Effects that are found at a divergent boundary between oceanic plates include: a submarine mountain range such as the Mid-Atlantic Ridge; volcanic activity in the form of fissure eruptions; shallow earthquake activity; creation of new seafloor and a widening ocean basin.

What type of feature is formed at a divergent boundary between two continental plates?

A divergent plate boundary often forms a mountain chain known as a ridge. This feature forms as magma escapes into the space between the spreading tectonic plates.

What forms when two oceanic plates meet?

A subduction zone is also generated when two oceanic plates collide — the older plate is forced under the younger one — and it leads to the formation of chains of volcanic islands known as island arcs.

What is formed at a divergent boundary in the ocean?

Divergent plate boundaries in the ocean create mid-ocean ridges. This is where new seafloor is created by upwelling magma. Divergent plate boundaries rift a continent apart. Eventually a new ocean will form between the two continents.

Which of the following is an example of a convergent oceanic oceanic plate boundary?

Examples of ocean-ocean convergent zones are subduction of the Pacific Plate south of Alaska (creating the Aleutian Islands) and under the Philippine Plate, where it creates the Marianas Trench, the deepest part of the ocean.

What causes the subduction of one of the oceanic plates?

Ocean-Continent Collisions When an oceanic and a continental plate collide, eventually the oceanic plate is subducted under the continental plate due to the high density of the oceanic plate. As time goes on the hot magma rising upward from the subduction zone causes further compression of the mountain belt.

What are examples of divergent boundaries?

Examples

• Mid-Atlantic Ridge.
• Red Sea Rift.
• Baikal Rift Zone.
• East African Rift.
• East Pacific Rise.
• Gakkel Ridge.
• Galapagos Rise.
• Explorer Ridge.

Where does a divergent plate boundary occur in the ocean?

Divergent plate boundaries are locations where plates are moving away from one another. This occurs above rising convection currents. When a divergent boundary occurs beneath oceanic lithosphere, the rising convection current below lifts the lithosphere, producing a mid-ocean ridge.

What are the effects of a divergent boundary?

Which is more dense oceanic plate or continental plate?

This theory states that the EArth’s surface is made up of slabs or rock (or plates) and these plates move with respect to each other. At an oceanic-continental convergent plate boundary, which plate will subduct? The oceanic plate because it is more dense.

What are the effects of a plate boundary?

Effects that are found at this type of plate boundary include: a rift valley sometimes occupied by long linear lakes or a shallow arm of the ocean; numerous normal faults bounding a central rift valley; shallow earthquake activity along the normal faults. Volcanic activity sometimes occurs within the rift. What is the San Andreas Fault?
