A divergent plate boundary is a region where two tectonic plates move away from each other. This movement creates a gap that allows magma from the mantle to rise to the surface, forming new crust as it cools. Divergent boundaries are typically found along mid-ocean ridges, where they result in seafloor spreading, but they can also occur on land, leading to the formation of rift valleys. These boundaries are characterized by volcanic activity, shallow earthquakes, and the creation of new oceanic crust.

DIVERGENT PLATE BOUNDARY
Learning Objectives: Explain the processes that occur along divergent boundaries. Determine the results of plates that are moving apart.
Types of plate boundaries
WHAT IS DIVERGENT PLATE BOUNDARY?
Divergent plate boundary Divergent Boundary is formed when two tectonic plates move apart from each other creating tension. Molten rocks called magma rise from the Earth’s mantle to the surface. The Earth’s surface is cool enough to solidify the magma that rose, thus, creating new oceanic crust or seafloor.
Types of divergent plate boundary Oceanic-Oceanic Divergent Plate Boundary undergoes the process of formation of new crust. The geologic features or events that may occur are oceanic ridge and earthquake. Example is the Mid-Atlantic Ocean Ridge formed between the South American Plate and the African Plate.
Types of divergent plate boundary Continental-Continental Divergent Plate Boundary undergoes the process of formation of new crust. The geologic features or events that may occur are the linear sea, rift valley , and earthquake. An example is the Red Sea formed between the Arabian Plate and the African Plate.
Processes and Landforms Along Divergent Boundary Divergent plate boundaries mostly happen under the oceans. As plates pull away from each other, a vertical space that may extend deep down into the lowest layer of the crust is created. It is a rift valley . The force of separation creates a tension zone. A shallow earthquake may happen with this plate movement.
Processes and Landforms Along Divergent Boundary
Processes and Landforms Along Divergent Boundary Plate divergence is believed to be a slow continuous process. As the plates move away, the gap between them increases. While this happens, materials from the mantle may rise, filling up the space. These materials pile up near the tension zone forming mountain-like structures called oceanic ridges . But new materials from the mantle may push the old ones. The filled-up space between the plates becomes a new seafloor. This process is known as seafloor spreading .
