A basic mountain should be formed from the collision of continental crust and oceanic crust
AnswerWhen an oceanic and a continental crust collide, the heavier oceanic crust tends to subduct under the lighter continental crust. Because of the collision and corresponding compression and also because of volcanism related to dehydration and melting of the subducted plate a mountain range is formed. The Andes mountain range is a, if not the, most typical example.

How do oceanic and continental crust differ?
Oceanic crust is typically thinner, denser, and younger than continental crust. It is primarily composed of basaltic rocks and forms the ocean floor, while continental crust is thicker, less dense, and contains a wider variety of rock types, including granitic rocks. Continental crust forms the continents and is older than oceanic crust.
What type of rock makes up the continental and oceanic crust?
The continental crust is mainly composed of igneous rocks like granite and metamorphic rocks like gneiss. The oceanic crust is primarily made of basalt, which is an igneous rock that forms from cooling lava at mid-ocean ridges.
What type of mountain forms because of an oceanic plate and a continental plate coliding'?
When an oceanic plate and a continental plate collide, it results in the formation of a mountain range called a continental-continental convergent boundary. This collision results in intense folding and faulting of the Earth's crust, leading to the uplift of mountain ranges such as the Himalayas.
Differences of the continental crust and oceanic crust?
The continental crust is thicker, less dense, and older than the oceanic crust. It is composed mainly of granite rocks and is found beneath continental landmasses. In contrast, the oceanic crust is thinner, denser, and younger, with basalt rocks being the dominant rock type. It forms the ocean floor and is continually created and destroyed through the process of seafloor spreading and subduction.
What Is the crust that forms the continents?
The crust that forms the continents is called continental crust. It is thicker and less dense than oceanic crust, composed mainly of granite rock. Continental crust is what makes up the landmasses on Earth's surface.
How does a trench forms?
They form when the oceanic crust goes under the Continental crust. The oceanic crust then forms the trenches through a process called subduction.
What happens to the leading edges of convergent plates as they collide?
This depends on what material (oceanic crust or continental crust) the leading edges are made of. When Continental crust hits Continental crust (eg India ploughing into Asia) the crust thickens by thrusting and folding and a mountain belt forms (the Himalayas). There is little or no volcanic activity associated with this sort of collision. When Oceanic crust meets Continental crust (eg the Pacific plate and the west coast of South America), the oceanic crust sinks below the continental crust forming an oceanic trench on the oceanic side (a subduction zone) and a mountain belt on the continental side (by folding and uplift). This sort of collision produces a large amount of volcanic activity. When Oceanic Crust meets Oceanic Crust, the actively spreading side sinks below the stationary side to form a back arc basin associated with island arcs and subduction zones (eg the Caribbean or the east of Papua New Guinea). This sort of collision also involves a large amount of volcanic activity.

How does trench formed?
They form when the oceanic crust goes under the Continental crust. The oceanic crust then forms the trenches through a process called subduction.
Which rock makes continental and oceanic crust?
The rock that makes up both continental and oceanic crust is called basalt. Basalt is a mafic extrusive igneous rock that forms when lava cools and solidifies rapidly at the Earth's surface. It is commonly found in oceanic crust, while continental crust is made up of a variety of rocks including basalt.
How does a deep-ocean trench form?
They form when the oceanic crust goes under the Continental crust. The oceanic crust then forms the trenches through a process called subduction.

What Is the crust that forms the continents?
The crust that forms the continents is called continental crust. It is thicker and less dense than oceanic crust, composed mainly of granite rock. Continental crust is what makes up the landmasses on Earth's surface.
Does Rhyolitic magma forms beneath continental or oceanic crust?
Rhyolitic magma typically forms beneath continental crust due to high silica content and low temperature. The silica-rich composition leads to viscous magma, which is more common in continental settings compared to oceanic crust where magma tends to be more basaltic and less viscous.
What forms when continental crust converge with oceanic crust?
Deep sea trenches, Mountain ranges, Volcanoes, and Earthquakes.
