Scientists speculate that the movement of tectonic plates is created by the movement of the rigid lithosphere on the asthenosphere.
The softer layer below the lithosphere is the asthenosphere. The asthenosphere begins at a depth of approximately 150 km. It has convection currents that arise from the heating and subsequent rising of material from the lower asthenosphere. These convection currents drive the movement of lithospheric plates at the surface, and are the cause of tectonic activity.
The failure of replicated chromosomes to separate is called nondisjunction. This will cause extra or missing chromosomes in the daughter cells.
The lithosphere is the Earth's outermost crust. The asthenosphere is a ductile, somewhat deformable, layer 60-150 miles (100-250 km) below the Earth's surface, under the lithosphere. Movements between the two layers cause earthquakes.
it can cause Trisomy 21 because an extra chromosome can be added.

The convection currents running through the asthenosphere are widely believed to be the source of movement of the tectonic plates.

UVA rays penetrate the skin more deeply and can cause melanoma in susceptible people. UVB rays, which don't penetrate as deeply, cause sunburn and wrinkling.
