Which of these features is NOT found at a constructive plate margin?
A
Subduction Zone
B
Rising Magma
C
Plates moving apart
D
Volcanoes
Explanation: 

Detailed explanation-1: -A subduction zone is a region in which a portion of a tectonic plate sinks beneath another plate into the Earth’s interior. Subduction zones are defined by deep oceanic trenches, lines of volcanoes parallel to the trenches, and zones of large earthquakes that extend from the trenches landward.

Detailed explanation-2: -Landforms associated with constructive plate boundaries ocean ridges-such as the Mid-Atlantic ridge, where the Eurasian plate and the North Atlantic plate are moving apart from each other under the Atlantic Ocean. rift valleys-such as the East African Rift Valley where the African plate is tearing itself apart.

Detailed explanation-3: -These plates collide, slide past, and move apart from each other. Where they collide and one plate is thrust beneath another (a subduction zone), the most powerful earthquakes, tsunamis, volcanic eruptions, and landslides occur.

Detailed explanation-4: -The oceanic plate is denser than the continental plate. As they move together, the oceanic plate is forced underneath the continental plate. The point at which this happens is called the subduction zone .
