What happens if a land plate collides with a land plate

In areas where two continental plates collide and squeeze, huge mountain ranges are often formed, such as the Himalayas, which are formed by the collision of the Eurasian plate and the Indian plate.

The contact zone between the plates is volcanic, **, geothermal activity zone.

The edge of the city is creative haha.

Oceanic plates collide with continental plates, forming ocean trenches.

Continental plates collide with continental plates, forming mountain ranges.

When the oceanic plate collides with the continental plate, the oceanic plate subducts below the continental plate due to its high density and low position, where it often forms a trench and becomes the deepest place in the ocean. The continental plate is squeezed into an arch and uplifted into island arcs and coastal mountains. The deep trenches and island arc chains in the western Pacific Ocean were formed by the collision of the Pacific plate and the Eurasian plate.

Where two continental plates collide, huge mountain ranges often form. The Himalayas were created by the collision of the Indian plate with the Eurasian plate.

Collision of oceanic and continental plates: the edge of the continental plate is squeezed and uplifted into island arcs or coastal mountains (examples: island arc chain in the western Pacific Ocean, coastal mountains in the western Americas); The oceanic plate subducts beneath the continental plate to form a trench. (Example: Mariana Trench).

Continental plates collide with continental plates: huge folded mountain systems are formed. (Examples: Himalayas, Alps).

The phenomenon of two plates of the same type (both continental crustal plate or ocean crustal plate) meeting and moving relative to each other is a plate collision. Since the lithospheric density of the same type of plate is the same, there is no subduction of one plate under another when they meet. However, in the event of a collision, the lithosphere will be reduced to counteract the expansion zone growth.

This reduction is achieved by folding and compression that turns the lithosphere into a narrow, linear zone of activity.

In the case of plate collisions, sedimentary strata deposited at the plate margins are compressed into a series of tight fold and reverse cover zones, and fragments of the oceanic crust can be pushed onto adjacent continental crustal rocks to form ophiolite belts. The Himalayan belt is considered to be a typical example of plate collision. Continental crust and island arcs can also collide.

The plates are actually the lithosphere, containing the earth's crust and a small part of the upper mantle. Therefore, there is no division between "continental plate" and "oceanic plate", only "continental plate" and "oceanic plate" according to their composition

From the movement of the earth's crust to the origin of human beings, recording every important moment in the development of human society is the story of the earth from ancient times to the present.

This stage occurred from the end of the Late Cretaceous to the Eocene (70 35 mA), which was the early formation and evolution stage of the plateau, and was characterized by the collision of the Indian continent and the Eurasian continent. At this stage, the crustal deformation is shortened, thickened and pushed northward in the north-south direction, and its basic forms are stratigraphic folding and thrust overthrust. In the southern part of the plateau, there are Tethys Himalayan fold belt (50 mA) and Gangdis thrust fault system.

In the northern part of the plateau, the Pre-Cenozoic tectonic revival and the formation of new folds and faults, the Paleogene marine strata in the Pangong Lake-Nujiang fault zone were strongly folded, and the Cretaceous-Eocene purple-red rocks in the Kunguobaolun Mountain area further north were strongly folded and faulted and overlain by the Oligocene-Miocene clastic rock unconformity (Ren et al., 2004). At the end of the Eocene, a large area of the Qaidam Basin began to subside, and the Himalayan arc and the Qinghai-Tibet arc, which are the main tectonic bodies of the plateau, have gradually taken shape. Subsequently, meridional strike-slip occurred in the eastern part of the plateau, and left-handed shear occurred in the Altyn fault zone.

The north-east-trending fault zone of the plateau and the north-south trending faults in central Tibet along the 90 °E longitude line were activated and expanded. The east-west differences in the movement of the crust on the plateau gradually emerged.
