What Is Divergent Boundary Class 9?

What landforms are created by divergent boundaries?

Two landforms that are created from divergent boundaries are rift valleys and mid-oceanic ridges..

Is the Mariana Trench a divergent boundary?

The Mariana Plate is a micro tectonic plate located west of the Mariana Trench which forms the basement of the Mariana Islands which form part of the Izu-Bonin-Mariana Arc. It is separated from the Philippine Sea Plate to the west by a divergent boundary with numerous transform fault offsets.

What are examples of divergent boundaries?

ExamplesMid-Atlantic Ridge.Red Sea Rift.Baikal Rift Zone.East African Rift.East Pacific Rise.Gakkel Ridge.Galapagos Rise.Explorer Ridge.More items…

What are the 2 types of divergent boundaries?

There are two types of divergent boundaries, categorized by where they occur: continental rift zones and mid-ocean ridges.

What are the three types of convergent boundaries?

Convergent boundaries. Three types of convergent boundaries are recognized: continent‐continent, ocean‐continent, and ocean‐ocean. Continent‐continent convergence results when two continents collide.

What are three types of plates?

Most geologic activity stems from the interplay where the plates meet or divide. 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.

What are the three types of plate boundaries Class 9?

Tectonic Plates and Plate BoundariesThere are three main types of plate boundaries:Convergent boundaries: where two plates are colliding.Divergent boundaries – where two plates are moving apart.Transform boundaries – where plates slide passed each other.

What is the theory of plate tectonics class 9th?

Plate tectonics is the theory that Earth’s outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core. The plates act like a hard and rigid shell compared to Earth’s mantle. This strong outer layer is called the lithosphere.

What are the 3 theories of plate tectonics?

Plates interact at three types of plate boundaries: divergent, convergent and transform. Most of the Earth’s geologic activity takes place at plate boundaries. At a divergent boundary, volcanic activity produces a mid ocean ridge and small earthquakes.

Can volcanoes form at divergent boundaries?

Most volcanoes form at the boundaries of Earth’s tectonic plates. … The two types of plate boundaries that are most likely to produce volcanic activity are divergent plate boundaries and convergent plate boundaries. Divergent Plate Boundaries. At a divergent boundary, tectonic plates move apart from one another.

What is the meaning of divergent boundary?

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.

What features occur at a divergent boundary?

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 are the 4 plate boundaries?

Plate boundariesDestructive plate boundary. A destructive plate boundary is sometimes called a convergent or tensional plate margin. … Collision zones. Collision zones form when two continental plates collide. … Constructive plate boundary. … Conservative plate boundary.

Where is a transform boundary?

Transform boundaries are places where plates slide sideways past each other. At transform boundaries lithosphere is neither created nor destroyed. Many transform boundaries are found on the sea floor, where they connect segments of diverging mid-ocean ridges. California’s San Andreas fault is a transform boundary.
