The geology of Vietnam is divided into five structural blocks : Northeast (NE), Northwest (NW), Truongson, Kon Tum and Nambo.The NE block is a part of the South China plate, in which strata and igneous rocks have been found dating from the Early Paleozoic to the Quaternary.
Erosion and changes in the form of river banks may be measured by inserting metal rods into the bank and marking the position of the bank surface along the rods at different times. [23] Thermal erosion is the result of melting and weakening permafrost due to moving water. [24] It can occur both along rivers and at the coast.

Bank erosion is the wearing away of the banks of a stream or river. This is distinguished from changes on the bed of the watercourse, which is referred to as scour. Erosion and changes in the form of river banks may be measured by inserting metal rods into the bank and marking the position of the bank surface along the rods at different times. [17]
The structures of The Complex of Huế Monuments are carefully placed within the natural setting of the site and aligned with the concept of oriential geomancy and Five elements [3] which including Five Cardinal Points (center, west, east, north, south), the Five Elements (earth, metal, wood, water, fire), and the Five Colors (yellow, white ...
Earth is rounded into an ellipsoid with a circumference of about 40,000 km. It is the densest planet in the Solar System. Of the four rocky planets, it is the largest and most massive. Earth is about eight light-minutes away from the Sun and orbits it, taking a year (about 365.25 days) to complete one revolution.
The geographic cycle, or cycle of erosion, is an idealized model that explains the development of relief in landscapes. [1] The model starts with the erosion that follows uplift of land above a base level and ends, if conditions allow, in the formation of a peneplain . [ 1 ]
