Divergence/Constructive zone/plates

Divergent plates. Image by Cornel. ZIMSEC O Level Geography Notes: Plate Tectonics: Convergence Plates

In a divergence zone plates move away from one another thus the name “divergence.”
Magma up-wells from the mantle to fill the gap left by the diverging plates.
The magma provides new material to form […]

Simple Folding. Image by Pixshark. ZIMSEC O Level Geography: Folding

Tectonic movements are those movements that result from the earth’s internal forces.
When forces move horizontally towards one another they are known as compressional.
Rocks that make up the earth’s crust are subjected to these compressional forces in a […]

Common types of faults. Image via Noaa.gov ZIMSEC O Level Geography Notes: Faulting.

Lateral earth movements often produce very great stresses due to compressional forces (when plates move towards one another) and tensional forces (pulling apart).
These forces can cause fractures or breaks in the earth’s crust.
When breaks […]
