How does plate movement create mountains?
(1 point)
Plate movement creates mountains through a process called "convergent boundary." When two tectonic plates collide, their edges are pushed together and forced upwards. This collision causes the crust to crumple and fold, leading to the formation of mountains. Additionally, the intense pressure and friction between the colliding plates can cause the crust to thicken, further contributing to the growth of mountains.
So the answer is?
The answer is that plate movement creates mountains through the process of convergent boundary where two tectonic plates collide, causing the crust to fold and crumple, leading to the formation of mountains.

Plate movement creates mountains through a process called plate tectonics. This is the theory that the Earth's lithosphere, which is made up of several large plates, moves and interacts with each other.
To explain how plate movement creates mountains, let's first understand the different types of plate boundaries:
1. Convergent boundary: This occurs when two plates collide. There are three types of convergent boundaries:
a. Oceanic-Continental: When an oceanic plate collides with a continental plate, the denser oceanic plate subducts (goes beneath) the continental plate. The subduction creates a deep ocean trench and leads to the formation of mountains on the continental plate. An example of this is the Andes mountain range in South America.
b. Oceanic-Oceanic: When two oceanic plates collide, the denser one subducts beneath the other. This also creates a deep ocean trench and volcanic activity in the form of island arcs. Famous examples include the Mariana Trench in the Pacific Ocean and the Japanese island arc.
c. Continental-Continental: When two continental plates collide, neither of them can subduct because they have similar densities. This leads to the compression and folding of the crust, resulting in the formation of large mountain ranges. The Himalayas in Asia, formed from the collision of the Indian and Eurasian plates, are a prime example.
2. Divergent boundary: This occurs when two plates move apart. As they separate, molten rock rises from the mantle to fill the gap, forming new crust. This process is known as seafloor spreading. Over time, the accumulations of this new crust create underwater volcanic mountain ranges called mid-ocean ridges, such as the Mid-Atlantic Ridge.
3. Transform boundary: This occurs when two plates slide past each other horizontally. Due to the strong friction between the plates, they sometimes become locked. When the stress becomes too great, the plates suddenly slip, resulting in an earthquake. While transform boundaries are not directly responsible for mountain formation, the intense earthquakes along them can cause uplift and deformation of the crust, leading to the creation of smaller mountains and hills.
In summary, plate movement creates mountains through convergent boundaries, where plates collide and either subduct or compress and fold the crust. Additionally, divergent boundaries can form underwater mountain ranges through seafloor spreading, and transform boundaries can cause smaller mountains and hills due to the intense earthquakes that occur along them.
