16 common landforms in high school geography

16 The common landforms of high school geography are as follows:

1, karst landform

It is the general name of the surface and underground forms formed after soluble rocks are dissolved by water, also known as karst landform. Karst landform has dissolution force and mechanical erosion processes such as flowing water erosion, undercurrent and collapse.

2. Danxia landform

It is the general name of Fangshan, Qifeng, cliff, karst cave, stone pillar and other special landforms composed of extremely thick red sandstone and conglomerate. From Jurassic to Tertiary, it was formed by the long-term interaction of flowing water, gravity and weathering and erosion external forces.

3. Aeolian landform

It is a terrain formed by surface wind accumulation. It is mainly influenced by ancient river alluvial deposits, modern river alluvial deposits, alluvial-lacustrine deposits, diluvial-alluvial deposits, ice water deposits and bedrock weathering residues.

4. Loess landform

It is a soil-like deposit formed in Quaternary. Due to the erosion of running water, the surface is broken and fragmented.

Step 5 collapse

Collapse is a common landform, which can be divided into different forms of landslide, bank collapse and loose body.

6. Glacial landform

Surface morphology formed by glacial erosion and accumulation. 1 1% of the earth's land surface is covered by modern glaciers, which are mainly distributed in polar regions, middle and low latitudes, mountains and plateaus.

7. Ya Dan landform

It is a landscape in the inland desert of China, which consists of a series of intermittent long mounds and concave grooves.

8. Gravity landform

The surface morphology formed by the displacement of rock mass or soil mass on the slope under its own gravity. Because the materials moved by gravity on the slope are mostly blocks, this movement is also called block movement.

9. Coastal topography

Coastal landform is a multi-factor landform, including tectonic movement, seawater dynamics, biological action and climate factors.

10, river landform

River geomorphology is the most frequent and active geomorphological action on the earth's surface, which runs through the whole process of river geomorphology.

Landslide is a transitional landform between gravity landform and flowing water landform.

12, lake landform

Lake landform is caused by lake water action, including lake wave erosion, transportation and accumulation.

13, volcanic landform

Volcanic landform is a mountain form formed by magma ejection and accumulation in the crust.

14, Plateau

The plateau was formed in the long-term and sustained large-scale crustal uplift movement of Qinghai-Tibet Plateau, Inner Mongolia Plateau, Loess Plateau and Yunnan-Guizhou Plateau. The plateau is generally above 1000 meters above sea level, with vast territory, open terrain and obvious steep slopes around.

15, underground river

Underground river is a landform, also known as "underground river" and "undercurrent". Due to karstification, karst caves and underground passages are formed in large limestone areas, and surface rivers often pass through the karst caves and dive underground to form underground rivers.

16, desert, dune landform

Desert and dune landforms are typical landforms formed by wind accumulation. They are mainly composed of crescent dunes, dune chains, sand ridges and sandy land.
