What are the 3 types of divergent boundaries?
What are the 3 types of divergent boundaries?
2.4: Divergent Boundaries
- Continental Rifting.
- Mid-Ocean Ridges.
What are the 3 types of plate boundaries and how do they move?
The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways in relation to each other. They move at a rate of one to two inches (three to five centimeters) per year.
What is the difference between continental divergent Boundary and oceanic divergent boundary?
oceanic plates are formed at divergent boundaries mainly at mid ocean ridges. The oceanic plate is pushed under the continental plate and melted. This melted material becomes magma that may reach the surface as volcanos, or solidify under the surface as granite. Continental plates are much thicker that Oceanic plates.
What is oceanic divergent boundary?
Oceanic-Oceanic Plate Divergence is the divergence of plate boundaries of oceanic plates. This forms a mid-oceanic ridge, which is a central ridge structure that divides the ocean basin in half. The newly formed rocks are closest to the mid-oceanic ridge and are therefore younger than those further away.
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.
What happens at divergent boundaries?
A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust. The Mid-Atlantic Ridge is an example of divergent plate boundaries.
What are some examples of divergent boundaries?
In which two places do divergent boundaries occur?
Divergent boundaries are typified in the oceanic lithosphere by the rifts of the oceanic ridge system, including the Mid-Atlantic Ridge and the East Pacific Rise, and in the continental lithosphere by rift valleys such as the famous East African Great Rift Valley.
What are examples of convergent boundaries?
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.
What landforms are created by divergent boundaries?
Two landforms that are created from divergent boundaries are rift valleys and mid-oceanic ridges.
What are 2 examples of divergent boundaries?
What are the characteristics of divergent boundaries?
Divergent plate boundaries are characterized by shallow earthquakes, volcanic eruptions, a high topographic ridge, and very young lithosphere.
What does a divergent boundary look like?
this what a divergent boundary would look like in action. divergent plate boundaries. Mid-ocean ridges located along divergent plate boundaries. A divergent boundary forms where two plates separate. When the seafloor spread at a mid-ocean ridge, lava erupts, cools, and forms new oceanic crust.
What forms at divergent boundary?
The main type of rock found at divergent plate boundaries is igneous. These rocks are formed when magma cools and becomes solid, either above or below ground.
Which feature forms at a divergent boundary?
When divergent boundaries occur in continental plates, a different geological feature, called a rift valley, is formed. These depressions slowly fill with water, forming lakes, as their level drops. Ultimately, they will form the floor of a new ocean.
Where do most divergent boundaries originate?
Most active divergent plate boundaries occur between oceanic plates and exist as mid-oceanic ridges. Divergent boundaries also form volcanic islands which occur when the plates move apart to produce gaps which molten lava rises to fill.
