Which plays a dominant role in the movement of the earth s crust, horizontal or ascending?

The complex crustal movement can be divided into two basic forms: horizontal motion and lifting motion according to its nature and direction. Horizontal motion refers to the movement of the rock layers that make up the earth's crust in a direction roughly parallel to the earth's surface. It is often manifested as the horizontal movement and bending deformation of crustal rock strata.

Upward and downward movement refers to the upward or downward movement of the rock layers that make up the earth's crust in a perpendicular direction to the earth's surface, also known as vertical movement. It often manifests as a massive bulge or depression. The horizontal movement and the up-and-down movement of the earth's crust are caused by internal dynamic geological processes, which are interrelated, mutually influencing, and closely related to each other, and are not carried out in isolation.

For example, when the horizontal movement of the crust makes the rock layer bent and deformed, not only the rock layer is shortened in the horizontal direction, but also the uplift part rises relatively and the depression part declines relatively, indicating that the horizontal movement plays a leading role at this time, and the vertical motion is derived. At the same time, when the crustal uplift or settlement caused by the lifting movement of the rock formation, the horizontal displacement of the local rock formation can also be caused, and the lifting movement plays a leading role at this time.

Usually in areas where horizontal movement is dominant, it often results in huge folded mountain systems. For example, China's Himalayas, Kunlun Mountains, Qilian Mountains, etc., as well as many mountain ranges in the world, are formed by extrusion and folding. In areas dominated by lifting movements, uplifts and subsidences cause changes in elevation and sea and land changes.

Modern crustal movements, such as Scandinavia, Northern Europe, are now rising at a rate of 2 cm a year, and the Netherlands is sinking at a rate of 3 mm a year. The Himalayas were uplifted 30 million years ago and are still rising today.

However, from the whole history of the development of the earth's crust and a large amount of data, the main manifestation of the earth's crustal movement on a global scale is the dominant factor in the relative motion in the horizontal direction. The Atlantic Ocean is the result of the horizontal movement of the earth's crust, and it is still expanding. Lifting motion is a secondary factor or derived.

The basic concept of geomechanics founded by Mr. Li Siguang, a famous geologist in China, is famous for its theoretical basis on the theory of horizontal motion of the earth's crust.

In the movement of the earth's crust, horizontal motion and lifting motion are the two manifestations of the movement of the earth's crust, and there is no distinction between primary and secondary.

If we do not understand the form of crustal movement, the general history of crustal movement, and the law of crustal movement, we cannot see the formation and evolution process and structural relationship of today's sea and land structure.

If you don't know the absurdity of modern geoscience theory, and its questions and answers are not realistic, you just talk exaggerated from the level of thinking, and persuade you to stop, so as not to mislead students and followers of the theory.

The movement of the earth's crust is complex and diverse, and according to the nature and direction of the earth's crustal movement, it can be divided into two types: horizontal movement and lifting movement.

Horizontal movement refers to the movement of the rock layers that make up the earth's crust in the direction parallel to the earth's surface, which causes the rock layers to undergo horizontal displacement and bending deformation. A large number of data prove that the main manifestation of the movement of the earth's crust is the continuous horizontal movement of its parts.

Upward and downward movement refers to the movement of the rock layers that make up the earth's crust in the direction perpendicular to the earth's surface, that is, the upward or descending movement. It causes the rock formation to appear as a bulge or depression, which causes the ups and downs of the terrain and the changes of land and sea.

The speed at which the earth's crust moves is uneven. ** With its sudden, instantaneous, and violent special form of movement, people can directly feel the occurrence of crustal movement; The general, frequent crustal movement, because of its very slow progress, is not easy to be directly detected by people, but it controls the vicissitudes of the earth's surface, affects the occurrence of various geological processes, and shapes new tectonic forms.

Geological processes can be divided into internal forces and external forces according to their energy. The energy of the internal force tumbling comes from the earth itself, mainly the heat energy produced by the decay of radioactive elements. The energy of the external force comes from the outside of the earth, mainly the solar energy, followed by the gravitational energy.

Answer] :d term d, the pedestal terraces are mostly distributed in the middle and lower reaches of the river, which are formed when the valley widens and the wheel pins are piled up, and the later downcut depth exceeds that of the alluvial lap and swims into the bedrock. The pedestal terraces are associated with the uplift of the crust; Item A, Oxbow Lake is a landform formed by silting up the original curved river channel when the river bends very badly, once the bend is straightened; b, alluvial fan is a fan-shaped accumulation or cone-shaped accumulation formed by the intermountain torrent carrying a large amount of detrital material at the mouth of the ravine due to the sudden change of slope drop; C, landslide terrace refers to a landslide body on both sides of the river valley or in the foothill area that is very similar to a terrace.

The material of the landslide terraces comes from the rocky terraces on the valley slopes and is formed by intermittent crustal movements and river downcutting.

The vertical movement of the earth's crust, also known as the lifting movement and land-building movement, makes the rock formation appear as an uplift in the ascending zone and a descent in the adjacent descending zone.

The earth's crust rises to form plateaus, fault mountains, and crustal subsidence forms depressions, basins, and plains.

Summary. East African Plateau: Vertical Zone.

The altitude of this area is more than 3,000 meters, and due to the high terrain, the temperature and precipitation conditions here have changed, and the climate is warm, and the tropical rainforest climate cannot be formed. In summer, under the influence of the warm and humid southeast monsoon from the Indian Ocean that passes over the warm current, there is more precipitation, forming a wet season. In winter, the order is accepted.

1. Dry monsoon control, less precipitation, and vigorous ground evaporation, forming a dry season.

What are the plateaus formed by the vertical movement of the earth's crust.

Loess plateau. Can you ask us a little more about the causes of the East African plateau?

Plateau genesis is not climatic cause.

This is where the land mass separates, i.e. in eastern Africa, which is exactly in the zone of strong upwelling of mantle material. Under the action of upwelling, the East African crust is uplifted to form plateaus.

Answering ideas modeling:

1. The formation process of topography and landform

Environmental characteristics of a landscape at different moments – marine or terrestrial environment; internal or external force environment, etc.

Matter – magma, rock formations, sediments, etc.

The moving jujube-type form of the earth's crust – uplift or depression.

Geological action forms - internal forces (cooling, solidification, metamorphism, etc.), external forces (weathering, erosion, transportation, accumulation, consolidation), etc.

2. The sequence of occurrence of geological processes:

Erosion is preceded by uplifting, and sedimentation is preceded by sinking.

Sedimentary rocks are stratified, and the higher up you go, the younger the rock layers become. The intrusive precedes the intruder.

Generally, it is folded first and then faulted.
