What is the name of the deep valley which lies along the east coast of Africa?
The deep valley that lies along the east coast of Africa is called the East African Rift Valley. It is a tectonic plate boundary where the African Plate is splitting into two, causing the valley to form.
How was the Challenger Deep formed?
The challenger deep was formed when the Philippine plate and the pacific plate had a collision forced the heavier pacific plate down toward the mantle, and the edge of the Philippine plate was dragged down creating a steep walled trench.

Collision of a continental and oceanic plate causes this in the plates?
The oceanic plate is forced beneath the continental plate in a process called subduction. This collision can lead to the formation of deep oceanic trenches, volcanic arcs, and earthquakes due to the intense pressure and friction between the two plates.
What causes deep ocean trenches?
Subduction is a result of a collision between two tectonic plates, either oceanic to oceanic collision or oceanic to continental plate collision. The heavier, or more dense plate sinks under the more buoyant less dense plate, and is drawn down into the upper mantle.
Deep ocean trenches are evidence for?
Deep ocean trenches are evidence for plate tectonics, showing where one tectonic plate is subducting beneath another. These trenches form at convergent boundaries when the denser oceanic plate sinks into the mantle. The presence of deep ocean trenches also indicates areas of seismic activity and potentially tsunamis.
What is the difference between the collision of an oceanic plate with a continental plate and the collision of two continental plates?
The collision of an oceanic plate with a continental plate typically results in subduction, where the denser oceanic plate sinks beneath the continental plate, creating features like deep ocean trenches and volcanic arcs. In contrast, the collision of two continental plates leads to the formation of mountain ranges due to the compression and buckling of the crust, as neither plate is subducted easily. This process can create significant geological activity, such as earthquakes, but generally lacks the volcanic activity associated with oceanic-continental collisions.
Where are convergent located?
generally in mountain ranges
Plate margins that are coming together are called what?
Convergent plate boundaries
Describe the three types of plate collisions that occur along convergent boundaries?
There are three types of plate collisions. They are classified by the type of crust involved in the collision. Plate collisions fall into these three types: 1. Both plates have an oceanic leading edge, 2. One plate has a continental leading edge and the other has an oceanic leading edge, and 3. both plates have a continental leading edge
What feature marks the location where one tectonic plate is pushed underneath another plate?
The feature that marks the location where one tectonic plate is pushed underneath another plate is called a subduction zone. In these zones, the denser oceanic plate is typically forced down into the mantle beneath a lighter continental plate or another oceanic plate. This process can lead to the formation of deep ocean trenches and is often associated with volcanic activity and earthquakes.
What is the definition of convergent boundary ocean to continent?
A convergent boundary where an oceanic plate collides with a continental plate. This collision often results in the oceanic plate subducting beneath the continental plate due to its denser nature, leading to the formation of deep ocean trenches, volcanic arcs, and earthquakes.
