Geologic Feature Formed On The Ocean Floor Divergent Boundary

Deep ocean trenches volcanoes island arcs submarine mountain ranges and fault lines are examples of features that can form along plate tectonic boundaries.

Geologic feature formed on the ocean floor divergent boundary. Mid ocean ridges are the geological features that occur at divergent boundaries. Some divergent boundaries are on the ocean floor where the lithosphere is thin. The following features are shown at example depths to scale though each feature has a considerable range at which it may occur. This divergent plate boundary moves apart at a rate of 2 5 cm per year relatively slow for a divergent plate boundary and rises 2 3 km above the ocean floor.

When the fissure opens pressure is reduced on the super heated mantle material. Volcanoes are one kind of feature that forms along convergent plate boundaries where two tectonic plates collide and one moves beneath the other. Continental shelf 300 feet continental slope 300 10 000 feet abyssal plain 10 000 feet abyssal hill 3 000 feet up from the abyssal plain seamount 6 000 feet. Divergent plates move away from each other creating a rift in the brittle rock of the lithosphere.

Running over 10 000 miles through the atlantic ocean the mid atlantic ridge is the longest mountain range on the planet. A divergent boundary occurs when two tectonic plates move away from each other. When a divergent boundary occurs beneath oceanic lithosphere the rising convection current below lifts the lithosphere producing a mid ocean ridge. It is the structure and geological processes of divergent boundaries that shape the continents and oceans over time by forming new crust and new.

Mid ocean ridges are mountains that form on the ocean floor and with a total length over forty thousand miles. 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. When two plates come together it is known as a convergent boundary. Others are on land.

The blanco mendocino murray and molokai fracture zones are some of the many fracture zones transform faults that scar the ocean floor and offset ridges see. Mid ocean ridges are mountains that form on the ocean floor and with a total length over forty thousand miles. Mid ocean ridges are the geological features that occur at divergent boundaries. This transform fault connects the east pacific rise a divergent boundary to the south with the south gorda juan de fuca explorer ridge another divergent boundary to the north.

Extensional forces stretch the lithosphere and produce a deep fissure. The impact of the colliding plates.
