Analysis of the genesis of typical landscape landforms, and the genesis of various landforms

The landform landscape includes karst landform, Danxia landform, Yadan landform, glacier landform, loess landform, etc.

1. Karst landform

A general term for the surface and underground forms formed by the dissolution of soluble rocks by water with the dissolution power of karst landforms. Also known as karst landforms. The action of water on soluble rocks is collectively referred to as karst.

It is mainly based on dissolution, but also includes the erosion of flowing water, latent erosion, and mechanical erosion processes such as collapse.

2. Danxia landform

It belongs to the red-bed landform, which is a horizontal tectonic landform. It refers to the red sand row of coarse rock after long-term weathering and stripping and flowing water erosion, forming isolated peaks and steep strange rocks, is the huge red sand, conglomerate layer along the development of various Danxia peaks along the vertical joints of the general name.

3. Yadan landform

The appearance of the earth endowed by hundreds of millions of years of geological changes has been continuously eroded by natural water flow and wind day and night, shaping a variety of strange forms in many places, forming a variety of special landforms, such as: river valley landform, karst landform, moraine landform, wind erosion landform and so on.

4. Glacial landforms

Glaciers are quasi-plastic, and the movement of glaciers includes two parts: internal movement and bottom sliding, which is the dynamic rolling of erosion, transport, accumulation and shaping of various glacial landforms. However, it is not the only driving force that shapes the glacial landform, but the combined action with various stresses such as frost, snow erosion, avalanche, and flowing water to form the landform landscape of the glacial area.

5. Loess landform

Loess morphology is a topography developed in loess layers (including loess-like soils). Loess is a continental pale yellow silty soil-like accumulation formed in the Quaternary period.

The causes of landform are divided into internal and external forces, and the geomorphology is the joint result of internal and external forces.

The energy of internal forces** comes from the Earth's interior. It is a variety of tectonic movements, including folds, faults, volcanoes, **.

The energy of the external force comes from solar radiation. Including various weathering, erosion, handling, accumulation and other effects.

Internal and external geological processes are related to each other and work together. The internal forces complicate the composition and structure of the earth's interior and crust, forming the ups and downs of the earth's surface. External forces act on the undulations of the earth's surface, both acting on the surface at the same time.

1. Tectonic movement.

2 climatic factors.

3 lithologies 4 organisms.

5. Human activities.

There are both internal and external forces. Internal forces such as plate movement, magma movement, plate extrusion, collision, fracture to form folds and other terrain, external forces include weathering, erosion of flowing water, sedimentation and other effects and organisms. These factors work together to form the landscape.

First there are internal forces that make the earth uneven, and then there are external forces.

Landform type: The abbreviation of the geomorphological type of landform.
