Ocean Floor Convergent Boundary Features

The rising current pushes up on the bottom of the lithosphere lifting it and flowing laterally beneath it.

Ocean floor convergent boundary features. Divergent plate boundaries are locations where plates are moving away from one another. Three types of convergent boundaries are recognized. Where the tectonic plates of the earth s lithosphere collide convergent boundaries result. Mid ocean ridge why do earth scientists think that rigid slabs of the lithosphere are descending into the mantle near the tonga islands.

Back arc basins are often characterized by thin hot lithosphere. The following features are shown at example depths to scale though each feature has a considerable range at which it may occur. Plate tectonics dataset source school of geosciences university of sydney australia via noaa s national geophysical data center. Plates may converge directly or at an angle.

It is a subduction zone convergent. This occurs above rising convection currents. Earth rsquo s tectonic plates fit together in a jigsaw puzzle of plate boundaries. Convergent plate boundaries are often the sites of earthquakes volcanoes and other significant geological activity.

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. These spreading centers are like mid ocean ridges though the magma composition of back arc basins is generally more varied and contains a higher water content than mid ocean ridge magmas. Directory ftp link categories water. This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level.

When two plates are moving away from each other we call this a divergent plate boundary. Continent continent ocean continent and ocean ocean. The new magma molten rock rises and may erupt violently to form volcanoes often building arcs of islands along the convergent boundary. Oceanic oceanic boundaries oceanic continental boundaries and continental continental boundaries.
