At a divergent boundary of TWO OCEANIC plates, what landform is made? O trench valley O mountain O earthquake O volcano
The Correct Answer and Explanation is:
At a divergent boundary of two oceanic plates, the landform created is a volcano.
When two oceanic plates pull away from each other, the space that forms between them allows magma from beneath the Earth’s crust to rise up. This magma then cools and solidifies, gradually building up new oceanic crust. This process is typically seen at mid-ocean ridges, where the seafloor is spreading apart.
One of the most notable examples of this phenomenon is the Mid-Atlantic Ridge, where the Eurasian and North American plates are moving apart, creating a large underwater volcanic ridge. As the plates continue to separate, the rising magma creates volcanic activity, forming volcanic islands or underwater volcanoes.
The volcanic activity at these divergent boundaries is not as explosive as at convergent plate boundaries (where one plate is forced beneath another), but it is still significant. The volcanoes formed at divergent boundaries are usually shield volcanoes, characterized by broad, gently sloping sides. This type of volcano is common at ocean ridges where basaltic lava flows out smoothly and spreads over large areas.
In addition to volcanoes, divergent boundaries between oceanic plates can also lead to the formation of fracture zones or rift valleys along the ridges, but these are not as pronounced as the volcanic formations. Therefore, the correct answer to your question is volcano, since these are the prominent landforms created by the process of plate separation at divergent oceanic boundaries.
