the study area, paykola anticline, is located in the southwestern part of kermanshah province. the aim of this research is to evaluate the geomorphological indexes of active tectonics in paykola anticline as well as to study the effect of tectonic in the form and direction of geomorphological landforms. to achieve the aim of study, the lithological and tectonic characteristics of study area wer...

Geomorphic parameters are very helpful as they can quickly explain the concerned area, which is going through a tectonic adjustment. For this purpose, four indices were applied to examine active tectonics in Quetta-Ziarat region. These include: sub-basins asymmetry (Af), transverse topography (T-Factor), hypsometric integral (HI) and stream-length gradient (SL). The calculation of three denoted...

Abstract. Using digital educational resources (DERs) in science education is an effective way of promoting students' content knowledge complex natural processes. This work presents the usage resource CreativeLab_Sci&Math | Plate Tectonics, designed for exploring PhET™ Tectonics simulator, context pre-service teachers (PSTs) Portugal. The performance PSTs was analysed based on five tasks...

The rapid development of digital technology has an impact on the ease processing mass forms and appearance buildings in architecture. This significantly influenced tectonics as important part Tectonics is like finding a new window view from same existence. situation demands explanation position role contemporary architectural works. very to rediscover nature art construction face technology. pa...

Contrary to predictions of the tidal torque model, length of day (LOD) decreases over a series of fluctuations since 1960s at least. The so far deepest LOD depression of 1997 – 2010 corresponds to the most prominent rises of total seismic activity and global mean temperatures. A conspicuously flat interval of the LOD curve uniformly at or slightly below –0.1 ms level in 2001 – 2005 roughly coin...

[1] We argue that by fracturing rock, not by raising it relative to base level, tectonics plays its most important role in causing rapid incision of valleys and rapid erosion of hillslopes. Tectonic deformation riddles the upper crust with fractures, which not only provide avenues for water flow and thus promote weathering and further disintegration of rock but also fragment bedrock into debris...

SINCE THE l6TH CENTURY, CARTOGRAPHERS HAVE NOTICED THE jigsaw-puzzle fit of the continental edges. Since the 19th century, geologists have known that some fossil plants and animals are extraordinarily similar across the globe, and some sequences of rock formations in distant continents are also strikingly alike. At the turn of the 20th century, Austrian geologist Eduard Suess proposed the theor...

The wealth of new data, mostly from the ocean bottom, that precipitated the acceptance of plate tectonics during the 1960’s simultaneously also opened the door for the first time in more than 200 years to a technically credible defense of the Genesis Flood. From the mid-1700’s through the days of Hutton, Lyell, and Darwin to the 1960’s, it overwhelmed the human mind to imagine a mechanism that ...

Contained fluids heated from below spontaneously organize into convection cells when sufficiently far from conductive equilibrium. Fluids can also be organized by surface tension and other forces at the top. Plate tectonics was once regarded as passive motion of plates on top of mantle convection cells but it now appears that continents and plate tectonics organize the flow in the mantle. The f...

abstract alluvial fans are the most striking phenomena o fluvial geomorphology . these forms are found in frount of mountains and pediments of arid and semiarid zones . alluvial fans are affected by climate changes and tectonics . occurring of tectonic events lead to reaction of alluvial fans . some of these reactions appear on dissection of alluvial fans and displacement of depocenters on allu...
