Which teacher can describe in detail the movement of the geographical crust and the causes of the ge

The movement of the earth's crust is a tectonic movement caused by internal forces to change the structure of the earth's crust and displace the material inside the earth's crust. The movement of the earth's crust with respect to the earth's surface. The movement of the earth's crust, as it is commonly called, actually refers to the movement of the lithosphere relative to the Earth's interior below the asthenosphere.

Below the lithosphere is a layer of softer strata that are prone to plastic deformation, which is different from the crusty surface, which is the asthenosphere. The crusty surface above the asthenosphere includes the crust and the top of the upper mantle. The Earth's crust is tightly bonded to the top of the mantle to form a lithosphere, which can move above the asthenosphere.

Geographical formations are actually called geological formations. The high mountains and lowlands formed by the movement of the earth's crust are called tectonic landforms.

The movement of the earth's crust can be divided into horizontal motion and vertical motion according to the direction of motion. 1. Horizontal motion refers to the movement of the rock layers that make up the earth's crust in the direction of the earth's surface along the parallel crustal movement diagram. Also known as orogeny or folding.

This movement can often form huge folded mountain systems, as well as giant depressions, island arcs, trenches, etc. 2. Vertical movement, also known as lifting movement and land-building movement, makes the rock layer appear as a uplift and the decline of adjacent areas, which can form plateaus, fault-block mountains and depressions, basins and plains, and can also cause sea transgression and sea retreat, so that the sea and land change. Crustal movement controls the distribution of sea and land on the earth's surface, affects the occurrence and development of various geological processes, forms various tectonic forms, and changes the original state of rock formations, so some people also call crustal movement tectonic movement.

The Earth's interior is liquid stone, constantly moving, and has been in space for 4.6 billion years made up of rubble.

The characteristics of crustal tectonic movement and its manifestations in lithofacies, construction and stratigraphic contact relationships are as follows:

1) The characteristics of the tectonic movement of the earth's crust are matched.

Tectonic movements are mainly mechanical movements of the earth's crust caused by the internal dynamics of the earth. Tectonic motion has the characteristics of universality, eternity, directionality, heterogeneity, amplitude and scale differences.

and 2) the relationship between tectonic movement and lithofacies, construction and stratigraphic contact.

Lithofacies. The lithofacies of sedimentary rocks are usually divided into three categories: marine facies, continental facies, and transitional facies. When the crust rises, the lithofacies changes from marine to terrestrial, and the sediment grain size increases and the thickness decreases, forming a retreat sequence. Conversely, the sinking of the earth's crust forms a transgression sequence.

Sedimentary construction. Sedimentary construction is a combination of strata or lithofacies that have a symbiotic relationship with each other, or a combination of sediments with roughly the same lithology. The basic construction types include trough type construction, platform type construction, and transitional construction.

Stratigraphic contact relationships.

It is mainly divided into three categories: integration, pseudointegration and unconformity, which can clearly reflect a certain characteristic of tectonic movement.

a.Conformity. It refers to the fact that the occurrence of adjacent new and old strata is consistent and parallel to each other, and the era is continuous.

b.Disconformity. It refers to the parallel occurrence of two adjacent strata but the age is not continuous.

c.Non-integration. It refers to the fact that the occurrence of the upper and lower strata is neither consistent nor continuous, and there is a lack of strata in between.

The basic form of crustal movement is the locust ant

The basic forms of crustal motion are horizontal motion and vertical motion. Horizontal motion: Horizontal motion refers to the movement of crustal materials roughly along the tangent direction of the geoidic spherical surface, which is often manifested as the horizontal movement of crustal rock layers, forming huge folds and fault structures, causing continental drift and seafloor expansion.

Vertical motion: refers to the movement of crustal materials roughly along the normal direction of the geoidic spherical surface, which is often manifested as large-scale uplift and depression, and causes changes in the height of the terrain and the advance and retreat of seawater.

The range caused by the macro and vertical movement of the earth's crust is larger than that of the plate movement, which mainly refers to the movement of rock formations, and the movement of the earth's crust also includes the movement of magma; Crustal movement is one of the manifestations of internal force in geological action, and geological structure is the result of crustal movement, which deforms and displaces rock layers to form geological structures, such as folds and faults.

1. Plate motion refers to the relative motion of one plate on the earth's surface against another.

In 1968, the French geologist Lepishun divided the earth's rock layers into six large plates, which float in the fluid mantle.

Above the asthenosphere, with the movement of the asthenosphere, each or a wide plate will also undergo corresponding horizontal movements.

2. The movement of the earth's crust is the mechanical movement of the earth's materials caused by the internal causes of the earth.

Crustal movement is a tectonic movement caused by internal forces to change the structure of the earth's crust and displace the material inside the earth's crust, which can cause the evolution of the lithosphere, promote the rise and extinction of the continental and ocean floors, and form trenches and mountains, and also lead to the occurrence of ** and volcanic eruptions.

Wait. 3. Geological structure is the trace left by the movement of the earth's crust.

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.

Crustal movement is the mechanical movement of the earth's materials caused by the internal causes of the earth. Crustal movement is a tectonic movement caused by internal forces to change the structure of the earth's crust and displace the material inside the crust, which can cause the evolution of the lithosphere, promote the growth and extinction of the continental and ocean floors, and form trenches and mountains, and may also lead to the occurrence of natural disasters such as volcanic eruptions.

The intuitive manifestations of crustal movement include **, volcano, (caused by the collision and movement of continental plates).

1. The range caused by the movement of the whole crust is greater than that of the plate movement. Plate movement mainly refers to the movement of rock formations, while crustal movement also includes magma movement.

Crustal movement is the mechanical movement of the earth's materials caused by the internal causes of the earth. Crustal movement is a tectonic movement caused by internal forces to change the structure of the earth's crust and displace the material in the earth's crust, which can cause the evolution of the lithosphere and promote the growth and extinction of the continental and ocean floors. and the formation of trenches and mountains; At the same time, it also leads to the occurrence of **, volcanic eruptions, etc.

The absolute plate velocity model: refers to the relative motion of one plate on the earth's surface against another. In 1968, the French geologist Le Pishun divided the earth's rock layers into six large plates, all of which float above the fluid mantle asthenosphere.

As the asthenosphere moves, the plates also move horizontally accordingly.
