Definition:A divergent boundary is a linear feature on the Earth's surface where two tectonic plates move apart from each other, leading to the upwelling of magma from the mantle which then cools to form new crust. This process results in the creation of mid-ocean ridges in oceanic settings ...
The complete separation of the Somali and Nubian plates is thought to create a new ocean in between. True | False 10. There are two types of divergent plate boundaries, namely continental-continental and oceanic-oceanic. Answer Key False, because the correct statement is: The constantly-...
Ocean Trench Definition An ocean trench is a deep indent in the surface floor of the ocean and is the deepest part of the ocean. Trenches are located in subduction zones at or near a convergent boundary, continental crust, and/ or volcanic islands. The Mariana Trench is the deepest known ...

Hotspots are volcanic zones created by mantle plumes, considered hot material columns emerging from the core-mantle boundary. As with mid-ocean ridges, rising mantle rock undergoes decompression melting, resulting in vast amounts of magma.
This dissertation focuses on the origin, transport and behavior of noble gases at four different geologic settings -- (a) the San Andreas Fault Zone (SAFZ), a transform plate boundary, (b) the Costa Rica margin, a convergent plate boundary, (c) Iceland, a ridge-centered hotspot, and (d...
There is a trench within the Pacific Ocean, and the Andes Mountains are uplifted on the continent. What is a subduction zone and how does it form? A subduction zone is a convergent tectonic boundary where one plate slides beneath another. Oceanic crust is required for one to initiate. The...
Slab pull occurs at a convergent boundary and subduction zone. The force of the dense oceanic plate subducting under the continental plate and gravitationally being pulled into the mantle results in the rest of the plate being pulled along with it. Ridge push occurs along a divergent boundary. ...
Furthermore, the process of seafloor spreading is important in the formation of rift valleys because new oceanic crust is being created along the ocean floor, which leads to the development of mountain ranges such as the Mid-Atlantic Ridge. What is a Rift Valley? To define the term rift ...
A boundary is where tectonic plates meet. These tectonic plates are in constant movement, and their motion relative to each other determines the activity found at that boundary and identifies the type of boundary. A boundary between tectonic plates can be convergent, divergent, or transform. ...
