope). In some cases, a ridge may have a symmetrical slope on both … [Read more...]

Fold Mountains Fold mountains are formed when sedimentary rock strata in geosynclines are subjected to compressive forces. They are the loftiest mountains, and they are generally concentrated along continental margins. Geosyncline: a large-scale depression in the earth's crust containing very thick deposits. E.g. Tethys geosyncline. ‘Fold’ in geology A fold … [Read more...]

Divergent Boundary In the Seafloor Spreading Theory, we have studied how divergent boundaries below the oceans are responsible for the spreading of the seafloor. In Plate Tectonics, we have learnt about the major and minor lithospheric plates and how these plates moved through the geological past. We have studied about convection currents in the mantle which are the … [Read more...]

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...]
