What are the effects of divergent boundaries?

What are the effects of divergent boundaries?

Hear this out loudPauseEffects 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 landforms do divergent boundaries cause?

Hear this out loudPauseTwo landforms that are created from divergent boundaries are rift valleys and mid-oceanic ridges.

Do divergent boundaries cause volcanoes?

Hear this out loudPauseMost 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 do Transform boundaries cause?

Hear this out loudPauseThe grinding action between the plates at a transform plate boundary results in shallow earthquakes, large lateral displacement of rock, and a broad zone of crustal deformation. Perhaps nowhere on Earth is such a landscape more dramatically displayed than along the San Andreas Fault in western California.

What happens to the Earth at a divergent boundary?

Divergent boundaries exist both on the ocean floor and on land. The Earth has several major tectonic plates, which are sections of unbroken crust. These plates are constantly moving and consist mainly of solid rock. Collectively, these plates create the outer shell of Earth, which is called the lithosphere.

Where do divergent plate boundaries occur in the lithosphere?

Divergent Plate Boundaries. Divergent plate boundaries are locations where plates are moving away from one another. This occurs above rising convection currents. The rising current pushes up on the bottom of the lithosphere, lifting it and flowing laterally beneath it.

How does a divergent fault differ from a convergent fault?

Divergent faults create gaps or sags. When plate boundaries are convergent there is always a subduction zone. When divergent, they usually open valleys on land and oceanic ridges like the Mid Atlantic Ridge. The San Andreas Fault is a place where two tectonic plates touch, the North American and Pacific Plates.

How are volcanic islands formed at a divergent boundary?

Divergent boundaries also form volcanic islands, which occur when the plates move apart to produce gaps that molten lava rises to fill. Current research indicates that complex convection within the Earth ‘s mantle allows material to rise to the base of the lithosphere beneath each divergent plate boundary.
