dIVERGENT bOUNDARY

Plate Motion: They split and move apart.
Stress: Tensional Stress and Shear Stress Occur. when Rocks under tension expand or break apart shear stresses occurs.. When forces are parallel but moving in opposite directions the stress is called shear stress
Landform: Mid Ocean Ridge. Formed by two oceanic plates move away from each other, allowing magma to rise up from inside the Earth. When the magma reaches the bottom of the ocean, it turns in to lava and cools forming a new rock.

Diasters: a continental plate could be arched upwards from the convection current's lift, pulled thin by forces,and is fractured into rift-shaped structures, As the two plates pull apart, faults develop on both sides of the rift and the centeral blocks slide downwards. Earthquakes occur because of this fracturing.

CONVERGENT BOUNDARY

Plate Motion: when tectonic plates and fragments of the lithosphere move toward one another and collide.
Stress: The stress compresses when it comes to convergent boundaries. It's called compressive stress
Landforms: Convergent boundaries form strong earthquakes. And volcanic mountains/ islands.

Diasters: two tectonic plates of the convergent boundary move toward one another and collide. As a result of pressure, and friction, earthquakes and volcanoes occur.

TRANSFORM BOUNDARIES

Plate motion: is where the plates slide sideways past each other.
Stress: Shear stress is experienced at transform boundaries where two plates are sliding past each other.
The Plates slide past each other forming strong earthquakes.
Diasters: their plates sliding motion is known to cause lots of earthquakes
