GEOLOGY

Detailed explanation-1: -When two plates come together, it is known as a convergent boundary. The impact of the colliding plates can cause the edges of one or both plates to buckle up into a mountain ranges or one of the plates may bend down into a deep seafloor trench.

Detailed explanation-2: -Convergent (Colliding): This occurs when plates move towards each other and collide. When a continental plate meets an oceanic plate, the thinner, denser, and more flexible oceanic plate sinks beneath the thicker, more rigid continental plate. This is called subduction.

Detailed explanation-3: -Convergent Plate Boundary-Oceanic When a convergent boundary occurs between two oceanic plates, one of those plates will subduct beneath the other. Normally the older plate will subduct because of its higher density.

Detailed explanation-4: -Examples. The collision between the Eurasian Plate and the Indian Plate that is forming the Himalayas. Subduction of the northern part of the Pacific Plate and the NW North American Plate that is forming the Aleutian Islands. Subduction of the Nazca Plate beneath the South American Plate to form the Andes.

Detailed explanation-5: -Divergent boundaries–where new crust is generated as the plates pull away from each other. Convergent boundaries–where crust is destroyed as one plate dives under another. Transform boundaries–where crust is neither produced nor destroyed as the plates slide horizontally past each other.
