Question

1. identify the following as either a convergent, divergent, or transform boundary.

Explanation:

1. Mid - Atlantic Ridge: It is a divergent boundary. New oceanic crust is formed as the tectonic plates move apart, allowing magma to rise and solidify.
2. East Pacific Rise: This is also a divergent boundary. Similar to the Mid - Atlantic Ridge, it is a place where tectonic plates are moving away from each other and new crust is created.
3. San Andreas Fault: It is a transform boundary. Here, two tectonic plates slide past each other horizontally.
4. Tonga Trench: It is a convergent boundary. An oceanic plate is subducting beneath another plate, creating a deep - sea trench.
5. East African Rift: It is a divergent boundary. The African Plate is splitting apart, leading to the formation of a rift valley.
6. Andes Trench: It is a convergent boundary. An oceanic plate is subducting beneath a continental plate, resulting in the formation of the Andes mountain range and the trench.

Answer:

1. Mid - Atlantic Ridge: Divergent Boundary
2. East Pacific Rise: Divergent Boundary
3. San Andreas Fault: Transform Boundary
4. Tonga Trench: Convergent Boundary
5. East African Rift: Divergent Boundary
6. Andes Trench: Convergent Boundary
