The feature that is formed at convergent plate boundaries is the East African Rift Valley.
To determine which feature is formed at convergent plate boundaries, you need to understand what convergent plate boundaries are and what kinds of geological features can form there.
Convergent plate boundaries occur when two tectonic plates collide or come together. There are three main types of convergent plate boundaries: oceanic-continental, oceanic-oceanic, and continental-continental. Each type of boundary can result in different features.
In an oceanic-continental convergent boundary, an oceanic plate collides with a continental plate. The denser oceanic plate subducts (goes beneath) the less dense continental plate. The subduction process can cause the formation of deep oceanic trenches and volcanic arcs. Examples of this include the Andes Mountains in South America and the Cascades in the western United States.
In an oceanic-oceanic convergent boundary, two oceanic plates collide. One of the plates will usually subduct beneath the other, forming a deep trench. This subduction process can also lead to the formation of volcanic islands or island arcs. One famous example of this type of convergent boundary is the Japanese Islands and the Pacific Ring of Fire.
In a continental-continental convergent boundary, two continental plates collide. The collision between two continents can result in the formation of large mountain ranges. The Himalayas in Asia, for example, were formed by the collision of the Indian Plate and the Eurasian Plate.
Now let's look at the given options:
- The East African Rift Valley is actually formed at a divergent plate boundary, where two tectonic plates move away from each other, not at a convergent boundary.
- The San Andreas Fault is a transform plate boundary, where two tectonic plates slide past each other horizontally. It is not a convergent boundary.
- The mid-Atlantic Ridge is also not a convergent boundary. It is a divergent boundary where new oceanic crust is continuously being formed as tectonic plates move apart.
Therefore, based on the information provided, none of the given options are formed at convergent plate boundaries.
