what type of convergent plate boundary is responsible for formation of the appalachian mountains?

Collisional mountain ranges form when two continental plates converge at a continental-continental convergence zone.

At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.

When two tectonic plates meet, we get a “plate boundary.” There are three major types of plate boundaries, each associated with the formation of a variety of geologic features. If two tectonic plates collide, they form a convergent plate boundary.

Answer and Explanation: Arc-continent mountain ranges are the result of terrane accretion. The mountains formed are part of an Andean-orogenic belt mountain-building model...

Answer and Explanation: The Himalayas are made up by a converging plate boundary, which is when two continental plates crash together.

This is a special type of convergent boundary called a collisional boundary. The Himalayas in India are the result of two continental plates (the Indo-Australian and Eurasian plates) colliding head on. The third type of plate boundary is called a conservative or transform boundary.

When two plates are moving away from each other, we call this a divergent plate boundary. Along these boundaries, magma rises from deep within the Earth and erupts to form new crust on the lithosphere. Most divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges.

Mountains are usually formed at what are called convergent plate boundaries, meaning a boundary at which two plates are moving towards one another. ... Sometimes, the two tectonic plates press up against each other, causing the land to lift into mountainous forms as the plates continue to collide.

The tectonic history of the Appalachian Mountains involves opening an ancient ocean along a divergent plate boundary, closing the ocean during plate convergence, and then more divergence that opened the Atlantic Ocean.

Why? Continental-continental convergent boundaries do not have subduction zones because the two plates have equal to relatively low density and they're unable to subduct. How can oceanic sediments become part of continental mountains?

Convergent boundaries form strong earthquakes, as well as volcanic mountains or islands, when the sinking oceanic plate melts. The third type is transform boundaries, or boundaries where plates slide past each other, forming strong earthquakes.

Himalayan Mountains are an example of a Continent-Continent convergent plate boundary where two slabs of continental crust have collided and compressing the crust and the acretionary wedge material and lifting it to form the Himalayan Mountains. Indonesia is another example of an Ocean-Ocean convergent plate boundary.

Cape Fold Mountains. Fold mountains are created where two or more of Earth's tectonic plates are pushed together, often at regions known as convergent plate boundaries and continental collision zones.

Modern orogenic belts develop at convergent plate margins, where a continental margin on one plate is undercut by oceanic lithosphere of a second plate that is descending into the earth.

Examples of ocean-continent convergent boundaries are subduction of the Nazca Plate under South America (which has created the Andes Mountains and the Peru Trench) and subduction of the Juan de Fuca Plate under North America (creating the Cascade Range).

The tectonic plates that formed the boundary near the Appalachian Mountains are the North American Plate and the North African Plate.
