Continental – Continental. Separating ←→. They form Continental Rift land forms, The type of stress is Tension
Divergent Plate Boundaries form where two plates separate. Divergent plate boundaries can also exist in the middle of a continent. They pull continents apart and form rift valleys. The East African Rift is a great example of a continental rift.
A real world example is the Mid-Atlantic Ridge. The Mid-Atlantic Ridge is a mid-ocean ridge, a divergent tectonic plate or constructive plate boundary located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world. In the North Atlantic, it separates the Eurasian and North American Plates, whereas in the South Atlantic it separates the African and South American Plates. The ridge has an average spreading rate of about 2.5 cm per year. The elevation is 7,713′

Convergent Plate Boundaries form where two plates collide. When an oceanic plate and a continental plate collide, the denser oceanic plate subduct under the edge of the continent. This create a deep ocean trench. A line of volcanoes forms above the subducting plate on the edge the continent. This process can also occur when two oceanic plates collide. The older and denser oceanic plate will subduct beneath the younger oceanic plate. This creates a deep ocean trench and a line of volcanos called an island arc.
A real world example is the Himalaya mountains in southern Asia formed as a result of the collision between the Indian Plate and Eurasian Plate which began 50 million years ago and continues today.
Transform Plate Boundary

Transform Plate Boundary They Slide past each other ↑↓. Faults. The type of stress is Shear.
Transform Plate Boundary forms where two plates slide past each other. As they move past each other, the plate can get stuck and stop moving. The stress builds up where the plates are struck and eventually the stress is too great and the rocks break. This results in a rapid release of energy as earthquakes.
A real world example is the famous San Andreas Fault. The San Andreas Fault is a continental transform fault that extends roughly 800 miles through California. It forms the tectonic boundary between the Pacific Plate and the North American Plate, and its motion is right-lateral strike-slip.
