The smear is stained with a special dye, which helps tell the difference between various types of white blood cells. Five types of white blood cells, also called leukocytes, normally appear in the blood: 1  Neutrophils.  Lymphocytes (B cells and T cells)
What type of plate boundary leads to subduction? Convergent plate boundaries lead to subduction. Subduction occurs  when one tectonic plate rides over the edge of another tectonic  plate which sinks into the mantle as theyâ¦ converge.
Convergent Boundaries. Introduction. Convergent boundaries form when two crustal plates are colliding. The plates form a subduction zone with one plate descending beneath the other plate. One of the converging plates must be an oceanic plate to form a subduction zone. When two continental plates collide mountain ranges like the Himalayas form. Trenches form at subduction zones, USGS. Subduction zone. The subducting plate is being recycled as it begins to melt at about 100 kilometers. The water soaked oceanic plate forms molten rock that collects in magma chambers.
